Abstract
The utility model discloses a kind of quarry tipper tapered expansion pin, including taper bearing pin, tapered sleeve, pad, bolt, tapered sleeve, pad, bolt are successively set on taper bearing pin both sides, and tapered sleeve, pad are sleeved on bolt, taper bearing pin is provided at both ends with screwed hole, and bolt is arranged in screwed hole.The utility model can effectively compensate for pin-and-hole mismachining tolerance and abrasion caused by gap, improve the service life of equipment.
Description
Technical field
A kind of expansion pin is the utility model is related to, specifically, is related to a kind of quarry tipper tapered expansion pin.
Background technology
In engineering machinery field, bearing pin is widely used between each kinematic pair, is ensured between each kinematic pair just
Often motion.Constantly move, constantly rub in surface between bearing pin and the pin-and-hole coordinated with bearing pin so that bearing pin is ground with pin-and-hole
Damage, such pin-and-hole make it that its diameter is increasing due to friction in use, to just needing to pin-and-hole after to a certain degree
Carry out repair welding, machining.And use scene due to limited conditions, secondary mechanical processing after, the cylindricity of pin-and-hole inner surface and
Axiality hardly results in guarantee, so have impact on the service life of assembling and bearing pin.
Utility model content
The technical problem that the utility model solves is to provide a kind of quarry tipper tapered expansion pin, can effectively mend
Repay pin-and-hole mismachining tolerance and abrasion caused by gap, improve the service life of equipment.
Technical scheme is as follows：
A kind of quarry tipper tapered expansion pin, including taper bearing pin, tapered sleeve, pad, bolt, tapered sleeve, pad, bolt according to
Secondary to be arranged on taper bearing pin both sides, tapered sleeve, pad are sleeved on bolt, and taper bearing pin is provided at both ends with screwed hole, bolt peace
In screwed hole.
Further：Taper bearing pin is shaped as cylinder, and both ends are frustum, and the taper surface of frustum is used for the inner cone with tapered sleeve
Shape face coordinates, and screwed hole is opened at the end face center of frustum.
Further：Tapered sleeve is arranged on taper surface, and the taper in the inner conical face of tapered sleeve is identical with the taper of taper surface.
Further：Groove is provided with tapered sleeve.
Further：Four grooves are spaced 90 degree of arrangements on the outer wall of tapered sleeve.
Compared with prior art, the utility model technique effect includes：
The utility model is simple in construction, easy installation and removal, can effectively improve due to pin-and-hole mismachining tolerance and abrasion production
The problem of raw, so as to gap caused by effectively compensating for the mismachining tolerance of pin-and-hole and abrasion, improve the service life of equipment.
Brief description of the drawings
Fig. 1 is the structural representation of quarry tipper tapered expansion pin in the utility model；
Fig. 2 is the profile of taper bearing pin in the utility model；
Fig. 3 is the structural representation of tapered sleeve in the utility model.
Embodiment
Technical solutions of the utility model are elaborated below with reference to example embodiment.However, example embodiment
It can in a variety of forms implement, and be not understood as limited to embodiment set forth herein；Conversely, there is provided these embodiments
So that the utility model is more comprehensively and completely, and the design of example embodiment is comprehensively communicated to those skilled in the art
Member.
As shown in figure 1, it is the structural representation of quarry tipper tapered expansion pin in the utility model.
Quarry tipper tapered expansion pin includes：Taper bearing pin 1, tapered sleeve 2, pad 3, bolt 4, tapered sleeve 2, pad 3, bolt
4 are successively set on the both sides of taper bearing pin 1, and tapered sleeve 2, pad 3 are sleeved on bolt 4, and taper bearing pin 1 is provided at both ends with screwed hole
12, screwed hole 12 is used for assembling bolt 4.
Bolt 4 and pad 3 are used for tapered sleeve 2 and taper bearing pin 1 being assembled together, the external screw thread and cone pin of bolt 4
The internal thread of the screwed hole 12 of axle 1 is consistent.
As shown in Fig. 2 it is the profile of taper bearing pin in the utility model.
The main body of taper bearing pin 1 is cylinder, and both ends be frustum 11, the taper surface 13 of frustum 11 for in tapered sleeve 2
Taper surface 13 coordinates, and screwed hole 12 is opened at the end face center of frustum 11.
As shown in figure 3, it is the structural representation of tapered sleeve 2 in the utility model.
Tapered sleeve 2 is arranged on taper surface 13.The taper in the inner conical face of tapered sleeve 2 is as the taper of taper surface 13, four
Groove 21 is spaced 90 degree of arrangements on the outer wall of tapered sleeve, so that tapered sleeve 2 diametrically has a deflection.
When pin-and-hole due to abrasion or mismachining tolerance, have a diameter larger than defined diameter.Taper bearing pin 1 is arranged on pin first
In hole, then by two tapered sleeves 2 installed in the both ends of taper bearing pin 1, pad 3 and bolt 4 then are arranged on into tapered sleeve 2 two hold
The screwed hole 12 in face.During to the rotation of bolt 4 plus moment of torsion, malleation is produced between the contact surface of tapered sleeve 2 and taper bearing pin 1
Power, due to being machined with 4 grooves 21 on tapered sleeve 2, so taper bearing pin 1 diametrically constantly struts tapered sleeve 2 so that tapered sleeve 2
External cylindrical surface and the inner surface of pin-and-hole reach defined cooperation, produced so as to effectively compensate for the mismachining tolerance of pin-and-hole and abrasion
Gap, improve the service life of equipment.
Term used in the utility model is explanation and exemplary and nonrestrictive term.Due to the utility model energy
It is enough to be embodied in a variety of forms without departing from the spiritual or substantive of utility model, it should therefore be appreciated that above-described embodiment is unlimited
It in any foregoing details, and should widely be explained in the spirit and scope that appended claims are limited, therefore fall into power
Whole changes and remodeling in profit requirement or its equivalent scope all should be appended claims and covered.
