Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the embodiments.

[0013] This embodiment proposes a new type of planetary reduction box, which is mainly used for hoisting structures or equipment in similar working conditions. like figure 1 As shown, it includes a fixed flange 1 and an output flange 4. The large end face of the fixed flange 1 is used for fixed connection with the motor casing of the hoisting mechanism, and the outer side of the small end face is connected to the output flange 4 through the bearing 3, so that the output flange 4 can be rotated relative to the fixed flange 1 .

[0014] The fixed flange 1 is provided with a coupling 14. The coupling 14 in this embodiment adopts a claw coupling 14, including a motor end claw 15, an elastic block 16 and an input convex claw 17. The motor end convex claw 15 is used for In the fixed connection with the motor shaft of the hoisting mechanism, one side of the input pawl 17 is...

Abstract

The novel planetary reduction gearbox comprises a fixed flange and an output flange, one side of the fixed flange is fixed to a power mechanism, the other side of the fixed flange is connected with the output flange through a bearing, and a coupler is installed in the fixed flange through a bearing; a fixed gear ring, an output gear ring and a planetary gear mechanism are arranged in the output flange, the fixed gear ring is fixed on the fixed flange, the output gear ring is fixed on the output flange, the fixed gear ring and the output gear ring are arranged side by side and have a tooth number difference, the planetary gear mechanism comprises a sun gear shaft and a planetary gear, and the sun gear shaft is connected with the coupler. The planetary gear is meshed with the fixed gear ring and the output gear ring at the same time; compared with the prior art, the two split type gear rings are adopted to replace a multi-stage gear ring in the background technology, the machining difficulty can be effectively lowered, the number of parts can be reduced, meanwhile, a large speed ratio can be kept on the basis that a transmission chain is shortened, and the gear ring has the advantages of being novel in structure, efficient in transmission, easy and convenient to manufacture, stable, reliable and the like.

Description

technical field [0001] The invention belongs to the technical field of planetary reduction boxes, and in particular relates to a novel planetary reduction box. Background technique [0002] The traditional hoist planetary reduction box adopts NGW series three-stage planetary transmission structure. The motor is connected to the input end of the reducer through a coupling, and after three-stage deceleration, it is output through the final stage planetary carrier. In order to achieve a large speed ratio, the traditional planetary gear box generally undergoes multi-stage planetary reduction, and the transmission chain is long; the multi-stage planetary reduction components make the axial size of the reduction box large. [0003] ZL200820023058.8 Planetary reducer for overhead crane trolley The planetary reducer changes the original reducer from NGW series planetary transmission to planetary differential transmission, and changes the output of the final stage planetary carrier t...
