[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1-3As shown, a tensioner assembly with an oil injection hole proposed in an embodiment of the utility model comprises a tensioner body 1, a pulley 2, a filling port 3, a control member 4 and a bolt 5. The tensioner assembly with an oil injection hole designed in this scheme can achieve the effect of lubricating the pulley 2 with oil, improve the transmission effect, and can extend the lubrication time, and reduce the frequency of subsequent lubrication and maintenance. The tensioner body 1 is rotatably connected with the pulley 2, the filling port 3 is symmetrically arranged on the pulley 2, and the control member 4 is symmetrically arranged in the cavity of the pulley 2. The pulley 2 is matched with the bolt 5, and the bolt 5 is matched with the tensioner body 1 in threaded connection. The pulley 2 is sleeved on the outer ring of the bearing 102 through the rotating hole 201, the bolt 5 is inserted into the rotating hole 201 and is threadedly connected with the mounting seat 101, and the abutment plate 501 is arranged to rotate and abut with the pulley 2, so that the pulley 2 is installed on the tensioner body 1, and the pulley 2 is used for tensioning the belt drive. When the belt drives the pulley 2 to rotate, because the pulley 2 has just started to rotate, the centrifugal force is small. At this time, under the action of the centrifugal force, the lubricating oil in the oil storage tank 203 will enter the sliding frame 401 from the oil inlet 402, and then be discharged to the oil outlet 202 through the connecting hole 403, and be coated The sliding block 404 is covered on the surface of the pulley 2 and is used for lubricating the belt. At this time, the centrifugal force is smaller than the rebound force of the spring 405, and the sliding block 404 will remain motionless in the sliding frame 401. When the pulley 2 rotates at a constant speed, the centrifugal force can swing the sliding block 404, so that the sliding block 404 is blocked at one end of the connecting hole 403, and the spring 405 will be stretched and maintain the rebound force. At this time, the connecting hole 403 and the oil inlet 402 are blocked by the sliding block 404, so that the lubricating oil inside the oil storage tank 203 can be prevented from being thrown out, thereby increasing the service life of the lubricating oil stored inside. When the pulley 2 stops rotating, , the spring 405 can rebound and reset, so that the sliding blocking block 404 is reset. At this time, the oil inlet 402 and the connecting hole 403 are exposed, and when the pulley 2 starts to rotate next time, under the action of centrifugal force, the lubricating oil inside the oil storage tank 203 can be thrown off and sprayed onto the belt, thereby meeting the lubrication effect of the belt. When the lubricating oil inside the oil storage tank 203 is used up, the threaded sealing plug 301 can be opened to add lubricating oil to the oil storage tank 203 through the filling port 3 to meet the replenishment of the lubricating oil.
