Description
Technical field
The utility model belongs to auto parts apparatus technical field, particularly relates to a kind of deep hole spindle nose.
Background technique
Spindle nose is indispensable mechanical part in mechanical transmission course, has important effect in mechanical transmission course.When mechanical transmission, because the matching of structure and system is poor, in use often there is following defect in current spindle nose:
1, in transmission process, spindle nose driving force is uneven, and transmission effect is poor, and in transmission process, friction factor is comparatively large, and serious wear, affects working life, causes the replacement frequency of parts higher, cost increase.
2, existing spindle nose is connected insecure with other parts of system, effectively can not meet the requirement of join strength, even causes spindle nose in transmission process, occur the phenomenon come off.
So the structural design of above-mentioned spindle nose is unreasonable, spindle nose is made to there is larger problem.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of rational in infrastructure, can very well and other parts of system be connected firmly, can extend the deep hole spindle nose of its service time, its technological scheme is as follows:
Deep hole spindle nose, is characterized in that, described deep hole spindle nose comprises body, axis hole is offered in described body, described axis hole one end be opened in the front of the upper end of body, on the front of body upper end, welding is connected with hollow shaft sleeve pipe, and hollow shaft sleeve pipe and axis hole match; The sidepiece of described body upper end is provided with the arc-shaped recess portion of triangle, and the foot in the arc-shaped recess portion of triangle is provided with protuberance, passes through chamfered transition between protuberance and arc-shaped recess portion; The lower end of described body is the cascade column structure for installing connection bearing.
Optimal way is, the spacing between the minimum point in the arc-shaped recess portion of described triangle and shaft hole inner wall is 6-8cm.
The deep hole spindle nose that the utility model provides, when reality uses, is connected hollow shaft sleeve after the effect of axis hole matches with hollow shaft sleeve pipe.Hollow shaft sleeve pipe is in order to better and the connection of hollow shaft sleeve, make this device can very well and other parts of system be connected firmly.The arc-shaped recess portion of triangle makes spindle nose when in use, and can reduce friction between the miscellaneous part of system, extends its service time.The effect of protuberance is the intensity in order to strengthen spindle nose upper end side portion.
The beneficial effects of the utility model are: rational in infrastructure, can very well and other parts of system be connected firmly, its service time can be extended.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, deep hole spindle nose, described deep hole spindle nose comprises body 1, axis hole 2 is offered in described body 1, described axis hole 2 one end be opened in the front 3 of the upper end of body 1, on the front 3 of body upper end, welding is connected with hollow shaft sleeve pipe 4, and hollow shaft sleeve pipe 4 and axis hole 2 match; The sidepiece of described body 1 upper end is provided with the arc-shaped recess portion 5 of triangle, and the foot in the arc-shaped recess portion 5 of triangle is provided with protuberance 6, by inclined-plane 7 transition between protuberance 6 and arc-shaped recess portion 5; The lower end of described body 1 is the cascade column structure 8 for installing connection bearing.
Optimal way is, the spacing between the minimum point in the arc-shaped recess portion of described triangle and shaft hole inner wall is 6-8cm.
When concrete use, the effect of axis hole is connected hollow shaft sleeve after matching with hollow shaft sleeve pipe.Cascade column structure is then install bearing.The maximum model of current use is then the deep hole spindle nose of 16T.
