Abstract
A special wrench for pushing a rear wheel hub bearing is characterized in that the special wrench is composed of a screw rod, a sleeve and a 1/2 '' interface sleeve. The front of the screw rod is processed into a nut 1. The excircle part on the top of the sleeve is processed into two planes symmetrical to each other bilaterally. The central position of the top is processed into female threads and forms a nut 2. The sleeve and the screw rod are assembled together. After the end of the screw rod is locked by double nuts, the top of the sleeve is welded with the 1/2 '' interface sleeve. The special wrench in the utility model effectively guarantees that the sleeve and the wheel hub bearing unit will generate no radial position accuracy deviation due to the gravity after the wheel hub bearing unit sleeves the sleeve and no verticality deviation of the sleeve axial line relative to the bearing inner ring pressure working face and no position accuracy deviation of the wheel hub bearing unit on the radial direction of the sleeve will be generated. Meanwhile, the pressure can be fully ensured to be uniformly performed on the end face of the bearing inner ring during a pushing process. The inner diameter and the shaft are guaranteed not to damage each other. The special wrench in the utility model has the characteristics of small figure, lightness, high efficiency and safe as well as portable operation.
Description
Technical field
The utility model belongs to the technical field that vehicle is debug the special tooling jig, and particularly a kind of rear wheel hub bearing is pressed into special spanner.
Background technology
Owing in the dust blocking tray of A130 type car rear brake and the bottom surface of the hub-bearing unit distance 7mm is arranged.So, must with bolt dust blocking tray and hub spindle be fastened on the rear axle earlier in the assembling process; Again hub-bearing unit is pressed into hub spindle; Assemble other parts.
But be interference fit between hub spindle and bearing unit, and bearing inner race is positioned at wheelboss flange centre bore inside.Usually line production all adopts special purpose machine tool to press-fit.Trial-production exploitation and after-sales service then do not have such condition.The latter often adopts hammering method.But the employing hammering method, because bearing inner race is positioned at wheelboss flange centre bore inside, percussion power can't evenly pass to bearing inner race.Will certainly cause the bearing inner race and the generation of axle to tilt, cause the surface damage of bearing inner race or axle simultaneously, thereby the directly assembly precision and the service life of influence spool and bearing improve percent defective greatly.
Summary of the invention:
The purpose of this utility model is to provide a kind of rear wheel hub bearing to be pressed into special spanner.
The technical solution of the utility model is achieved in that
Rear wheel hub bearing is pressed into special spanner, it is characterized by: it is by leading screw, and sleeve, 1/2 " form; the leading screw front end is processed into a nut A; cylindrical place, sleeve top processes symmetrical two planes, and internal thread of top center position processing forms nut B by the interface sleeve.Sleeve and leading screw are assembled together, and at the terminal double nut locking of installing of leading screw, sleeve top welding 1/2 " interface sleeve.
The utility model has effectively guaranteed after hub-bearing unit is sleeved on the sleeve, the not reason gravity effect and produce radial position degree deviation of sleeve and hub-bearing unit, and the axis of sleeve with respect to the perpendicularity deviation of bearing inner race pressure acting surface and hub-bearing unit in position degree deviation that sleeve directly makes progress.Simultaneously, can also fully guarantee in process of press in pressure can stepless action on the end face of bearing inner race and internal diameter does not damage mutually with axle.Have the advantages that profile is little, in light weight, efficient is high, handling safety is light.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, rear wheel hub bearing is pressed into special spanner, it is characterized by: it is by leading screw 1 sleeve 2,1/2 " interface sleeve 3 is formed; the front end of leading screw 1 is processed into a nut A; the cylindrical place, top of sleeve 2 processes symmetrical two planes, and internal thread of top center position processing is nut B, and sleeve 2 and leading screw 1 are assembled together; and after the end of leading screw 1 is used double nut 4 lockings, top welding 1/2 " the interface sleeve 3 of sleeve 2.
Embodiment:
The utility model length overall 200mm; External diameter φ 50mm; Heavy 2kg; Leading screw 1 screws out back total length 250mm fully.
1, with hand screw out left leading screw 1 to rim of a cup 5 farthest of sleeve 2.
2, the rear wheel hub bearing unit is enclosed within on this spanner, 1 front end nut A is exposed to outside the bearing unit with leading screw.
3, with hand leading screw 1 front end nut A is revolved and on the screw thread of rear drum axle.
4, with pneumatic impact spanner or hand-operated tools sleeve 2 is screwed, along with the displacement of sleeve 2 on leading screw 1, hub-bearing unit is pressed into hub spindle accurately, evenly, reposefully.
5, oppositely unscrew sleeve 2, along with unscrewing of sleeve 2, leading screw 1 front end nut A also gets loose from hub spindle thereupon.
6, check: bearing is pressed on the hub spindle reposefully, and bearing surface does not have any damage, and the bearing assembly precision is guaranteed.
