Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "up", "down", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, a gear lubrication mechanism includes a gear case 1, and a driving gear 2 and a driven gear 3 engaged with each other are provided in the gear case 1. The top of gear box 1 is equipped with batch oil tank 4, and the top of batch oil tank 4 is equipped with venthole 5, and oil-out 6 has been seted up to the bottom of batch oil tank 4. An oil baffle plate 8 is arranged above the oil outlet 6 in a sliding mode through a sliding groove 7, and the left end of the oil baffle plate 8 penetrates out of the oil storage tank 4 and is fixedly connected with a piston rod of a telescopic cylinder 9.

An oil feeding hose 10 is connected below the oil outlet 6, and a flow rate adjusting device is mounted on the oil feeding hose 10, and comprises a housing 11 and an adjusting roller 12 as shown in fig. 2 and 3. The shell 11 is sleeved on the oil supply hose 10, and two opposite moving chutes 13 are formed in the shell 11; the two moving chutes 13 are arranged on the right side of the oil feeding hose 10 in pairs, and the distance between the moving chutes 13 and the oil feeding hose 10 is gradually reduced from top to bottom. The outer edge of the adjusting roller 12 is abutted against the oil supply hose 10, and the axle 14 is arranged at the axle center of the adjusting roller 12; both ends of the wheel shaft 14 are slidably connected with the housing 11 through the corresponding moving chutes 13. The oil supply hose 10 can be extruded and deformed to different degrees only by moving the adjusting roller 12 up and down along the moving chute 13, so that the flow of lubricating oil is adjusted, and gears below the oil supply hose are fully lubricated. A lock nut 15 is connected to the axle 14 through threads, and after the flow of the lubricating oil is adjusted, the lock nut 15 can be screwed to lock and position the adjusting roller 12.

A locking device is arranged above the driving gear 2 and comprises an extrusion rod 16, a guide seat 17 and a moving plate 18. The extrusion rod 16 is arranged above the driving gear 2 in a sliding mode through the guide seat 17, an extrusion block 19 matched with a wheel groove of the driving gear 2 is arranged at the lower end of the extrusion rod 16, and the upper end of the extrusion rod 16 penetrates through the buffer spring 20 and is fixedly connected with the moving plate 18. The moving plate 18 is provided with a guide chute 21, a guide pin 22 is arranged in the guide chute 21 in a sliding manner, and the guide pin 22 is fixedly connected with a piston rod of the telescopic cylinder 9.

Before the driving gear 2 is driven, the oil baffle plate 8 can slide leftwards only by contracting the piston rod of the telescopic cylinder 9 and move away from the upper part of the oil outlet 6, so that lubricating oil in the oil storage tank 4 can smoothly enter the oil supply hose 10 to lubricate a gear below. Meanwhile, the guide pin 22 also slides leftwards along with the piston rod, and as the guide pin 22 is slidably connected with the moving plate 18 through the guide inclined groove 21, the moving plate 18 can move upwards under the action of the guide pin 22, so that the extrusion rod 16 is driven to move upwards, and the extrusion block 19 is unlocked and fixed to the driving gear 2 (as shown in fig. 4). In a similar way, when the driving gear 2 stops rotating, only the piston rod of the telescopic cylinder 9 needs to move right, the oil baffle plate 8 and the extrusion block 19 can return to the original position (as shown in fig. 1), the driving gear 2 is ensured not to rotate accidentally, and meanwhile, the lubricating mechanism can stop oil supply, so that resources are saved.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
