Abstract

The invention relates to a worm-and-bearing integrated assembly for a vehicle, which comprises a worm, wherein the outer wall of an installation portion on one end of the worm is processed to be an arc-shaped roll way along the circumference of the worm; a steel ball is mounted in the roll way through a maintaining frame and an outer ring of a bearing; and a seal ring is mounted between the outer wall of the installation portion and the outer ring of the bearing. According to the invention, an inner ring of the bearing is directly molded on an end portion of the worm so as to avoid assembly deviation; the assembly operation of the worm is simplified; the pressing process is not needed; and installation parts and a positioning device of an end face of the bearing are reduced.

Description

Automobile worm bearing integrated component
Technical field
The present invention relates to technical field of automobile parts, particularly relate to the mounting technology of automobile worm screw and bearing.
Background technique
Turbine and worm transmission belongs to driving mechanism very common in machinery industry, in the field of turbine and worm transmission application, is applied to exigent transmission accuracy in automobile industry, is particularly applied in EPS commutator.As shown in Figure 1, worm screw two ends are fixed by bearing, one end is fixed end, the other end is free end, fixed end needs Bearing inner play to ensure turbine and worm flank engagement position and precision, the requirement that needs are very high is coordinated to bearing and internal control, very high requirement is also needed to the play of bearing simultaneously.But at present, be no matter the bearing of how high machining accuracy, there is mismatch error all the time, be difficult to the high occasion that meets the demands.
Summary of the invention
The applicant, for existing technology above shortcomings, carries out studying and designing, and develop a kind of automobile worm bearing integrated component, it adopts the integrative-structure of worm screw and bearing, efficiently avoid alignment error, improves installation quality.
The technical solution adopted in the present invention is as follows:
A kind of automobile worm bearing integrated component, comprise worm screw, the outer wall of the assembly department of worm screw one end is processed into arcuate groove along its circumference, installs steel ball, be provided with seal ring between the outer wall of assembly department and bearing outer ring in raceway by retainer, bearing outer ring.
Further improvement as technique scheme:
The outer wall of described assembly department, with bulge loop, bulge loop is processed into described raceway, is positioned at the bilateral symmetry of raceway with the installation annular groove installing seal ring.
Beneficial effect of the present invention is as follows:
In the present invention, the assembly department of worm screw processes raceway, running in bearings outer ring, seal ring, steel ball and retainer, form overall structure, ensure Bearing inner gap width, according to installation conditions, without the need to considering the impact of the fit dimension of brearing bore and axle on Bearing inner gap, thus improve the conformity of installing, improve the quality of integral installation.Owing to directly generating raceway, thus save bearing face positioning device, minimizing installation step.
Bearing inner race is molded directly within worm end by the present invention, avoids assembly error; Simplifying the assembly manipulation of worm screw, without the need to press-fiting operation, reducing the positioning device of mounting parts and bearing face.
Accompanying drawing explanation
Fig. 1 is the mounting structure figure of existing worm screw and bearing.
Fig. 2 is structural drawing of the present invention.
In figure: 1, worm screw; 11, assembly department; 12, raceway; 13, bulge loop; 14, annular groove is installed; 2, retainer; 3, bearing outer ring; 4, steel ball; 5, seal ring.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 2, the automobile worm bearing integrated component of the present embodiment, comprise worm screw 1, the outer wall of the assembly department 11 of worm screw 1 one end is processed into arcuate groove 12 along its circumference, by retainer 2, bearing outer ring 3, steel ball 4 is installed in raceway 12, between the outer wall of assembly department 11 and bearing outer ring 3, seal ring 5 is installed.
The outer wall of assembly department 11, with bulge loop 13, bulge loop 13 is processed into raceway 12, is positioned at the bilateral symmetry of raceway 12 with the installation annular groove 14 installing seal ring 5.
In the present invention, the assembly department 11 of worm screw 1 processes raceway 12, running in bearings outer ring 3, seal ring 5, steel ball 4 and retainer 2, form overall structure, ensure Bearing inner gap width, according to installation conditions, without the need to considering the impact of the fit dimension of brearing bore and axle on Bearing inner gap, thus improve the conformity of installing, improve the quality of integral installation.Owing to directly generating raceway 12, thus save bearing section positioning device, minimizing installation step.
Bearing inner race is molded directly within worm end by the present invention, avoids assembly error; Simplifying the assembly manipulation of worm screw, without the need to press-fiting operation, reducing the positioning device of mounting parts and bearing face.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
