[0002] A reducer is an independent component consisting of a gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine and is widely used in modern machinery. Reducers are generally used for low-speed and high-torque transmission equipment. The power of an electric motor, internal combustion engine, or other high-speed operation is decelerated by meshing the small gear on the input shaft of the reducer with the large gear on the output shaft.

[0003] The existing helical gear reducer mainly includes a housing and a multi-stage gear shaft. The multi-stage continuously meshing gear shaft is installed in the inner chamber of the housing. An oil filling hole connected to the inner chamber is opened on the top surface of the housing. During operation, workers drip lubricating oil into the gear shaft in the inner chamber through the oil filling hole on the top of the housing to reduce the wear of the gear shaft. Manual oiling is troublesome, and the lubricating oil will drip along the gear and deposit at the bottom of the housing. The lubricating oil needs to be cleaned, which is troublesome.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a power-assisted starting helical gear reducer, comprising a shell 1, in which a first-stage pinion 4, a first-stage large gear 5 and a second-stage large gear 7 are rotatably matched, an input shaft 2 is fixed to the axis of the first-stage pinion 4, a second-stage gear shaft 6 is fixed to the axis of the first-stage large gear 5, and an output shaft 3 is fixed to the axis of the second-stage large gear 7. A bottom plate 8 is arranged at the bottom of the shell 1, an oil receiving groove 9 is provided in the bottom plate 8, two oil tanks 11 are arranged at the top of the shell 1, an oil outlet is provided at the bottom of the oil tank 11, a first blocking block 10 is elastically matched in the oil outlet, a plurality of swivels 13 are arranged on the input shaft 2 and the output shaft 3, and the first blocking block 10 corresponds to the swivel 13.

[0023] In this embodiment, the housing 1 is rotatably connected to the input shaft 2 and the output shaft 3, and the housing 1 is slidably connected to the bottom plate 8. The oil receiving groove 9 is a funnel-shaped structure, and an oil receiving port is opened at the bottom of the oil receiving groove 9. A second blocking block 12 is installed in the oil receiving port.

[0024] Specifically, the dripping lubricating oil can be caught by the oil collecting groove 9, and the funnel-shaped structure can collect the lubricating oil. When the lubricating oil needs to be cleaned and recovered, the second blocking block 12 can be removed to allow the lubricating oil to flow out from the oil receiving port, thereby collecting the lubricating oil, and the bottom plate 8 can be directly slid out, thereby facilitating the cleaning of the surface of the bottom plate 8.

[0025] The first-stage small gear 4 meshes with the first-stage large gear 5 , and the second-stage large gear 7 meshes with the second-stage gear shaft 6 . A partition plate 17 is fixed in the housing 1 , and the partition plate 17 is rotatably connected to the input shaft 2 and the output shaft 3 .

[0026] Specifically, when the reducer is used, the input shaft 2 drives the primary pinion 4 to rotate, the primary pinion 4 meshes and rotates with the primary large gear 5, the primary large gear 5 drives the secondary gear shaft 6 to rotate, the secondary large gear 7 meshes and rotates with the secondary gear shaft 6, thereby driving the output shaft 3 to rotate, and the reduced speed output can be achieved.

[0027] The relative inner side of the swivel 13 is a frosted structure. The swivel 13 is rotatably connected to the input shaft 2 and the output shaft 3. Connecting rods 15 are fixed on both sides of the first block 10. A plurality of springs 16 are fixed between the connecting rod 15 and the box wall of the oil tank 11. A pull rod 14 is installed between the swivel 13 and the connecting rod 15. Both ends of the pull rod 14 are rotatably connected to the swivel 13 and the connecting rod 15 respectively.

[0028] Specifically, when the input shaft 2 and the output shaft 3 rotate, the friction between the input shaft 2 and the output shaft 3 and the swivel 13 will drive the swivel 13 to rotate a certain angle, so that the swivel 13 pulls the pull rod 14, and the pull rod 14 pulls the connecting rod 15, thereby driving the first block 10 to move downward and the spring 16 is squeezed. When the input shaft 2 and the output shaft 3 stop rotating, the spring 16 rebounds, so that the connecting rod 15 pushes the first block 10 to move upward. At this time, the lubricating oil can flow downward through the oil outlet, and as the spring 16 tends to be stable, the first block 10 will block the oil outlet again to prevent waste of lubricating oil.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
