Abstract
The utility model relates to the technical field of steering gears, in particular to a connecting structure of a dust cover and a shell of a steering gear. The connecting structure of the dust cover and the shell of the steering gear comprises the shell, the dust cover and a clamping hoop, and is characterized in that the upper end and the lower end of the shell are respectively provided with a double narrow groove, the dust cover is arranged outside the double narrow grooves, the clamping hoop is arranged outside the dust cover, and the dust cover is in close fit with the clamping hoop. Compared with the prior art, the function of connecting the dust cover with the shell is achieved, lower machining cost of the shell is guaranteed, corrosion resistance of a sealing surface is improved, and it is guaranteed that the inclination problem cannot be caused. The left groove and the right groove are designed, assembly stability of the dust cover is improved, and a contact surface with two supporting points is provided, so that inclination is not prone to occurring during assembly. In addition, according to the connecting structure, only local features of the blank of the shell are modified, and no extra machining cost needs to be added.
Description
Technical field
The utility model relates to steering box technical field, specifically the connection structure of a kind of steering box dust boot and housing.
Background technology
In order to prevent ambient impurities or moisture intrusion steering box, between dust boot and housing, need to seal, also need to guarantee to be not easy to come off from housing after dust boot is installed simultaneously.
Traditional housing is covered with two kinds of designs with dustproof:
The first designs as shown in Figure 1, and the first housing 11 end surface are processed with a wide groove, and groove coordinates with the first dust boot 12 end features, and top clamps by the first clamp 13, realizes sealing.The groove surfaces both sides of processing are slightly high projection.Can prevent from sliding or coming off along housing after the first dust boot 12 from installing.This design can be good at realizing the function and the object that connect, but the first housing 11 adds man-hour and processes for the wide groove surface sealing except needs, also need the chamfering of machined grooves both sides, time-consuming and need to use manyly process tool or complex cutting tool in processing, cost is higher.In addition, it is outside face lowest part that the first housing 11 is processed sealing surface, easily gathers environmental pollution impurity or moisture, and sealing surface is caused to corrosion, affects sealing property.
The second designs as shown in Figure 2, it has suitably improved sealing surfaces height, remove projection and the chamfering of sealing surfaces both sides, the substitute is, be designed with a narrow groove in sealing surfaces front, by on the second dust boot 22 with the design of groove fit feature, make the second dust boot 22 can realize axial limiting.The second housing 21 sealing surfaces and the second dust boot 22 tops are used the second clamp 23 to clamp.Because preposition groove does not seal, therefore can realize by Blank Design, without processing, this design has solved the part existing problems that design 1.But but caused another problem of fitting process, because axial limiting groove is narrower, it contacts close to line with dust boot projection mating feature, in the time of assembling, easily makes dust boot tilt, and needs extra care, easily causes and does over again or affect efficiency of assembling.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, in realizing dust boot and housing linkage function, had both guaranteed lower housing tooling cost, improved sealing surface corrosion stability, guaranteed again can not cause the tilt problem in assembling.
For achieving the above object, design the connection structure of a kind of steering box dust boot and housing, comprise housing, dust boot, clamp, it is characterized in that: be respectively equipped with two narrow grooves at the two ends up and down of housing, two narrow grooves are provided with dust boot outward, dust boot is provided with clamp outward, and dust boot and clamp are for closely cooperating.
Described dust boot and the cooperation place of housing are biconvex structure.
Two projections of two of described housing two narrow grooves and dust boot are for closely cooperating.
The utility model compared with the existing technology, in realizing dust boot and housing linkage function, had both guaranteed lower housing tooling cost, improved sealing surface corrosion stability, guaranteed again can not cause the tilt problem in assembling.Design left and right two grooves, improved imitative dust boot Assembly stability, had two fulcrum contact surfaces, when assembling, be not easy run-off the straight.In addition, casing blank local feature has just been revised in this design, without increasing additional processing cost.

Fig. 2 is the structural representation of traditional the second design.
Fig. 3 is the utility model structural representation.
Referring to Fig. 1,11 is the first housing, and 12 is the first dust boot, and 13 is the first clamp.
Referring to Fig. 2,21 is the second housing, and 22 is the second dust boot, and 23 is the second clamp.
Referring to Fig. 3,31 is housing, and 32 is dust boot, and 33 is clamp, and 34 is two narrow grooves.
The specific embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, the first housing 11 end surface are processed with a wide groove, and groove coordinates with the first dust boot 12 end features, and top clamps by the first clamp 13, realize sealing.The groove surfaces both sides of processing are slightly high projection.Can prevent from sliding or coming off along housing after the first dust boot 12 from installing.This design can be good at realizing the function and the object that connect, but the first housing 11 adds man-hour and processes for the wide groove surface sealing except needs, also need the chamfering of machined grooves both sides, time-consuming and need to use manyly process tool or complex cutting tool in processing, cost is higher.In addition, it is outside face lowest part that the first housing 11 is processed sealing surface, easily gathers environmental pollution impurity or moisture, and sealing surface is caused to corrosion, affects sealing property.
As shown in Figure 2, suitably improve sealing surfaces height, removed projection and the chamfering of sealing surfaces both sides, the substitute is, be designed with a narrow groove in sealing surfaces front, by the second dust boot 22 with the design of groove fit feature, make the second dust boot 22 can realize axial limiting.The second housing 21 sealing surfaces and the second dust boot 22 tops are used the second clamp 23 to clamp.Because preposition groove does not seal, therefore can realize by Blank Design, without processing, this design has solved the part existing problems that design 1.But but caused another problem of fitting process, because axial limiting groove is narrower, it contacts close to line with dust boot projection mating feature, in the time of assembling, easily makes dust boot tilt, and needs extra care, easily causes and does over again or affect efficiency of assembling.
As shown in Figure 3, be respectively equipped with two narrow grooves 34 at the two ends up and down of housing 31, the outer dust boot 32 that is provided with of two narrow grooves 34, dust boot 32 is outer is provided with clamp 33, and dust boot 32 with clamp 33 for closely cooperating; Dust boot 32 is biconvex structure with the cooperation place of housing 31; Two of housing 31 two narrow grooves 34 with two projections of dust boot 32 for closely cooperating.
Compared with current design, the utility model has designed two narrow grooves 34 on housing 31, on the corresponding fitting surface of dust boot 32, has designed biconvex structure, has improved dust boot 32 Assembly stabilities, has two fulcrum contact surfaces, is not easy run-off the straight when assembling.In addition, housing 31 blank local features have just been revised in this design, without increasing additional processing cost.
