Description

One kind is novel to inlay sliding bearing

Technical field

It is specifically a kind of novel to inlay sliding bearing the utility model relates to bearing application technology field.

Background technique

Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced Coefficient of friction in its motion process, and guarantee the part of its rotating accuracy, sliding bearing as the major class in bearing class, it It is the bearing to work under sliding friction.Sliding bearing has the characteristics that stable working, reliable, muting.However, current market On most of sliding bearing mainly rely on film lubrication, this class bearing high temperature, it is high carry, it is corrosion-resistant or can not refuel Occasion using when have some limitations.

Utility model content

Place, the utility model are intended to provide a kind of sliding bearing, make its breakthrough in view of the deficiency of the prior art The limitation of film lubrication, and be suitable for high temperature, it is high carry, the corrosion-resistant or occasions such as can not refuel, thus solve in the prior art according to The deficiency existing for the film lubrication.

In order to solve the above technical problems, one kind provided by the utility model is novel to inlay sliding bearing, including bearing body, The bearing body is equipped with several lubricant putting holes for penetrating the bearing body inner and outer wall, and the lubricant is placed Hole is round boss structure, and the circular open A that the lubricant putting hole is located at the bearing body inner wall is greater than positioned at described The circular open B of bearing body outer wall, the boundary line of two circular open of lubricant putting hole and the two circular open centers of circle Line form angle, the angle is that solid lubricant is equipped with inside the lubricant putting hole between 10~45 °.

The bearing body is made using CuZn24A16 of basis material.

The bearing body both ends of the surface are excessive by rounded corner with the inside and outside wall of bearing body.

The circular open A and circular open B are coaxial, and the center of circle circular open A is parallel with the line in the center of circle circular open B In the upper surface of bearing body.

The solid lubricant is Hmp grease.

Utility model has the advantages that the utility model on bearing body by being arranged lubricant putting hole and placing Solid lubricant, to guarantee lubrication of the bearing body in equipment operation；Also, bearing body is using CuZn24A16 as matrix Material is made, and having bearing body, self-lubricating capacities are strong, wear-resisting property is good, keep oil film clearly characteristic, can be preferably right Bearing body surface protection enables the novel sliding bearing of inlaying of the utility model to be more applicable for high temperature, height without frayed It carries, the corrosion-resistant or occasions such as can not refuel；Also, solid lubricant is Hmp grease, and high temperature resistant anti-pressure ability is strong, has Splendid chemical inertness, durability and low volatility, further forms protection to bearing main body.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of the utility model vertical profile.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

As Figure 1-Figure 2, one kind provided by the utility model of the utility model is novel inlays sliding bearing, including axis Ontology 1 is held, the bearing body 1 is equipped with several lubricant putting holes 2 for penetrating 1 inner and outer wall of bearing body；Institute The effect for stating lubricant putting hole 2 is mainly convenient to the placement of solid lubricant 6, is convenient to bearing body 1 when equipment operation Lubrication.

The lubricant putting hole 2 is round boss structure, and the lubricant putting hole 2 is located in the bearing body 1 The circular open A3 of wall is greater than the circular open B4 positioned at 1 outer wall of bearing body, and 2 liang of circles of the lubricant putting hole are opened The boundary line of mouth and the line in the two circular open centers of circle form angle 5, and the angle 5 is between 10~45 °；By the lubrication The circular open A3 setting that agent putting hole 2 is located at 1 inner wall of bearing body is greater than the circle positioned at 1 outer wall of bearing body Be open B4, primarily to being convenient to the placement of solid lubricant 6, and locks solid lubricant 6, reduces outside solid lubricant 6 Angle 5 is set as between 10~45 °, mainly guarantee solid lubricant 6 can be locked in lubricant as far as possible by excessive possibility Without wasting in putting hole 2, guarantee solid lubricant 6 to the lubrication of running equipment；Meanwhile angle 5 is 10~45 ° and will not influence The ability to bear to power of bearing main body 1.Solid lubricant 6 is equipped with inside the lubricant putting hole 2.

The bearing body 1 is made using CuZn24A16 of basis material.CuZn24A16 is high-tensile strength brass, is copper alloy material There is a kind of very high-intensitive and hardness multielement wear-resistant material in material, have self-lubricating capacities strong, wear-resisting under fuel cut-off condition Therefore the advantages that performance is good, holding oil film is clear is the basis material of bearing body 1 using CuZn24A16, can be preferably right 1 surface protection of bearing body enables the novel sliding bearing of inlaying of the utility model to be more applicable for high temperature, height without frayed It carries, the corrosion-resistant or occasions such as can not refuel.

1 both ends of the surface of bearing body and the inside and outside wall of bearing body 1 are excessive by rounded corner 7；Mainly eliminate sharp rib Angle avoids injury caused by running to workers carry or equipment.

The circular open A3 and circular open B4 are coaxial, and the line in the center of circle circular open A3 and the center of circle circular open B4 It is parallel to the upper surface of bearing body 1, the mainly central axis of guarantee lubricant putting hole 2 and the both ends of the surface of bearing body 1 is flat Row, and perpendicular to the central axis of bearing body 1.

The solid lubricant 6 is Hmp grease；Hmp grease contains the polytetrafluoroethylene (PTFE) lubricated granules of high concentration, High temperature resistant anti-pressure ability is strong, is suitble to high temperature heavy load equipment, and fluorine element Hmp grease is exclusively used in high temperature, high load, chemical attack ring The component that bearing and requirement in border lubricate all the life, has splendid chemical inertness, durability and low volatility.Applicable temperature Range: -50~+280 DEG C, therefore, using Hmp grease, also there is splendid chemical inertness, durability and low volatility, drop The corrosivity of low bearing further forms protection to bearing main body 1.
