Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] refer to figure 1 A cycloid deceleration device for a rocket launch platform, characterized in that:

[0023] The two-stage deceleration device composed of bevel gear pair and cycloid transmission, in which the large bevel gear is connected to the input end of the cycloid transmission input shaft, the biggest advantage of adopting the two-stage deceleration structure of bevel gear + cycloid is the high degree of light weight, The structure is simple and the cost is low.

[0024] The cycloid deceleration device of the rocket launch platform is characterized in that:

[0025] (A) Cycloid transmission consists of machine base (1), output shaft (3) and support bearing (2), cycloid wheel (5), eccentric bearing (6), pin gear housing (8), pin gear pin (17 ), front frame (11), input shaft (12) and W output mechanism, W output mechanism includes column pin (10), column sleeve...

Abstract

The invention relates to the technical field of speed reducers, in particular to a cycloid speed-reducing device of a rocket launching movable platform, which is characterized in that the cycloid speed-reducing device is a two-stage speed-reducing device comprising a bevel gear pair and a cycloid transmission, wherein (A) the cycloid transmission comprises a base, an output shaft, a supporting bearing, a cycloid gear, an eccentric bearing, a needle-tooth shell, a needle-tooth pin, a front base, an input shaft and an W output mechanism, wherein an input shaft is supported on an inner hole of the front base by bearings, the shaft-extension end of the input shaft is connected with the eccentric bearing, and the input end is connected with a large bevel gear; the front stand is sequentially connected with the needle-tooth shell and the base; the output shaft is supported on the inner hole of the base by the bearings; and (B) two symmetrical small bevel gear shafts meshed with the large bevel gear are both supported in a box wall hole of the front base by the bearings, wherein one small bevel gear shaft is connected with a motor, and the other small bevel gear shaft is connected with amanually-operated handle. The cycloid speed-reducing device has the advantages of two-stage speed reduction, short axial size, light weight and high quantization; in addition, as cycloid gear teeth and semi-buried teeth are continuous, the cycloid speed-reducing device has larger bearing capacity than that of a planetary transmission with only four planet gears; moreover, the cost of the cycloid speed-reducing device is lowered by 40%-55%.

Description

【Technical field】 [0001] The invention relates to the technical field of reducers, and relates to a cycloidal reducer for a rocket launching movable platform. 【Background technique】 [0002] The deceleration device of the rocket launch platform must have high reliability, long service life, and high light weight.
