Description

Technical Field

[0001] The utility model relates to the technical field of lithium electric drills, in particular to a lubrication structure for a gear box of a lithium electric drill. Background Art

[0002] Lithium-ion drills are tools used to turn screws to force them into place. They are drilling tools that use electricity as power. They are common products among power tools and are also the most in-demand power tool products. The gearbox is an important mechanical component in lithium-ion drills. Its main function is to transmit the power generated by the motor output end to the fixture, driving the fixture drill bit to rotate accordingly.

[0003] The existing lithium-ion drill gearboxes are all wrapped inside the lithium-ion drill, and the staff needs to disassemble the device casing and apply lubricant for maintenance. The operation is cumbersome, and the gears are likely to fall off during the disassembly process, increasing the difficulty of maintenance. Therefore, we propose a lubrication structure for lithium-ion drill gearboxes. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art. The existing lithium electric drill gear box requires workers to disassemble the device casing and then apply lubricant for maintenance, which is cumbersome to operate and easily causes gears to fall off during the disassembly process, increasing the difficulty of maintenance.

[0008] The lubrication assembly includes a connecting rod, and a driving gear is provided at one end of the connecting rod extending to the interior of the box body. An external gear is sleeved on the periphery of the driving gear and located inside the box body. A plurality of fixing rods are arranged around the front of the external gear, and a circular sleeve is arranged at one end of the fixing rod away from the external gear. Slide bars are arranged at both ends of the circular sleeve corresponding to the circular slide grooves. A plurality of leakage holes are opened at equal intervals around the periphery of the circular sleeve and located between two of the slide bars, and a wear-resistant sponge is arranged inside the circular sleeve and around the periphery of the gear set.

[0009] As a preferred solution of the utility model, the injection port is connected with the box body and the leakage hole.

[0010] The technical effect of adopting the above further solution is that the lubricant is injected into the box through the injection port and flows into the wear-resistant sponge through the leakage hole, which facilitates the lubrication operation of the gear set.

[0011] As a preferred solution of the utility model, the connecting rod is matched with the second circular groove, and the driving gear is fixedly connected to the connecting rod.

[0012] The technical effect of adopting the above further solution is: the driving gear can be driven to rotate by rotating the connecting rod, thereby improving the convenience of operation.

[0013] As a preferred solution of the utility model, the external gear is meshed and connected with the driving gear, the external gear is adapted to the housing, and the two ends of the fixing rod are fixedly connected to the external gear and the annular sleeve respectively.

[0014] The technical effect of adopting the above further solution is: the outer gear can be driven to rotate by the driving gear, so that it drives the annular sleeve to rotate through the fixing rod, thereby performing a lubrication operation on the gear set.

[0015] As a preferred solution of the utility model, the annular sleeve is matched with the box body, the sliding bar annular sleeve is fixedly connected, and the sliding bar is slidably connected with the circular sliding groove.

[0016] The technical effect of adopting the above further solution is: through the sliding connection between the slide bar and the circular slide groove, the annular sleeve can rotate more smoothly, thereby improving its working efficiency.

[0017] As a preferred solution of the utility model, the wear-resistant sponge is matched with the annular sleeve.

[0018] The technical effect of adopting the above further solution is that the lubricant can be absorbed by the wear-resistant sponge, so that it is distributed more evenly, and the lubrication operation of the gear set is more uniform.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, through the design of the box body and the lubrication assembly, the use of the connecting rod in conjunction with the external gear can perform lubrication and maintenance on the gear set without opening the device casing, thereby preventing accidental loss of the gears and effectively improving the convenience of operation. The use of the circular sleeve greatly reduces the difficulty of maintaining the gear set. BRIEF DESCRIPTION OF THE DRAWINGS
