Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] like Figures 1 to 5 As shown, the utility model discloses a lubricating reducer, including a reducer housing 11, an input shaft 15 and an output shaft 17 are rotatably connected to the reducer housing 11, a torque transmission gear assembly is arranged between the input shaft 15 and the output shaft 17 inside the reducer housing 11, one end of the output shaft 17 penetrates the reducer housing 11, and both ends of the input shaft 15 penetrate the reducer housing 11, a power source connecting piece is arranged at one end of the input shaft 15, and the power source connecting piece is a pulley 16, and the pulley 16 is fixedly connected to the input shaft 15. When the utility model is used, it needs to be matched with a motor, and another pulley is connected to the shaft of the motor. The two pulleys The wheels are matched with each other through a belt, so that when the motor rotates, the input shaft 15 can be driven to rotate synchronously. In addition, in the utility model, the reducer housing 11 is provided with a pump body 21 at the other end of the input shaft 15, and the pump body 21 is provided with an impeller 22, and the input shaft 15 penetrates into the pump body 21 and is fixedly connected to the impeller 22, and a lubricating oil inlet 211 and a lubricating oil outlet 212 are provided on the pump body 21, and an oil inlet pipe 111 corresponding to the torque transmission gear assembly is provided on the upper side of the reducer housing 11, and a conveying pipeline 3 is connected between the lubricating oil outlet 212 and the oil inlet pipe 111, and an oil outlet pipe 112 is provided at the bottom of the housing.

[0023] In the present invention, a lubricating oil tank is connected to the lubricating oil inlet 211 of the pump body 21, and the lubricating oil tank can supply oil to multiple reducers at the same time. In addition, the oil outlet pipe 112 at the bottom of the reducer housing 11 is also connected to the lubricating oil tank, and a filtering device for filtering the lubricating oil and other pump bodies for conveying the lubricating oil are provided between the oil outlet pipe 112 at the bottom of the reducer housing 11 and the lubricating oil tank, so that the lubricating oil can be reused, and it is only necessary to add the lubricating oil in the lubricating oil tank at a certain time. Since the lubricating oil tank and the filtering device are common knowledge in the field, the present application does not involve improvements to their internal structures, so they will not be described in detail here.

[0024] In addition, the torque transmission gear assembly specifically includes a worm 151 fixedly connected to the input shaft 15 and a turbine 18 fixed to the output shaft 17, the worm 151 is meshed with the turbine 18, wherein the turbine 18 is located on the upper side of the worm 151, and the oil inlet pipe 111 is correspondingly arranged on the upper side of the turbine 18.

[0025] The working principle of the utility model is as follows: when the motor drives the input shaft 15 to rotate, the input shaft 15 drives the turbine 18 through the worm 151, thereby rotating the output shaft 17, and the input shaft 15 will drive the impeller 22 of the pump body 21 to rotate at the same time, so the lubricating oil in the lubricating oil tank enters from the lubricating oil inlet 211 and is pumped out from the lubricating oil outlet 212, and then enters the oil inlet pipe 111 through the delivery pipe 3, and is poured on the turbine 18. The engagement of the turbine 18 with the worm 151 will also make the lubricating oil reach the worm 151, and the lubricating oil reaching the bottom of the reducer housing 11 flows out from the oil outlet pipe 112, and returns to the lubricating oil tank after being filtered, and the cycle continues in this way. As long as the reducer is working, the lubricating oil can continuously lubricate its internal turbine 18 and worm 151. Of course, if the torque transmission gear assembly is replaced with other gear sets, it can also be lubricated.

[0026] Furthermore, the pump body 21 is fixedly connected to the reducer housing 11 via a flange, and the reducer housing 11 is provided with a skeleton oil seal 13 and a bearing 14 at both ends of the input shaft 15. This structure ensures that the input shaft 15 can rotate stably and at high speed and prevents the lubricating oil inside the reducer housing 11 from leaking.

[0027] In addition, the pump body 21 is provided with a second skeleton oil seal 23 that cooperates with the input shaft 15 on the side close to the reducer housing 11. The pump body 21 is also provided with a mechanical seal 24 located between the second skeleton oil seal 23 and the impeller 22. This structure is used to prevent the lubricating oil in the pump body 21 from leaking.

[0028] like Figure 4As shown, an oil groove 113 is provided at the bottom of the reducer housing 11, an oil outlet pipe 112 is located at one end of the oil groove 113, and an oil drain port 114 penetrating the housing is provided at the other end of the oil groove 113, a plug 12 is provided in the oil drain port 114, and this structure allows the lubricating oil in the reducer housing 11 to be manually drained from the oil drain port 114 when the plug 12 is removed during maintenance.
