Embodiment 1

[0016] Such as figure 1 As shown, the core seal of the design method of the composite solid lubrication sprocket shaft group includes a floating seal ring 1 and a sealing flange 4, and the floating seal ring 1 is composed of two geometrically identical metal rings. One is a floating ring 3, which is fixed on the sealing flange 4; the other is a stationary ring 2, and the stationary ring 2 and the floating ring 3 are fitted together for relative movement to achieve a sealing effect.

[0017] Such as figure 2 As shown, the annular latent pit 5 structure is adopted on the fitting surface of the stationary ring 2, the fitting surface of the floating ring 3 is smooth, the size of the latent pit 5 is Φ2.5mm*1mm, and the distance between adjacent latent pits 5 is 5mm. Solid lubricant is arranged in latent pit 5.

[0018] When working, the stationary ring 2 and the floating ring 3 move relatively, and the annular latent pit 5 structure is used on the bonding surface of the stationa...

Embodiment 2

[0020] The structure of this embodiment is basically the same as that of Embodiment 1, except that the bonding surface of the floating ring 3 adopts the structure of an annular latent pit 5, and there is a solid lubricant in the latent pit 5, while the bonding surface of the stationary ring 2 is a smooth surface.

[0021] The joint surface of any one of the two metal rings of the floating sealing ring 1 adopts the structure of the annular latent pit 5, which can achieve the expected effect in practical applications.

Embodiment 3

[0023] Such as image 3 As shown, the bearing 6 is a commonly used bearing, which is composed of an inner ring 7, an outer ring 8, a cage 9 and a rolling element 10, and a latent pit is used on the contact surface of the cage 9, the inner ring 7 and the outer ring 8 5 structure, there is solid lubricant in latent pit 5. The size of the latent pits 5 is Φ2.5mm*1mm, and the distance between adjacent latent pits 5 is 5mm.

[0024] During operation, the latent pit 5 structure is used on the retainer 9 of the bearing 6 to ensure sufficient composite solid lubricant compensation on the surface of the rolling elements, so that the solid lubricant transferred on the moving track of the inner and outer rings of the bearing forms a firm and reliable composite lubricant. Solid lubricating film, which improves the load capacity of the sprocket shaft group bearings, reduces wear and improves the life of the bearings.

Abstract

The invention belongs to the field of work machinery and relates to a design method for a sprocket shaft group, in particular to a design method for a composite solid lubrication sprocket shaft group. The designed sprocket shaft group at least comprises a floating seal ring and a seal flange, wherein the floating seal ring comprises two geometrically identical metal rings, the floating ring is fixedly connected with the seal flange, and the static ring adheres to the floating ring and moves relatively to the floating ring. The design method is characterized in that the adhering surface of the floating ring or static ring is in an annular submerged pit structure, and solid lubricant is filled in the submerged pit. The designed sprocket shaft group further comprises a bearing composed of an inner ring, an outer ring, a retainer and a rolling body, and is characterized in that the contact surface between the retainer and the inner surface and the contact surface between the retainer and the outer ring are in the submerged pit structures, and the solid lubricant is filled in the submerged pit. Due to the design method for the composite solid lubrication sprocket shaft group, the phenomena such as oil leakage, unreliability of lubrication, too fast abrasion of the floating seal ring, excessive abrasion of a bearing inner sleeve, damages on a bearing retainer, excessive abrasion of a spline, damages on a gear coupler, etc. existing in the sprocket shaft group are avoided.

Description

technical field [0001] The invention belongs to the field of operating machinery, and relates to a design method of a sprocket shaft group, in particular to a design method of a composite solid lubricated sprocket shaft group. Background technique [0002] The sprocket shaft group of the bendable scraper conveyor and the scraper loader of the shearer is the key component of the fully mechanized mining equipment in the coal mine. The technical improvement related to it is directly related to the efficiency and benefit of the coal mine fully mechanized mining system. Since the first chain shearer was born in the UK in the 1940s, the oil leakage of the scraper sprocket shaft group has caused damage to this component, which has always been the crux of the technical progress of the coal shearer, especially with the With the rapid development of economy and society, the social production capacity of energy is constantly being promoted by demand, and the non-stop continuous operat...
