DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 2 and Figure 4 As shown, in this embodiment, a loader yoke with a lubrication device includes a yoke head 1, characterized in that: a shaft sleeve 2 is slidably inserted at both ends of the yoke head 1, a needle bearing 3 is slidably inserted inside the two shaft sleeves 2, and the same connecting shaft 4 is slidably inserted relative to the two needle bearings 3, and a lubrication component 6 is installed in the connecting shaft 4, and the lubrication component 6 includes an oil tank 601 fixedly installed in the middle of the top outer wall of the connecting shaft 4, a main oil outlet groove 603 is opened in the middle of the top outer wall of the connecting shaft 4, the main oil outlet groove 603 is connected with the inside of the oil tank 601, and an expenditure oil groove 604 is opened at the top of the circumferential outer wall of the four support rods of the connecting shaft 4, and the four expenditure oil grooves 604 are all connected with the main oil outlet groove 603.

[0021] A one-way valve 602 is threadedly connected to the outer wall of the top of the oil tank 601 , and the one-way valve 602 passes through the top of the oil tank 601 and extends toward the inside.

[0022] First, unscrew the one-way valve 602, and then insert one end of the syringe into the oil tank 601. When the lubricating oil fills the oil tank 601, finally screw the one-way valve 602 into the oil tank 601 to ensure that the lubricating oil can be discharged downward normally, but will not pass through the one-way valve 602 and flow to the outside. The lubricating oil will first enter the main oil outlet groove 603, and then disperse into multiple expenditure oil grooves 604, and finally enter the connection between the connecting shaft 4 and the sleeve 2 from one end of the expenditure oil groove 604, and disperse to the outside of each needle roller along the rotating shaft of the needle roller bearing 3, thereby achieving the purpose of real-time replenishment of lubricating oil.

[0023] like Figure 2 and Figure 3 As shown, the outer walls of the multiple sleeves 2 that are away from each other are all installed with anti-slip components 7, and the anti-slip components 7 include a telescopic rod 701 rotatably connected to the outer wall of one side of the sleeve 2, and a bolt 702 is threadedly connected to the movable end of the telescopic rod 701.

[0024] A screw hole 703 is provided on the outer wall of one side of the yoke head 1 , and the bolt 702 can form a transmission fit with the screw hole 703 .

[0025] Pull the movable end of the telescopic rod 701 outward, and then rotate the telescopic rod 701 so that the bolt 702 at one end is aligned with the screw hole 703 outside the yoke head 1, and then rotate the bolt 702 to make it enter the screw hole 703. At this time, the position of the sleeve 2 can be restricted by the telescopic rod 701, which can further increase the stability of the connecting shaft 4 and avoid the problem of detachment in the connection state of the device.

[0026] like Figure 1 As shown, the outer circumferential walls of the four support rods of the connecting shaft 4 are each provided with a limiting ring 5, the diameter of the limiting ring 5 being larger than the inner diameter of the sleeve 2, and being able to limit the sliding position of the sleeve 2, thereby preventing the sleeve 2 from sliding excessively.

[0027] The utility model provides a loader yoke with a lubrication device, and the specific working principle is as follows:

[0028] When the device is working, first place the connecting shaft 4 between the yoke heads 1, then insert the sleeve 2 into the mounting hole of the yoke head 1, and then make the sleeve 2 sleeve the outside of the needle bearing 3 at one end of the connecting shaft 4, and stop when the sleeve 2 contacts the limit ring 5, and then repeat the operation to install another sleeve 2, then pull the movable end of the telescopic rod 701 outward, and then rotate the telescopic rod 701 so that the bolt 702 at one end is aligned with the screw hole 703 outside the yoke head 1, and then rotate the bolt 702 to make it enter the screw hole 703, at this time, the position of the sleeve 2 can be limited by the telescopic rod 701, and the connection shaft 4 can be further increased. Stability, avoiding the problem of detachment in the connection state of the device, first unscrew the one-way valve 602, and then insert one end of the syringe into the oil tank 601. When the lubricating oil fills the oil tank 601, finally screw the one-way valve 602 into the oil tank 601, so as to ensure that the lubricating oil can be discharged downward normally, but will not pass through the one-way valve 602 and flow to the outside. The lubricating oil will first enter the main oil outlet groove 603, and then disperse into multiple expenditure oil grooves 604, and finally enter the connection between the connecting shaft 4 and the sleeve 2 from one end of the expenditure oil groove 604, and disperse to the outside of each needle roller along the rotating shaft of the needle roller bearing 3, thereby achieving the purpose of real-time replenishment of lubricating oil.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
