Abstract
The utility model discloses an output shaft bearing supporting structure which comprises an output shaft 1 and a front end conical roller bearing 2. The front end conical roller bearing 2 is arranged at the front end of the output shaft 1 in a sleeved mode. The front end of the output shaft 1 is an output end 1a. The back end of the output shaft 1 is provided with a back end cylindrical roller bearing 3 in a sleeved mode, the middle portion of the output shaft 1 is provided with a middle conical roller bearing 4 in a sleeved mode, the middle conical roller bearing 4 and the front end conical roller bearing 2 are placed on the front side and the back side of the output end 1a of the output shaft 1, the middle conical roller bearing 4 and the front end conical roller bearing 2 are opposite in cone oblique direction, and the outer side of the middle conical roller bearing 4 is fixedly provided with a middle bearing pressing disc assembly 5 in a sleeved mode. According to the output shaft bearing supporting structure, original front-back-end conical bearing supporting is changed into front end and middle conical bearing and back end cylindrical bearing supporting, so that stress borne by the output shaft is fully absorbed, meanwhile, the structure has the advantages of being convenient to mount and low in transforming cost, and potential safety hazards are reduced.
Description
Technical field
The utility model relates to gearbox field, particularly relates to the bearing support structure of output shaft in a kind of gearbox.
Background technique
Gearbox mainly refers to the gearbox of automobile, and it is divided into manual, automatic two kinds, and manual transmission is mainly made up of gear and input shaft, output shaft etc., produces variable-speed torque-converting by different Gear combination.Output shaft is the axle of output torque in gearbox, by being solidly set on gear and the common transferring power of input shaft on it.At present output shaft is on the market all that tapered roller bearing by be set with the opposite direction that tilts in rear and front end supports output shaft jointly, and bears in the axial direction stressed of output shaft and radially stressed.Lasting stressed excessively of a specified duration when output shaft, can, in output shaft middle part accumulation radial stress, go down for a long time, cause output shaft easily from Central Cracking, have a strong impact on the installation quality of gearbox.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of output shaft supporting structure that solves output shaft middle part cumulative stress.
The technical solution of the utility model is as follows: a kind of output shaft bearing supporting structure, comprise output shaft (1), and be sleeved on the nose circle taper roller bearing (2) of output shaft (1) front end, be output terminal (1a) at the front end of this output shaft (1), described output shaft (1) rear end is set with rear end roller bearing (3), the middle part of this output shaft (1) is also set with middle circle taper roller bearing (4), described middle circle taper roller bearing (4) and nose circle taper roller bearing (2) lay respectively at the both sides, front and back of the upper output terminal (1a) of output shaft (1), the circular cone true dip direction of this middle circle taper roller bearing (4) and nose circle taper roller bearing (2) is contrary, and this middle circle taper roller bearing (4) outside is installed with intermediate bearing platen assembly (5).
Use said structure to support output shaft, because most of stress is all accumulated in the output terminal of output shaft, in the both sides, front and back of output terminal, two tapered roller bearings that true dip direction is contrary are set, because having plane of inclination, tapered roller bearing can limit output shaft run-out, while, two tapered roller bearings laid respectively at the both sides, front and back of output terminal, can fully dissolve the cumulative stress being accumulated on output shaft, then be set with roller bearing in the rear end of output shaft and be used for supporting output shaft, make the running of output shaft more steady.
Described intermediate bearing platen assembly (5) is circular, the endoporus of this intermediate bearing platen assembly (5) has flange (5a), and this intermediate bearing platen assembly (5) is solidly set on by flange (5a) on the outer circumferential face of middle ball roller bearing (4), evenly be equipped with at least three bearing plate bolts (6) at the annular surface of described intermediate bearing platen assembly (5), the termination of this bearing plate bolt (6) is towards output shaft (1) front end.Adopt the intermediate bearing platen assembly structure of said structure, middle circle taper roller bearing is sleeved on output shaft, then middle circle taper roller bearing outer ring is fixed in the center hole of intermediate bearing platen, then intermediate bearing platen is fixedly connected in gear box casing by bearing plate bolt.
Beneficial effect: the utility model changes the support of original front end and back end cone bearing into front end and middle cone bearing, rear end cylindrical bearing support, the stress being born fully to absorb output shaft, also have be simultaneously convenient to install, reforming cost is low and reduce the feature such as potential safety hazard.
