Detailed Description
As shown in fig. 1 to 3, an internal oiling structure of a lubrication chain pin bush comprises a lubrication sleeve 2, two sides of the lubrication sleeve 2 are respectively matched with an inner chain plate 1, an outer chain plate structure 3 is arranged on the outer side of the inner chain plate 1, a pin shaft 4 is sleeved in the lubrication sleeve 2, the pin shaft 4 connects the outer chain plate structure 3 with the inner chain plate 1, and the two structures are combined together. And an oil filling hole 5 is formed in one side of the connecting position of the outer chain plate structure 3 and the pin shaft 4, and lubricating liquid is filled from the outer side position to the inside by using an oil gun from the structure in later use. The outer end face of the lubrication sleeve 2 is provided with a conical guide surface 7 inclined to the central axis direction, and the inner position forms a transitional lubrication fit effect between the movable surfaces, so that the lubrication liquid can stay at the position, and a larger amount of lubrication liquid at the inner position is ensured. The contained angle of toper guide surface 7 and horizontal direction is 15 degrees, can not influence the structural strength of sleeve position, also can play reliable lubrication direction cooperation simultaneously. The position of the pin shaft 4 and the lower end position of the conical guide surface 7 on the same plane is provided with a lubrication fit safety groove 6, so that the movable surface position of the pin shaft position is positioned in the middle position of the inner lubrication fit groove, and the lubrication efficiency of lubricating the main body movable surface position by the lubrication liquid is higher and the lubrication is more comprehensive. The novel structure design is adopted, and the mutually matched oiling structures are arranged on the outer chain plate, the inner sleeve structure and the pin shaft, so that lubricating liquid can be uniformly and smoothly conveyed to the movable interval inside the pin shaft during use, the smoothness during lubrication is guaranteed, the safety of the chain during use is effectively improved, the whole chain has longer service life and better durability during use, the structure is relatively simple, and the cost during production and use is relatively low.
Preferably, the oil filling hole 5 has a semi-cylindrical structure, which is more convenient in production and processing, and the efficiency in production can be further improved.
Preferably, the oil filling hole 5 has a tapered structure, and the size of the outer side of the oil filling hole 5 is larger than the size of the side position close to the inner link plate 1, so that the lubrication smoothness of the filling position is better and the efficiency of conveying the lubrication to the inside is higher when the lubrication liquid is filled.
Preferably, the projection of the oil filling hole 5 in the up-down direction is located in the area of the projection of the lubrication fit safety groove 6 in the up-down direction, so that the area of the internal position is larger when lubrication is performed, and the fit smoothness when the lubrication liquid is fitted to the movable surface position can be effectively improved.
While the foregoing is directed to the preferred embodiments of the present utility model, it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions should also be considered to be within the scope of the present utility model.
