High reliability worm gear rotary reducer
Worm gear rotary reducers have the characteristics of small , light , large torque, high start and transimission efficiency ,low noise , etc . Output shaft can bear ;arge radial force.
It can be applied in kinds of hydraulic transimission system and rotating facilitites.
Performance parameters and dimensions
1) Each minimum value is for reference only in the design range. For specific selection, it is necessary to specify the size.
2) Output pinion gear number, modulus, given at the time of ordering.
3) The flange bolts are graded 10.9.
4) The dimensions D1, D2 are determined by the pinion structure, and the smaller dimensions need to be explained first.
5) For special installation, higher torque and non-standard speed performance requirements, please contact us.
Another: For the following two types of installation requirements, please request the installation size as an order drawing
Nominal transmission ratio
In order to ensure the normal operation of the slewing mechanism, the mounting center hole of the steel structure must be concentric, and the flange mounting surface must be perpendicular to it. The relative position between the mounting hole of the steel structure and the mounting surface of the flange is not allowed to change excessively under the influence of environmental influences and external forces. The recommended tolerances are as follows.
A: When the workpiece rotates around the reference centerline, the amount of axial runout in any measurement plane must not exceed the value
B: The centerline of each machining axis hole must be located in a cylinder whose deviation from the centerline of the reference plane is this value.
Oil selection and replacement
The correct choice of oil and reasonable maintenance can extend the service life of the reducer.
New reducer or replacement repaired reducer. Use oil for the first time after 200 hours. Replace oil every 1000 hours. Change oil at least once a year.
Add it once a week or 50 hours after work
(3) Recommended Lubricant:
This product can be widely used in the field of lifting machinery，including bridge crane, gantry crane, tower crane, mobile crane, gantry crane, elevator, cable crane, mast crane and mechanical parking equipment.
All exported gearboxes covered with Anti rust oil and plastic film, then packed in wood box with Fumigation.
Gearbox processing technology
