Abstract
The utility model discloses a cantilever support type power takeoff mechanism, which consists of a torque converter casing, a power takeoff port gear, a gear shaft, bolts, gaskets, a bearing and a retainer ring for a port, wherein the bearing is sleeved on the gear shaft and is positioned by a shaft shoulder of the gear shaft; a bearing and a small assembly of the gear shaft are arranged in an inner hole of a power takeoff port gear; the bearing is positioned again by using a spigot in the inner hole; the retainer ring for the hole is arranged in a retainer ring groove of the inner hole of the power takeoff port gear so as to position the bearing and the gear shaft; and the assembled assembly is fixed on the torque converter casing by using the bolts and the gaskets. With the structure, the cantilever support type power takeoff mechanism is convenient to assemble and disassemble and has high efficiency and low cost.
Description
Technical field
The utility model relates to a kind of technical field of engineering machinery that is applied to, and relates in particular to the take-off that power is provided in the change-speed box.
Background technology
In the existing construction machinery and equipment change-speed box, provide takeoff output, generally all leave two take-off in order to give steering hydraulic system, hydraulic system of working.Take-off adopts identical structure, is made of the backup bearing at integral gear axle and gear wheel shaft two ends, and two bearings are supported on respectively on the casing and tor-con housing of change-speed box.This structure, high to the right alignment processing request of tor-con housing and casing bearing hole, the service life that when coaxiality error is big, can reduce bearing, influence the reliability of change-speed box, adopt two bearings simultaneously, process two bearing holes, production efficiency is low, the cost height.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of layout, and assembly and disassembly is convenient, efficient height, the cantilever support formula take-off that cost is low.
The purpose of this utility model is achieved in that this mechanism adopts cantilever design to replace existing simple beam structure.At first bearing carrier ring is on gear wheel shaft, utilize the shaft shoulder of gear wheel shaft that bearing is located, the little assembly of bearing and gear wheel shaft is packed in the endoporus of power taking ability to speak wheel, utilize the seam in the endoporus that bearing is located once more, packed in the circlip groove of power taking ability to speak wheel endoporus with back-up ring in the hole, with location bearing and gear wheel shaft, utilize bolt and spacers on the tor-con housing assembly that has assembled.
Because the utility model adopts said structure, has simplified processing technology, has increased substantially production efficiency, has prolonged the service life of bearing; Assembling and convenient disassembly are beneficial to maintenance; Use single bearing to reduce productive costs, reduced the deadweight of change-speed box.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
1 tor-con housing, 2 power taking abilities to speak wheel, 3 gear wheel shafts, 4 bolts, 5 pads, 6 bearings, 7 hole back-up rings among the figure.
The specific embodiment
Embodiment: a kind of cantilever support formula take-off comprises tor-con housing 1, power taking ability to speak wheel 2, gear wheel shaft 3, bolt 4, pad 5, bearing 6, hole back-up ring 7.At first bearing 6 is enclosed within on the gear wheel shaft 3, the shaft shoulder that utilizes gear wheel shaft 3 is with bearing 6 location, the little assembly of bearing 6 and gear wheel shaft 3 is packed in the endoporus of power taking ability to speak wheel 2, utilize the seam in the endoporus that bearing 6 is located once more, the hole is taken turns in the circlip groove of 2 endoporus with the back-up ring 7 power taking ability to speak of packing into, with location bearing 6 and gear wheel shaft 3, utilize bolt 4 and pad 5 to be fixed on the tor-con housing 1 assembly that has assembled.The utility model adopts said structure, has simplified processing technology, and assembling and convenient disassembly use single bearing to reduce productive costs, have reduced the deadweight of change-speed box.
Claims (1)
1. cantilever support formula take-off, form with back-up ring by tor-con housing, power taking ability to speak wheel, gear wheel shaft, bolt, pad, bearing, hole, it is characterized in that: bearing carrier ring is on gear wheel shaft, and in the endoporus of the power taking ability to speak of packing into wheel, pack into back-up ring in the circlip groove of power taking ability to speak wheel endoporus in the hole.
