specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 Describe this embodiment, a built-in compact winch transmission device in this embodiment includes a chassis 1, a first ring gear 2, a first transparent cover 3, a drum 4, a first bearing cup 5, a second transparent cover 6. Bracket 7, transmission box 8 and first bearing 9, transmission box 8, first ring gear 2, first transparent cover 3, roller 4, first bearing cup 5, second transparent cover 6 and bracket 7 from the left To the right, it is fixedly arranged on the bottom frame 1 in turn, and the first bearing 9 is arranged between the drum 4 and the first ring gear 2, the transmission box 8 is fixedly connected with the first ring gear 2, and the first bearing cup 5 1. The second transparent cover 6 is fixedly connected with the drum 4, and a built-in compact winch transmission device also includes a primary transmission device 33, a secondary transmission device 34 and a tertiary transmission device 35, and a primar...

specific Embodiment approach 2

[0016] Specific implementation mode two: combination figure 1 To illustrate this embodiment, each secondary transmission planetary device 20 of this embodiment includes a secondary transmission sleeve 37, two secondary transmission bearings 38 and a secondary planetary wheel 39, and the secondary transmission sleeve 37 is set on the secondary transmission pin On the shaft 23, two secondary transmission bearings 38 are respectively arranged on both sides of the secondary transmission sleeve 37, and the secondary planetary gear 39 is set on the secondary transmission bearing 38, and the secondary planetary gear 39 is in phase with the first internal ring gear 2 engage. Such setting facilitates the realization of a large transmission ratio and effectively adjusts the rotational speed of the drum of the winch. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0017] Specific implementation mode three: combination figure 1 To illustrate this embodiment, each secondary transmission planetary device 20 of this embodiment also includes two circlips 40 for secondary holes, and the two circlips 40 for secondary holes are respectively arranged on two secondary transmission bearings 38 On the secondary drive sleeve 37 of the inner side. With such setting, the axial fixing effect is the best. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a built-in compact-typed winch transmission device, which relates to a winch transmission device, and solves the problems that both a secondary transmission device and a tertiary transmission device of present winch are arranged outside the winch transmission device, the occupied space is large, and the requirement on the construction environment of the winch is high. A transmission case, a first inner gear ring, a first through cover, a roller, a first bearing cup, a second through cover and a bracket are sequentially fixed on an under-frame from left to right, wherein the transmission case is connected with the first inner gear ring through a plurality of hinged bolts, the first bearing cup and the second through cover are connected with the roller through a plurality of connection bolts, and a primary transmission device, a secondary transmission device and a tertiary transmission device are sequentially arranged inside the transmission case and the roller from left to right. Both the secondary transmission device and the tertiary transmission device are arranged inside the roller, so the structure is compact, the occupied space is small, and the problem of the high requirement on the construction environment of the winch can be effectively solved. The built-in compact-typed winch transmission device is particularly suitable for the transmission device of a slow winch.

Description

technical field [0001] The invention relates to a winch transmission device, in particular to a built-in compact winch transmission device. Background technique [0002] A winch is a machine that has one or several horizontally installed reels or winches that can wind ropes. The winch has high versatility, compact structure, small size, light weight, heavy lifting, and convenient use and transfer. It is widely used in lifting or flat dragging of materials in construction, water conservancy projects, forestry, mines, docks, etc. It can also be used for modern electronic control. The supporting equipment of the automatic operation line, with the increase of the application range of the winch, puts forward higher requirements on the performance of the winch in all aspects. The two-stage transmission and the three-stage transmission of the existing winch are placed outside the winch transmission. It takes up a lot of space and has high requirements on the construction environme...
