Embodiment Construction

[0019] The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

[0020] like Figure 1 to Figure 4 As shown, an axially adjustable combined planetary carrier includes a disc-shaped A planetary carrier 2 and a disc-shaped B planetary carrier 15 arranged relatively parallel to the A planetary carrier 2, the A planetary carrier 2 and the B planetary carrier 15 are equal in diameter. There is a mounting hole in the center of A planetary carrier 2, and the installation hole of A planetary carrier 2 is a stepped hole. The diameter of the stepped hole of A planetary carrier 2 near the B planetary carrier 15 is larger than the diameter of the A planetary carrier 2 stepped hole away from the B planetary carrier 15 side. The diameter; there is an internal spline on the section with the smaller diameter of the stepped hole of A planet carrier 2. A planetary carrier 2 and B planet...

Abstract

The invention discloses an axially-adjusted combined planet carrier for multi-stage planetary gear transmission, and belongs to the technical field of planetary gear transmission reducers. The axially-adjusted combined planet carrier comprises a planet carrier body A and a planet carrier body B, and the planet carrier body A and the planet carrier body B are oppositely arranged in parallel. The planet carrier body A and the planet carrier body B are connected through a plurality of planet gear shafts, and the planet gear shafts are evenly distributed around the center of the planet carrier body A. A mounting hole is formed in the center of the planet carrier body A. An adjusting shaft is mounted at the center of the planet carrier body B, and the adjusting shaft is mounted on a rear cover. The adjusting shaft is provided with an adjusting sleeve. Adjusting sleeves and adjusting shafts of different axial lengths are produced and assembled according to an adjusting assembling method, so that an adjusting gap delta is guaranteed. The axially-adjusted combined planet carrier integrates the advantages of the planet carrier body A and the advantages of the planet carrier body B, a blank of the axially-adjusted combined planet carrier is easy to form and convenient to machine and assemble, and the overall force bearing status of the axially-adjusted combined planet carrier is superior to that of a third planet carrier; in addition, the axially-adjusted combined planet carrier can be axially adjusted and shows excellent performance in the reality.

Description

technical field [0001] The invention relates to a planetary gear transmission reducer, in particular to an axially adjustable combined planet carrier for multi-stage planetary gear transmission. technical background [0002] At present, planetary gear transmission technology is quite mature. Multi-stage planetary gear transmission, especially its input stage, has the characteristics of high speed and heavy load. It has particularly high requirements on the strength and adjustability of the planetary gear frame. For the existing technology, the force of the planetary gear frame should be reasonably optimized. The structure and its axial positioning and adjustment are all the more important. [0003] The planetary carrier structure is generally divided into double-wall integral type, double-wall split type and single-wall type. For the first two types of planetary carrier, blank forming, machining and assembly are more complicated. And it is not good for the third kind of st...
