Abstract

The utility model discloses a bearing and shaft assembly structure. The structure comprises a step shaft, wherein the shaft end of the step shaft comprises a first step and a second step; an outer thread is lathed on the second step, two nuts which are closely arranged are screwed on the second step; a bearing is sleeved on the first step, and the right end face of the bearing props against the left end face of the internal nut; a withdrawal sleeve is sleeved in a gap between the bearing and the first step, and the section of the withdrawal sleeve is conical; a gland is arranged at the end part of the withdrawal sleeve; a locking bolt extending into the end face of the step shaft is arranged at the left end face of the gland in a screwed manner. The bearing and shaft assembly structure is simple in structure design, and the withdrawal sleeve is matched with the nuts, so that the bearing can be easily tightened on the shaft; furthermore, the contact firmness of the bearing in the withdrawal sleeve can be guaranteed due to the design of anti-skid texture, skidding is prevented, the whole structure is reasonable in design, and the shaft and the bearing can be assembled and disassembled conveniently.

Description

The assembly structure of a kind of bearing and axle
technical field:
The utility model relates to the assembly structure of a kind of bearing and axle.
background technique:
The mounting type of bearing and axle is to be directly installed on axle mostly, important or large size bearing is generally arranged on axle by adapter sleeve, it is easy that band adapter sleeve bearing is installed tensioning, but adapter sleeve is come loose during dismounting, then bearing is struck down, often be subject to inner part impact, do not make power, bearing is difficult to be removed, and sometimes only has and adopts destructive dismounting, cause components damage, it is poor that bearing is installed rear stability.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide the assembly structure of a kind of bearing and axle, and reasonable in design can guarantee the connective stability between bearing and axle, conveniently mounts and dismounts.
The technical solution of the utility model is as follows:
The assembly structure of bearing and axle, comprise Step Shaft, it is characterized in that: the axle head of described Step Shaft comprises first step, second step, the described second step outside thread of having got on the bus, on second step, be combined with two nuts that are adjacent to together, on described first step, be set with right side and withstand the bearing of inner screw nut left side, on gap between bearing and first step, be set with withdrawal sleeve, withdrawal sleeve cross section is taper, described withdrawal sleeve end is provided with gland, screws the lock bolt that stretches into Step Shaft end face is installed on gland left side.
Described bearing and the assembly structure of axle, is characterized in that: the outer wall of described withdrawal sleeve is provided with anti-slip veins, and anti-slip veins is reticulate pattern.
The utility model has the advantages that:
The utility model structural design simple that, by withdrawal sleeve attaching nut, make bearing is easy tensioning on axle, meanwhile, the design of anti-slip veins guarantees the soundness that bearing contacts between withdrawal sleeve, is difficult for skidding, overall construction design is reasonable, makes installation and removal between axle and bearing become convenient.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1:
The assembly structure of bearing and axle, comprise Step Shaft, the axle head of Step Shaft comprises first step 1, second step 2, second step 2 outside thread 3 of having got on the bus, on second step 2, be combined with two nuts 4 that are adjacent to together, on first step 1, be set with right side and withstand the bearing 5 of inner screw nut left side, on gap between bearing 5 and first step 1, be set with withdrawal sleeve 6, withdrawal sleeve 6 cross sections are taper, withdrawal sleeve 6 ends are provided with gland 7, on gland 7 left sides, screw the lock bolt 8 that stretches into Step Shaft end face is installed, prevent withdrawal sleeve play laterally.
The outer wall of withdrawal sleeve 6 is provided with anti-slip veins 9, and anti-slip veins 9 is not for skidding between reticulate pattern assurance and bearing, and stability improves.

Claims (2)
