Abstract
The invention relates to a shaft end holding cap which comprises a cylinder part, wherein the cylinder part is provided with a closed axial end part and an open axial end part; and a cap peak-shaped flange is extended radially outwards from the open axial end part of the cylinder part, wherein the two opposite sides of the cap peak-shaped flange are cutting planes. The shaft end holding cap of the invention can be applied to a motor with worm and worm gear transmission output, simultaneously controls a worm to axially and radially play, performs the functions of supporting and lubricating the axial direction and the radial direction of the shaft end, and has low cost, simple structure, convenient assembly and easy mass production.
Description
Technical field
The present invention relates to a kind of shaft end holding cap, refer to a kind of being applied to especially with the shaft end holding cap in the motor of Worm and Worm Gear Driving output.
Background technology
At present, the worm shaft end that is applied to motor supports, the parts of lubrication are broadly divided into two kinds: a kind of for the axle head pad, as shown in Figure 4; Dispose an axle head pad 40 in axle 30 ends and realize axial endplay control, still, the axle head pad does not have the diameter of axle to control; Then axle 30 radial force when transmission can cause bending to influence transmission accuracy, thereby possibly produce motor noise and self-locking property, particularly under the situation of small diameter shaft; Because of its undercapacity, influence particularly evident; If realize axial endplay control through the axle head pad of selecting different-thickness in addition, then increase the specification of part and cause changeing the complexity of joining; Another kind of for to add a journal bearing outside the axle head pad in addition preceding a kind of the application, it can be controlled respectively axle is radial and axial simultaneously, and is expensive but its part increases, and assemble also quite trouble, even efficient is very low in batch process.
Summary of the invention
Because above-mentioned existing axle head supports the deficiency of lubricating component, the technical problem that solve is: provide a kind of cost low, simple in structure, be convenient to assembling, the radial and axial axle head of Control Shaft simultaneously that is easy to produce in enormous quantities supports lubricating component.
For solving the problems of the technologies described above; The present invention provides a kind of shaft end holding cap; Comprise a cylindrical portion, this cylindrical portion has the axial end portion of axial end portion and another opening of a sealing, from the opening axial end portion of the said cylindrical portion the brim of a hat shape flange that extended radially outwardly; Wherein, the both sides that said the brim of a hat shape flange is relative are for scabbling face;
The outer surface center of the sealing axial end portion of said cylindrical portion axially is outward extended with an axle head jut, and said axle head jut place is equipped with a circular elastic component, and described axle head jut is the cylindrical of a projection;
Said shaft end holding cap is processed by polyamide 46;
And the axle head jut of said shaft end holding cap can be used by sheathed this circular elastic component.
Below in conjunction with accompanying drawing and embodiment the present invention is done detailed description further:

Fig. 2 is a upward view of the present invention;
The cutaway view that Fig. 3 cooperates an elastic component to use for the present invention; And
Fig. 4 is existing axle head pad.
Embodiment
As shown in Figure 1; Shaft end holding cap 10 of the present invention has the shape of similar cap; It comprises a cylindrical portion 11; This cylindrical portion 11 has the axial end portion of axial end portion and another opening of a sealing, from the opening axial end portion of the said cylindrical portion the brim of a hat shape flange 12 that extended radially outwardly, is columniform axle head jut 13 and axially be outward extended with one in the outer surface center of the sealing axial end portion of cylindrical portion; Cylindrical portion 11 offers a passage 14 with the brim of a hat shape flange 12 centers, and the worm screw of power supply machine inserts used; Said shaft end holding cap is processed by polyamide 46 (being PA46), and its intensity and resistance to wear provide support and the lubricating function of the present invention to axle head.
As shown in Figure 2, the relative both sides of the brim of a hat shape flange 12 are arranged in the motor for scabbling face, can prevent that shaft end holding cap 10 from following worm-drive and axially revolution.
As shown in Figure 3, shaft end holding cap of the present invention can cooperate elastic component to use together, sheathed one circular elastic component 20 on axle head jut 13; When the motor worm transmission, axle head jut 13 is main stress point, because of it has born most of power, thereby avoids elastic component 20 pressurizeds to overrun and distortion excessively; Simultaneously, elastic component 20 is sheathed on the axle head jut 13, the power that is delivered on the axle head jut 13 is cushioned, and the gap that compensation produces because of assembling in the scope of certain force, and compensation is because of the gap of axle head jut 13 losses generation.
Claims (3)
1. a shaft end holding cap is characterized in that, comprises a cylindrical portion; This cylindrical portion has the axial end portion of a sealing and the axial end portion of another opening; From the opening axial end portion of the said cylindrical portion the brim of a hat shape flange that extended radially outwardly, wherein, the relative both sides of said the brim of a hat shape flange are for scabbling face; The outer surface center of the sealing axial end portion of said cylindrical portion axially is outward extended with an axle head jut, and said axle head jut place is equipped with a circular elastic component.
2. shaft end holding cap according to claim 1 is characterized in that, said axle head jut is the cylindrical of a projection.
3. shaft end holding cap according to claim 1 is characterized in that said shaft end holding cap is processed by polyamide 46.
