Abstract
The utility model relates to a rotary speed reducer for engineering hanging, which belongs to a triple planetary gear transmission device and is characterized in that an input shaft of the rotary speed reducer is connected with a motor shaft through a gear sleeve between a machine case and a machine body, an output gear is engaged and connected with a gear arranged on a rotary disc, and an oil cup is connected onto a brake arranged on a motor and the machine case of the rotary speed reducer. The rotary speed reducer has the characteristics that the speed ratio is great, the rotation is fast, the structure is compact, the performance is reliable, and simultaneously, the oil is not outwards leaked and seeped.
Description
Technical field
The utility model relates to retarder, particularly relates to the rotary reducer of using with the engineering sling cart.
Background technique
Current, with the rotary reducer of engineering sling cart coupling, its speed ratio is big, rotation is slow, and supporting with it internal gear is big, also often outwards oil impregnate, leakage of oil, long, poor stability of the time that it lifts the engineering sling cart.
Summary of the invention
The purpose of this utility model is to provide a kind of novel rotary reducer, and it is a kind of reliable performance, device simple in structure.
The technical solution of the utility model is:
The utility model rotary reducer is the third-level planetary gear drive, it is between casing and body, its input shaft and motor shaft are connected by the tooth cover, and output gear is connected with gear engagement on the rotary disk, and lubricating cup is connected on the casing of break on the motor and rotary reducer.
One end of the sun gear of the primary planet pinion transmission device of rotary reducer is connected by the tooth cover with motor shaft, the primary planet pinion transmission device comprises one-level sun gear, one-level planet wheel, primary planet carrier, one-level internal gear, one-level sun gear and the engagement of one-level planet wheel, one-level internal gear and the engagement of one-level planet wheel; The primary planet pinion transmission device is connected with a joggle by the secondary sun gear of primary planet carrier and secondary planetary gear transmission device, the secondary planetary gear transmission device comprises secondary sun gear, secondary planet wheel, secondary planet frame, secondary internal gear, secondary sun gear and the engagement of secondary planet wheel, secondary internal gear and the engagement of secondary planet wheel; The secondary planet transmission device is by three grades of sun gear engagements of secondary planet frame and third-level planetary transmission gear means, the third-level planetary gear drive comprises three grades of sun gears, third-level planetary wheel, third-level planetary frame, three grades of internal gears, three grades of sun gears and the engagement of third-level planetary wheel, three grades of internal gears mesh with the third-level planetary wheel; The internal tooth of third-level planetary frame and gear shaft one end is connected with a joggle, and gear shaft the other end external tooth is in the outside of body.
Good effect of the present utility model is:
1, the utility model speed ratio big, rotate fast, compact structure, short with the time of engineering loop wheel machine supporting back lifting, operate steadily, efficient height, noise be little.
2, lubricating cup of the present utility model also can be discharged the gas that produces in the rotary reducer except the oil lubrication of supplying with rotary reducer.Carry the band oil ga(u)ge, the position of the relative vent hood of pasta is lower, and vent hood is easy to leak oil not.
