Description

Technical Field

[0001] This utility model relates to the field of worm gear technology, specifically a sliding lifting worm gear lubrication mechanism. Background Technology

[0002] Worm gears have advantages such as large transmission ratio, small size, and strong load-bearing capacity, and are therefore widely used in the field of industrial machinery.

[0003] Application number CN202121144030.1 discloses an adaptive lubrication worm gear head. The lubricating oil is poured into the machine body through the oil injection hole. The lubricating oil will compress the sliding ball, causing the sliding ball to move downward, which will drive the spring to move downward. The lubricating oil can enter the machine body after passing through the filter screen. The valve handle is equipped with an anti-slip pad to prevent slippage when turning the valve handle. Two first screws are used to limit the rotation position of the worm gear and keep it within a range. When adding lubricating oil, the second screw needs to be turned to discharge the gas in the machine body through the second threaded cylinder.

[0004] The lubrication structure described in the above application involves adding paste-like lubricating oil through an oil injection hole to maintain the lubrication of the worm gear. However, it is not convenient to replace the lubricating oil, and the worm gear will become stuck due to lubricating oil failure after long-term use. Therefore, a simple and easy mechanism for replacing the lubricating oil of the worm gear is needed. Utility Model Content

[0005] Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a sliding lifting worm gear lubrication mechanism, which solves the problems mentioned in the background technology.

[0006] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A sliding lifting worm gear lubrication mechanism includes a drawer-type frame 1, a slider 5, and a liftable oil box 10. The drawer-type frame 1 has a fixed inclined slide rail 8 and a rear vertical surface 9 at its rear. The slider 5 is installed inside the drawer-type frame 1. The slider 5 has a slider inclined slide rail 6 and a slider vertical surface 7 on the side near the fixed inclined slide rail 8. The liftable oil box 10 is installed inside the drawer-type frame 1 and can hold lubricating oil. The bottom of the liftable oil box 10 contacts the fixed inclined slide rail 8 and the slider inclined slide rail 6. The slider inclined slide rail 6 moves away from the fixed inclined slide rail 8 as the slider 5 moves. When the liftable oil box 10 slides down along the fixed inclined slide 8 and the slider inclined slide 6 to disengage from the lubricated worm gear, and the slider inclined slide 6 moves closer to the fixed inclined slide 8 along with the slider 5, the liftable oil box 10 slides up along the fixed inclined slide 8 and the slider inclined slide 6 to make the lubricating oil contained in the liftable oil box 10 contact the lubricated worm gear, and the liftable oil box 10 reaches its highest point when its side contacts the rear facade 9 of the frame and the facade 7 of the slider respectively. The maximum height that the liftable oil box 10 can rise can be adjusted by changing the processing height of the fixed inclined slide 8 and the slider inclined slide 6.

[0007] Preferably, a connecting rod 3 is installed on the slider 5, and a knob 2 is installed on the other end of the connecting rod 3. Pulling the knob 2 can move the slider 5 away from the fixed inclined slide 8 through the connecting rod 3.

[0008] Preferably, a spring 4 is installed between the slider 5 and the drawer-type frame 1, and the spring 4 can push the slider 5 closer to the fixed inclined slide rail 8.

[0009] Preferably, after the liftable oil box 10 is lowered, the drawer-type frame 1 can be pulled out to check or replace the lubricating oil contained in the liftable oil box 10.

[0010] Preferably, after the liftable oil box 10 is raised, the lubricated worm gear enters the liftable oil box 10 to prevent it from moving horizontally, and at the same time locks the drawer-type frame 1 so as to stably maintain the lubrication of the worm gear.

[0011] Beneficial effects: Compared with the prior art, the advantages of this utility model are as follows: Compared with the worm gear lubrication methods in the prior art or others, this utility model allows for convenient lowering of the liftable oil box by pulling the knob to drive the slider. After the lowered liftable oil box disengages from the lubricated worm gear, the drawer-type frame can be pulled out to check the quality and quantity of the lubricating oil, and to replace or add lubricating oil as needed. After checking or replacing the lubricating oil, the drawer-type frame can be pushed in, the knob released, and the slider automatically slides to one side of the fixed inclined slide of the drawer-type frame under the push of the spring. The combined action of the fixed inclined slide rail converts the horizontal movement of the slider into the vertical movement of the liftable oil box. The liftable oil box automatically rises, allowing the worm gear to enter the oil box. The lubricating oil contained in the liftable oil box wets the worm gear, thus completing the lubrication work of the worm gear. While the liftable oil box wets the worm gear, the change in the relative position between the worm gear and the liftable oil box restricts the horizontal movement of the liftable oil box, thereby preventing the drawer-type frame from being pulled out. This achieves a locking function, preventing accidental removal of the drawer-type frame and the worm gear from operating without lubrication. Attached Figure Description
