Description
Technical field
The present invention relates to chain transmission part, be specifically related to oil-storable self-lubricating bush chain.
Technical background
Traditional bushing chain is made up of inner chain sheet, outer chain sheet, sleeve and bearing pin.Inner chain sheet and sleeve are drive fit, outer chain sheet and bearing pin also are drive fit, and the sleeve sky is enclosed within on the bearing pin to movingly, because, the wearing and tearing of chain always occur in the surface of contact place of bearing pin and sleeve, so, must stay a little gap between the inside and outside chain sheet, lubricant oil can be penetrated in the gap that bearing pin and sleeve cooperate go, to increase the service life.To the chaindriven lubricated main lubricant oil that adopts, under wet environment, should adopt lubricating grease.Lubricated or the flooding system lubrication regularly of intermittent oiling is adopted in the generally low and unessential chain-driven to speed, and drop lubrication or continuous lubrication are adopted in the chain-driven higher and important to speed.Though intermittent oiling is lubricated simple, lubricated uneven situation appears easily; Though flooding system lubrication regularly is reliable, operates cumbersome; Drop lubrication needs with oil can or drop feed oiler lubricant oil to be dropped on the chain, and is also not easy; Though continuous lubrication is effective, configuration oil sump and oil pump, complex structure.Adopt above lubricating system evenly to have the problem that the Transmitted chains oil storage is not enough and be not easy to keep.In addition, also exist the dirt and the water capacity easily to enter the defective of rotary part.
Summary of the invention
The purpose of this invention is to provide a kind of oil-storable self-lubricating bush chain, it can store lubricating grease, improves lubricating condition, reduces wear, and increases the service life.
Oil-storable self-lubricating bush chain of the present invention, connect and compose by several elementary cells, an elementary cell comprises bearing pin (1), sleeve (2), outer plate (3) and inner plate (4), it is characterized in that: each elementary cell is provided with a tubulose grease storage cavity (5) or is provided with two ring-type grease storage cavities (6) or is provided with a tubulose grease storage cavity and two ring-type grease storage cavities;
Tubulose grease storage cavity is made of the inwall of the conduit (7) that is located at the sleeve outside and the outer wall of sleeve (2);
Ring-type grease storage cavity is made of connecting sleeve (8), the inner plate lower cover (4b) that is held in the inner plate loam cake (4a) on connecting sleeve top and is held in the connecting sleeve bottom;
On sleeve (2), be provided with the oilhole (2a) that communicates with tubulose grease storage cavity (5) or be provided with the oilhole (2b) that communicates with two ring-type grease storage cavities (6) or be provided with the opening (2c) that communicates with tubulose grease storage cavity (5).
Can store lubricant grease in tubulose grease storage cavity and the ring-type grease storage cavity, and keep easily; Store lubricant grease and enter gap between bearing pin and the sleeve, lubricating condition is significantly improved, thereby reduce the wearing and tearing between bearing pin and the sleeve, prolong the working life of chain by oilhole on the sleeve or opening.It is many more that elementary cell is provided with the grease storage cavity, and effect is good more.
Described oil-storable self-lubricating bush chain is provided with seal ring (9) between outer plate and inner plate.The work one of seal ring is to prevent that dirt and water from entering the rotary part of chain, the 2nd, prevent that lubricant grease from leaking outside.
The present invention compares with prior art and has the following advantages: owing to be provided with the grease storage cavity in structure, it can be stored lubricating grease and realize selflubricating; It is permanent that lubricating condition keeps, and dirt and water are not easy to enter rotary part, have reduced the wearing and tearing between sleeve and the bearing pin, prolongs the working life of chain; Reduce the maintenance workload of chain drive.
