Het kiezen van een reductieversnellingsbak: Machine-eisen Omzetten in Vergelijkbare Voorstellen

Wanneer een klant op zoek is naar een reductieversnellingsbak, Het eerste criterium is meestal het vermogen van de motor, en de gewenste verhouding. Die stukjes helpen om de zoektocht te verfijnen, but they don't answer all the important questions. What should be at the output shaft of the machine, how frequently does the load change and what arrangement will suit the machine?

Equipment builders and OEM buyers will find the most productive method to be developing a short application brief prior to picking a series. This guide outlines the process of translating machine requirements into a shortlist, based on Mingye's real product families, and without making the assumption that one type of gearbox will be suitable for any machine application.

Using a descriptive word to identify the data that is being outputted is a very good way to explain the program.

A reduction gearbox is used to reduce the speed and increase the torque available subject to mechanical losses and rating. It does NOT increase the power output. Decide on the required speed and load for the machine first and then decide the necessary input power and transmission arrangement to obtain the required speed and load.

Write the requirement as a function of the driven. A certain belt speed is required for a conveyor, and needs to be converted to a roller speed. The right mixer type, speed and torque are necessary for a process. Based on that machine calculation, the output of the gearbox is determined.

State production output speed min, normaal, max, if the production varies. Also determine if the item being quoted is a reducer only or is a complete gear motor. The electrical information, mechanical interfaces and assembly responsibility change when the motor is included which must be confirmed.

Take advantage of the Ratio to Connect Speed and Torque

Reductieverhouding (RR) is the ratio of the speed of the input to the speed of the output. Bijvoorbeeld, if input is 1440 rpm, and the ratio is 30:1, the output will be 48 rpm. Note that an expectation may be different based on a calculation using the nominal synchronous motor speed, so use the applicable operating speed.

Estimated output torque is the motor torque x ratio x gearbox efficiency for steady motoring operation. Or, torque in Nm is about 9,550 x shaft power in kW divided by shaft speed (in toeren). Power and speed stay on the same shaft – not motor input power is automatically gearbox output power.

Mingye's Industrial Gearbox Torque Sizing Guide distinguishes Running, Startup, Peak and Shaft-load checks. After the speed relationship has been determined, check the torque required against the torque permissible of the selected unit for the duty. Ratio is NOT an approval of capacity.Ratio is not an approval of capacity.

Let Shaft Geometry reduce the Product Family!

Draw the positions of the motor and the motor driven shaft before comparing product names. For different types of machine layout, the motor is installed in- or out-line, parallel-offset or right-angle. Provide space for coupling, Bewakers, cable access and clearance for assembly removal.

Mingye's R-serie Helical Gear Motor is a modular motor and mounting helical gear motor that offers an inline helical option. F-serie parallelle as spiraalwielmotor is a different shaft relationship for compact convey and mechanical drive layout. Both should not be chosen just because it has the same power rating as a motor that already is in place.

In cases where layout calls for a perpendicular power path, Mingye also provides K-series helical bevel and RV worm products. For specific needs, there are planetary and cycloidal products to offer further architectures. Look first at geometry and operating priorities, then compare models, don't make comparisons of every family with a generic efficiency or torque comparison.

Convert Production Cycle to Rating Information.

Normal duty of a machine is not only the load it has to carry during normal operation. Accelerating a large inertia (Onder belasting), Achteruitkeren, and process disturbances (occasionally) can create greater demands. Express the duration of each event and the frequency of each event.

Provide the hours of operation per day and the number of starts per hour (and indicate any planned changes in production rate). After determining the physical load, apply selected manufacturer's service-factor method. Rate all the mechanisms beforehand and be sure that a single mechanism has only one factor, or that a factor is not used twice without verifying this.

If a variable-speed application, specify the desired motor-control range desired for the application. Motor cooling for low speed, gearbox lubrication and torque-speed envelope allowed need to be reviewed. When trying to increase the drive frequency, input speed-limit should be checked, ook. The rated operating point does not make a gear motor suitable for use over an unlimited speed range.

Identify when the process requires the assistance of a specialist Reducer.

In addition to speed reducing and providing the right kind of shaft layout, some machines require more. The needed bearing arrangement and housing structure may be dictated by process forces and therefore an application-specific gearbox would be pertinent from the outset.

The single screw extruder gearbox of Mingye is described for continuous extrusion service, which includes the axial load of the screw. On its product information it talks about a thrust bearing. Don't assume a matching ratio/general purpose drive of the same nominal power can generate the same thrust.

Describe the material, processing conditions and mechanical forces in response to a specialist configuration. Verify the location of those forces and what interfaces need to interface with the existing equipment. This is also why if the output speed is the same, it may be necessary to review the machine-level to change the gearbox family.

Review Installation Conditions Prior to Freezing the Design

Check output shaft/bore size, Keyway, flange register, mounting pattern and rotation references on the proposed drawing. Apply loads radially and axially, including location of any pulley/sprocket. The torque capacity and output-bearing suitability are independent from each other.

Document ambient temperature, Vocht, Stof, cleaning and access restrictions. Check lubrication requirements for a specific model and directions, as well as inspection and service clearance. If a drain is not easily accessible or a motor fan is clogged, this can present an operating issue after a successful installation.

The Machining and Inspection capabilities are displayed on Mingye's Manufacturing Overview. Request product controls and records pertaining to the hardness value or gear-accuracy claim being used rather than simply transferring a hardness value or gear-accuracy claim from another series.

Don't just consider headliner prices, always compare complete proposals.

Using the same application brief, ask suppliers to quote. Determine if each proposal contains documentation, mounting accessories, Smeermiddel, koppeling, and adapter (indien van toepassing) and motor. Don't allow some cheaply priced item to be sold as a different supply scope that is simply being bundled in to the bill.

Mingye biedt the customization of modular gearboxes in terms of mounting dimensions and ratios, as well as customization according to the application. Have proposed adaptation confirmed on drawing and check against the operating duty. Another product limit is not a result of a modified interface and the torque capacity does not automatically increase.

A reduction gearbox is a suitable reduction that converts the requirement of the machine to an installable and maintainable machine. They can more easily compare quotations, and engineering, purchasing, and installation teams have a common frame of reference for approving it, when they have a clear brief.

Veelgestelde vragen

Q1. Which would make the motor spin faster, a reduction gearbox or a drive sprocket?

Nee. It compromises speed for torque and some amount of power in the process due to friction losses and other losses. The total drive rating still determines the total output that’s available.

Q2. Will motor power be sufficient to choose a gearbox?

Nee, there are other factors, such as the output speed, koppel, Duty cycle, mounting and external loading. Know the full operating requirement, and select a model.

V3. Is mechanical reduction replaceable with a Frequency Converter?

Not in all the uses. Motorkoppel, Koeling, speed range and machine load must be checked in conjunction with each other. Mechanical reduction may be required.

Q4. Can you interchange gearboxes having the same ratio?

Nee. Torque values, Interfaces, geometry of shafts, bearings and lubrication needs may vary. Make a comparison between the full setting and accepted dimensions.

V5. Can the OEM equipment be adapted with a standard gearbox, using the Can Mingye gearbox?

Customization of mounting dimensions, ratios and application-specific configurations are described in the website. Verify before ordering the feasibility and the resulting ratings for the specific project.
