Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of buffer gear.
Background technique
In existing mechanical equipment, usually realize the functions such as connection, transmission by axis, axis during the work time, usually
It will receive the power from axial direction, the stress intensity of axis is limited, and often force side and axis are hard contacts, in long-term stress
Under state, axis can be damaged, and leverage the service life of axis.
In conclusion in order to solve above-mentioned axis, needs to design one kind and be hardly damaged and service life
It is longer.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, to propose one kind and be hardly damaged and use
It lasts a long time.
The purpose of this utility model can be realized by the following technical scheme: a kind of buffer gear, including
Main shaft, it is axial to be arranged；
Axle sleeve, is sheathed on outside main shaft and main shaft one end is stretched out outside axle sleeve；
Spring is sheathed on main shaft and is located at main shaft and shaft room, and spring one end is against on main shaft, the other end and axle sleeve
It is fixed；
Attachment base is arranged and is connected with outside axle sleeve and with axle sleeve；
When main shaft is located at one end stress outside axle sleeve, the main shaft can opposite axle sleeve and attachment base axial movement.
In a kind of above-mentioned buffer gear, described axle sleeve one end is provided with mounting hole, is provided in the mounting hole and axis
The adjustment seat of external threading connection, the main shaft run through adjustment seat, and the spring other end is against in adjustment seat.
In a kind of above-mentioned buffer gear, one end outer surface that main shaft stretches out axle sleeve is convexly equipped with spacing collar, covers on main shaft
Equipped with rubber base and rubber base is against on spacing collar.
Compared with prior art, the utility model has the following beneficial effects:
In the utility model, by the way that axle sleeve is arranged outside main shaft, and spring is set between axle sleeve and main shaft, when main shaft stress
Power can be transferred on spring, play the role of buffering main shaft, avoid main shaft and force side hard contact, be effectively protected
Main shaft is not damaged, substantially prolongs the service life of main shaft.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
In figure, 10, main shaft；11, spacing collar；20, axle sleeve；21, mounting hole；30, spring；40, attachment base；50, adjustment seat；
60, rubber base.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, a kind of buffer gear of the use of the new type, including main shaft 10, axle sleeve 20, spring 30 and attachment base
5040。
The axial setting of main shaft 10, axle sleeve 20 is sheathed on outside main shaft 10 and axle sleeve 20 is stretched out outside in 10 one end of main shaft and can be with force
End in contact, spring 30 are sheathed on main shaft 10 and between main shaft 10 and axle sleeve 20, and 30 one end of spring is against on main shaft 10, another
End is fixed with axle sleeve 20, and attachment base 5040 is arranged outer with axle sleeve 20 and is connected with axle sleeve 20, which is used for and machinery
Other components of equipment are connected, and when main shaft 10 is located at one end stress outside axle sleeve 20, the main shaft 10 can opposite axle sleeve 20
It is moved axially with attachment base 5040.
When work, main shaft 10 stretches out one end stress of axle sleeve 20, so that main shaft 10 is moved axially with respect to axle sleeve 20, in spring
Under the action of 30, power is transferred on spring 30 by main shaft 10, is played the role of buffering main shaft 10, is avoided main shaft 10 and force
Hard contact is held, effectively protects that main shaft 10 is not damaged, substantially prolongs the service life of main shaft 10.
On the basis of the said structure, the utility model has been made it to be further improved and refined.
As shown in Figure 1, described 20 one end of axle sleeve is provided with mounting hole 21, it is provided in the mounting hole 21 and 20 spiral shell of axle sleeve
The adjustment seat of line connection, the main shaft 10 run through adjustment seat, and 30 other end of spring is against in adjustment seat.
Adjustment seat is threadedly coupled with axle sleeve 20, can adjust the relative position of adjustment seat and axle sleeve 20, to reach adjusting bullet
The purpose of the initial length of spring 30 meets different buffer requirements with the initial precompressed amount of adjustment spring 30.
As shown in Figure 1, one end outer surface that main shaft 10 stretches out axle sleeve 20 is convexly equipped with spacing collar 11, it is arranged on main shaft 10
Rubber base 60 and rubber base 60 is against on spacing collar 11.
Rubber base 60 plays the buffer function of auxiliary, the hard contact of main shaft 10 Yu force side is further avoided, to master
The force side of axis 10 plays a protective role, and spacing collar 11 plays position-limiting action to rubber base 60, can prevent 60 stress of rubber base
It is moved on main shaft 10 afterwards, improves the stability of rubber base 60.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
