How to Select Helical Gear Reducer?

Product characteristics of the helical gear reducer Highly modular design, installation location is unrestricted, high strength, small size, long life, low noise, high efficiency, can withstand greater radial load, can withstand axis load not more than 5% of the radial force.

1. Selection of models at the helical gear reducer selection Usually it is determined by the customer according to the form of drive mounting arrangement. GR, GF series helical gear reducer are used for the input shaft and output shaft parallel occasion, that is the parallel shaft helical gear reducer we often say, GS, GK Series are used for the input shaft and output shaft vertical occasions.

2. The determination of actual condition coefficient fa (see sample) 1) General requirements 2) Special use requirements

3. The determination of the model (specifications) Must satisfy the condition fb> = fa

1) Constant power selection (1) Motor and reducer straight or connect by coupling (2) The motor and reducer is connected by pre-reducer coupling



2. Constant torque selection (generally used when reducer and r series helical gear reducer in dual-class series) Check the selection parameter table by motor power, stages and transmission ration (constant torque). At this time, the working torque must be limited in the maximum torque range of the selected deceleration.

4. Radial load test When the reducer shaft head is equipped with gears, pulleys, sprockets, it will produce a large radial load. In this case, we need to test the radial load. See the aforementioned selection parameter table definitions.

5. Installation conditions test This inspection should be carried out if there are size installation restrictions. I.e. compare the chosen machine model structure dimensions and the dimensions of the space. If all of the above can be met, write according to the respective machine model method. If there are special requirements, it can be described in texts. Helical gear reducer model can take reference to the s series reducer representation.

We need to understand the ordinary supplier conventions when considering how to select helical gear reducer:

1. Y2 series motor supply is IP54 degree of protection, F class insulation, but should be Class B insulation conditions in general use unless there is other statement, for example, when spiral bevel gearbox reducer is equipped 3KW motor, 3KW motor protection class is IP54 and insulation class is F grade.

2. If not indicate the motor terminal box position, usually supply according to the 0 ° position of the installation diagram.

3. If not particularly point out the input and output shafts spin relationship, generally not make logo on the reducer.

4. The reducer should be added with lubricant before being shipped out of the factory.

5. Installation structure size icon indicates the attachment outside the standard scope of delivery is generally not available.
