Rotary Platform Speed Reducer

Low Noice Rotary Platform Speed Reducer

Model description

1.The three stage planetary size is 60, the A type is installed with the eccentricity of 2.5, and the transmission ratio is 140.

If you have special requirements, please explain when you order.

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

Reducer selection

T 2 (N.m): Output pinion load torque

T 2k—Modified load torque

K - Coefficients corresponding to the utilization level and load status of the table organization

The rated torque of the gearbox selected must satisfy the following formula:

T 2k=T 2×K<Tnom (see parameter table)

Selection examples

Select a bulk cargo ship to use the slewing speed reducer for crane lifting, press the FME equipment classification as M5 (T5-L2), consider the pinion gear load torque M=41000N.m after various load conditions, output gear M=16 Z=12 X = 0.58 B = 180, mating gear M = 16 Z = 146 X = 0.5. Pinion output speed 15rpm

Select calculation:

Working load torque: T 2 = 41000N.m

Check the work table K=1, the pinion speed is in the normal range

Check table DLS050 rated torque value Tnom = 44000N.m

T 2k = T 2 × K = 41000 × 1 = 41000 <Tnom = 44000

So use DLW050 to meet the requirements of rotary speed reducer

Installation instructions

In order to make sure the traditional operation of the slewing mechanism, the mounting center hole of the steel structure should be concentric , and therefore the rim mounting surface should be perpendicular to that. The relative position between the mounting hole of the steel structure and therefore the mounting surface of the rim isn't allowed to alter too beneath the influence of environmental influences and external forces. The counseled tolerances ar as follows.

A: Once the work rotates round the reference line, the number of axial runout in any measuring plane should not exceed the worth

B: The line of every machining axis hole should be placed during a cylinder whose deviation from the line of the reference plane is that this price.

Oil selection and replacement

The correct choice of oil and reasonable maintenance can extend the service life of the reducer.

(1) Lubricants:

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.

(2) Grease:

Add it once a week or 50 hours after work

(3) Recommended Lubricant:

Application

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.

Packaging

All exported gearboxes covered with Anti rust oil and plastic film, then packed in wood box with Fumigation.

After-sale service

During the usage of the gearbox，if you've got any valuable comments or suggestions for improvement, please be at liberty to contact our sales force, technical department or service department. Any of your suggestion are our continuous power to maneuver on!
