Technical Field

The invention relates to the field of wind generating sets and engineering machinery, in particular to a lubricating grease distribution and conveying mode of a sliding slewing bearing.

Background

Maintaining good lubrication conditions is important for sliding slewing bearings, and in addition to forming an oil film on the friction surfaces to reduce sliding member wear, a stable coefficient of friction can be maintained on the friction surfaces.

At present, sliding slewing bearing lubrication design mainly comprises two schemes, namely, referring to a rolling slewing bearing scheme, arranging a greasing pipeline, and setting a greasing program to automatically convey lubricating grease to each lubrication point; and secondly, regularly and manually smearing lubricating grease on the lubricating points. The first scheme can ensure that the sliding part is fully lubricated, but the grease adding points are many, and the structural design is complex; scheme two realizes simply, but can have the not enough risk of lubrication.

Disclosure of Invention

Aiming at the characteristics of the sliding slewing bearing and the defects and shortcomings of the conventional lubricating grease adding scheme of the sliding slewing bearing, the invention provides a lubricating grease distribution conveying mode of the sliding slewing bearing, and lubricating grease is conveyed to each lubricating point through a reasonable grease adding strategy and structural design. The scheme of the invention is as follows.

The invention comprises at least the following components: the device comprises a greasing device, a supporting piece, a supported piece, an upper friction plate, a radial friction plate, a lower friction plate, a clamping block and a grease guide plate.

The upper surface of the upper friction plate is embedded in a groove on the bottom surface of the supported part, and the lower surface of the upper friction plate is in contact with the upper surface of the supported part. The radial friction plate is positioned between the inner side of the supporting piece and the outer side of the clamping block. The lower friction plate is supported by a disc spring in the clamping block. The upper surface of the lower friction plate is in contact with the lower surface of the support member. The grease guide plate is arranged on the surface of the clamping block where the lower friction plate is located.

At least one side of the side surface of the upper friction plate, which is perpendicular to the movement direction of the slewing bearing, is of an inclined surface structure, and the inclined surface structure can penetrate through the thickness of the friction plate or can not penetrate through the thickness of the friction plate to form an open inclined groove structure.

At least one side of the radial friction plate perpendicular to the moving direction of the slewing bearing is of an inclined plane structure, and the inclined plane structure can penetrate through the thickness of the friction plate or can not penetrate through the thickness of the friction plate to form an open inclined groove structure.

When the sliding slewing bearing performs slewing action, after the greasing device delivers lubricating grease to the upper surface of the supporting part, the upper friction plate and the supporting part move relatively, and the lubricating grease supplies lubricating oil to the upper friction plate and flows to the inner side surface of the supporting part, namely the position of the radial friction plate under the action of the inclined surface structure on the side surface of the upper friction plate. The radial friction plate and the supporting piece move relatively, lubricating grease can provide lubrication for the radial friction plate, meanwhile, the lubricating grease flows to the surface of the clamping block where the lower friction plate is located under the action of the inclined surface structure on the side surface of the radial friction plate, and the lubricating grease is accumulated around the lower friction plate under the action of the grease guide plate to provide lubrication for the lower friction plate.

The invention has the beneficial effects that: according to the characteristics of the sliding slewing bearing, the lubricating grease is conveyed to the lubricating points of the upper friction plate, the radial friction plate and the lower friction plate by utilizing the flowing rule of the lubricating grease under the action of the inclined surface structure. The invention utilizes the characteristic of the sliding slewing bearing and realizes the function of distributing and conveying lubricating grease by reasonable greasing strategy and structural design.

The grease guide plate 8 is arranged on the surface of the clamping block 7 where the lower friction plate 6 is arranged.

As shown in the drawing, the side surface of the upper friction plate 4 perpendicular to the moving direction of the slewing bearing is of a slope structure, and the slope structure does not penetrate through the thickness of the friction plate to form an open chute structure, and the open chute structure is arranged on the surface contacting with the supporting member 2.

The radial friction plate 5 and the supporting member 2 move relatively, and grease lubricant provides lubrication for the radial friction plate 5, flows down to the surface of a clamping block 7 where the lower friction plate 6 is located under the action of a slope structure on the side surface of the radial friction plate 5, and is accumulated around the lower friction plate 6 under the action of a grease guide plate 8 to provide lubrication for the lower friction plate 6.
