Preferably, the butt joint piece includes that a plurality of fixes butt joint post in the deformation inslot, it is a plurality of angular distribution such as butt joint post, and with to interface looks adaptation, the equidistance is opened in the deformation inslot has a plurality ofly and another the butt joint groove of butt joint post looks adaptation on the contact pad, realizes spacing the installation to the contact pad through the butt joint piece.

Preferably, all open the recess that is used for receiving the outside deformation of extrusion in butt joint post outer end for can more stable butt joint after receiving the extrusion.

Preferably, a plurality of heat discharging holes are formed in the gasket core at equal angles, and the heat discharging holes are communicated with the butt joint port to play a role in heat dissipation.

Preferably, a corrugated ring is installed in the contact pad, and a heat dissipation groove is formed on the outer side of the contact pad, so that the contact pad can extend when being pressed by the corrugated ring.

Preferably, the contact pad is made of asbestos-free fiber rubber, and the pad core is made of metal copper, so as to improve strength.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model is manufactured by optimizing the existing gasket, and mutually butting the high-strength gasket core and the two contact gaskets, can be stably butted by matching with a butting piece, and can be reused by replacing the contact gaskets when being worn, thereby prolonging the service life.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1-3, a high-strength thrust washer shown in the drawings includes a washer core 1 and contact washers 2 mounted on two sides of the washer core 1, the washer core 1 has a cross-sectional shape of a T-shaped structure, a butt-joint member 3 is mounted on a contact surface of the contact washer 2 and the washer core 1, the washer core 1 is provided with a plurality of butt-joint ports 4 adapted to the butt-joint member 3, and a deformation groove 5 is formed in a position of the contact washer 2 corresponding to the butt-joint member 3.

It should be noted that: in the scheme, the cross sections of the two contact gaskets 2 are L-shaped, and the two contact gaskets are buckled and covered on two sides of the gasket core 1.

Referring to fig. 5, the docking member 3 shown in the figure includes a plurality of docking posts 6 fixed in the deformation groove 5, the docking posts 6 are distributed at equal angles and fit with the docking ports 4, and a plurality of docking grooves 7 are equidistantly formed in the deformation groove 5 and fit with the docking posts 6 on another contact pad 2.

It should be noted that: the number of the butt joint openings 4 is twice that of the butt joint posts 6, and the butt joint posts 6 on the inner sides of the two contact gaskets 2 are mutually spliced in the butt joint openings 4 and clamped with the butt joint grooves 7, so that the butt joint of the two contact gaskets 2 is more stable.

It is worth noting that: all open 6 outer ends of docking post and be used for receiving the recess 8 of the outside deformation of extrusion, the existence of recess 8 for docking post 6 can extrude downwards when receiving the extrusion, makes 6 bottom of docking post outwards expand, thereby more stable with 7 joints in butt joint groove, and the deformation groove 5 of simultaneous design also satisfies contact pad 2 and outwards deforms when receiving the extrusion, makes and offsets in the 1 outside of gasket core, makes the butt joint more stable.

Principle of improving thrust washer intensity: at first personnel are through the gasket core 1 that adopts the metal material for the intensity of gasket core 1 is very high, and later two contact pads 2 of rethread butt joint, make all functions that can satisfy current thrust gasket, use a period after, and contact pad 2 damages to some extent, through dismantling contact pad 2 this moment, the contact pad 2 of renewal, thereby can reuse, when improving intensity, also increase the number of times of use, reduce the cost.

Example 2

Referring to fig. 3 and 4, in this embodiment, for further explanation of example 1, a plurality of heat discharging holes 9 are formed in the gasket core 1 at equal angles, and the plurality of heat discharging holes 9 are communicated with the interface 4;

meanwhile, a wave-shaped ring 10 is arranged in the contact pad 2, and a heat dissipation groove 11 is arranged on the outer side of the contact pad 2

It is worth noting that: contact pad 2 adopts no asbestos fibre rubber material to make, and gasket core 1 adopts the metallic copper material to make, under the condition that plays the gasket function, very big saving the cost.

In this embodiment, heat extraction hole 9 through the design is linked together with interface 4, cooperates the radiating groove 11 that begins in the contact pad 2 outside to can discharge the heat that the friction produced on the contact pad 2 effectively, avoid the damage that high temperature brought, the wave form ring 10 that adds simultaneously in inside makes contact pad 2 can have certain extensibility.
