Abstract

The utility model relates to a bearing gap fixator. The bearing gap fixator comprises a fixing nut, a disc chuck and bolts, wherein the disc chuck and the bolts are used to fix the gap between a bearing and the fixing nut. The bearing gap fixator is characterized in that the fixing nut is provided with a first screw hole, a second screw hole and a third screw hole, wherein the diameter of the first screw hole is larger than that of the second screw hole, the disc chuck is provided with a screw hole I, a screw hole II and a screw hole III which correspond to the first screw hole, the second screw hole and the third screw hole in position and in diameter, and the disc chuck is fixed on the bearing through a clamping pin. When the three screws holes in the fixing nut correspond to the screw holes in the disc chuck, the fixing nut and the disc chuck are fixed through the bolts, the fixing nut is prevented from rotating and loosing, the gap between the bearing and the fixing nut keeps unchanged when a car runs, and therefore normal operation is guaranteed. The bearing gap fixator is simple in structure and convenient to use.

Description

The bearing play fixture

Technical field

The utility model relates to a kind of automobile bearing gap fixture.

Background technique

In the at present automobile bearing assembling, utilize the nut screw thread to screw to be fixed and to lock, but automobile in the process of moving, produce vibration, easily make nut produce the auto back pine, so that the normal clearance between nut and the bearing disappears excesssive gap, hub assembly is easily dished out, cause potential safety hazard, if the tension that nut revolves in assembling, the bearing play is too small, power transmission is improper, automobile in the process of moving, the bearing expansion of easily generating heat, the too small so that motor output in gap is obstructed, easily suppress machine, cause that engine mission damages too early, brake power is unequal, and fuel oil is insufficient, engine power is not enough, and component damage too early.

Summary of the invention

This practicality is used for the uppity problem in bearing play, provides a kind of bearing play fixture, so that bearing and floral disc gap remain unchanged.

For achieving the above object, the technological scheme that adopts of the utility model is:

A kind of bearing play fixture, comprise hold-doun nut, be used for floral disc and the bolt in rigid bearing and hold-doun nut gap, be provided with the first screw, the second screw and the 3rd screw on the described hold-doun nut, wherein the first screwhole diameter is greater than the second screwhole diameter, is provided with screw I, screw II and the screw III corresponding with the position of the first screw, the second screw and the 3rd screw and diameter on the described floral disc.

Described hold-doun nut front is provided with the gradient.

Described the first screw, the second screw and the 3rd screw evenly are arranged on the hold-doun nut, and three screw central shafts distance equates.

The utility model arranges a large screw and two little screws at hold-doun nut, also be provided with three positions and the corresponding screw of diameter on the floral disc, in the automobile bearing assembling, install first hold-doun nut, set the gap of bearing and hold-doun nut, floral disc is installed again, floral disc is fixed on the bearing by bayonet lock, when three screws on the hold-doun nut are corresponding with the screw on the floral disc, by bolt hold-doun nut and floral disc is fixed, so that hold-doun nut can not rotate back to pine, in the automobile running, bearing and hold-doun nut gap remain unchanged, and guarantee normal operation, the utility model is simple in structure, and is easy to use.

Fig. 2 is the utility model disc chuck structure schematic diagram.

Embodiment

Such as Fig. 1, shown in Figure 2, a kind of bearing play fixture, comprise hold-doun nut 1, the floral disc 5 and the bolt that are used for rigid bearing and hold-doun nut gap, be provided with the first screw 2 on the hold-doun nut 1, the second screw 3 and the 3rd screw 4, wherein the first screw 2 diameters are greater than the second screw 3 diameters, be provided with the screw I 6 corresponding with the first screw 2 positions and diameter on the floral disc 5, with the second screw 3 positions and the corresponding screw II 7 of diameter, the screw III 8 corresponding with the position of the 3rd screw 4 and diameter, hold-doun nut 1 and floral disc 5 are by fixing with the corresponding bolt of screw; Hold-doun nut 1 front is provided with the gradient, is convenient to respectively positive and negative, guarantees that hold-doun nut 1 correctly installs; The first screw 2, the second screw 3 and the 3rd screw 4 evenly are arranged on the hold-doun nut 1, and three screw central shafts distance equates, so that hold-doun nut 1 is stressed even, increase the service life; The first screw 2 diameters are greater than the second screw 3 diameters; the 3rd screwhole diameter can equate with the first screwhole diameter or the second screwhole diameter; also can be all unequal; the diameter of three screws on the hold-doun nut 1 is entirely not identical; thereby the diameter of three corresponding screws is entirely not identical yet on the floral disc 5; when hold-doun nut 1 is suitable with the gap of bearing; guarantee that floral disc 5 and the mounting type of hold-doun nut 1 only have a kind of; namely only have corresponding screw on three screws and the hold-doun nut 1 on the floral disc 5 at once, could be with corresponding bolt that floral disc 5 is fixing with hold-doun nut 1.

When the utility model uses, first hold-doun nut 1 is installed on the bearing, again floral disc 5 is installed in the draw-in groove of bearing by the bayonet lock 9 on the floral disc 5, hold-doun nut 1 revolution, so that hold-doun nut 1 is normal with the bearing play, three corresponding screws on three screws on this moment hold-doun nut 1 and the floral disc are corresponding, by corresponding bolton, so that hold-doun nut 1 can not become flexible, guaranteed that the gap of hold-doun nut 1 and bearing immobilizes, guarantee safe operation.

Claims
