Technical Field

[0001] The utility model relates to the technical field of gear transmission boxes, in particular to a gear transmission box. Background Art

[0002] Gearbox, also known as gearbox, is an important mechanical component widely used in the mechanical field. Common functions of gearbox include deceleration, changing transmission direction or torque, and power distribution. Among the causes of gearbox failure, insufficient lubrication accounts for more than half. The lubrication system of the gearbox is of great significance to the normal operation of the gearbox.

[0003] However, most of the gear transmission boxes on the market currently still have some shortcomings when lubricating gears. For example, most of the existing gear transmission boxes are not convenient for uniformly lubricating different positions of the gears, and are usually not convenient for filtering and recovering the lubricating oil, and the lubricating oil utilization rate is low, resulting in certain usage defects. Therefore, we propose a gear transmission box to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a gear transmission box, in which an oil inlet channel is opened in an inclined shape inside the transmission box body, and diverter holes are evenly distributed at the lower end of the oil inlet channel along the axial direction of the transmission gear set. Lubricating oil is added to the oil inlet channel through a refueling box, and the lubricating oil flows downward along the oil inlet channel and evenly flows to the outside of the transmission gear set through the diverter holes, so that lubricating oil can be evenly added to the transmission gear set along the axial direction of the transmission gear set, which facilitates uniform refueling and lubrication of different positions of the gears and improves the lubrication effect.

[0005] The utility model adopts the following technical solution: a gear transmission box, comprising a transmission box body and a transmission gear set arranged inside the transmission box body, the outer end surface of the transmission box body is integrally fixedly provided with a bearing seat, and the interior of the bearing seat is connected to a shaft sleeve, and the upper end surface of the transmission box body is fixedly connected to a refueling box;

[0006] An oil inlet channel is provided inside the transmission case body, and the lower end surface of the oil inlet channel is connected to a diversion hole provided inside the transmission case body. A drainage hole is provided inside the transmission case body, and an oil outlet pipe is fixedly connected to the lower end surface of the transmission case body, and the oil outlet pipe is connected to the inner cavity of the transmission case body through the drainage hole. An oil storage unit is connected to the outside of the oil outlet pipe, and a filter unit is provided inside the oil storage unit.

[0007] The oil storage unit includes a connecting tube connected to the outside of the oil outlet pipe, and the outer surface of the oil outlet pipe and the inner surface of the connecting tube are both provided with matching thread structures so that the oil outlet pipe and the connecting tube form a threaded connection;

[0008] The filter unit includes a filter cartridge arranged inside the oil storage box, and a convex edge is fixedly connected to the upper side of the outer surface of the filter cartridge in an integrated manner, and a filter screen is fixedly connected to the interior of the filter cartridge.

[0009] As a preferred technical solution of the present invention, the refueling box is connected to the transmission box body through an oil inlet channel, and a sealing cover is provided at the upper end of the refueling box.

[0010] As a preferred technical solution of the present invention, the oil inlet channel is opened in an inclined shape inside the transmission box body, and the diversion holes are evenly distributed at the lower end of the oil inlet channel along the axial direction of the transmission gear set.

[0011] As a preferred technical solution of the present invention, the oil storage unit further includes an oil storage box integrally fixedly connected to the lower end of the connecting cylinder, and a boss is provided inside the connecting cylinder.

[0012] As a preferred technical solution of the present invention, the filter cartridge is overlapped on the upper end surface of the boss via the convex edge, and the convex edge and the boss play a supporting role on the filter cartridge.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The oil inlet channel is inclinedly opened inside the transmission case body, and the diverter holes are evenly distributed at the lower end of the oil inlet channel along the axis of the transmission gear set. Lubricating oil is added to the oil inlet channel through the oil filling box. The lubricating oil flows downward along the oil inlet channel and evenly flows to the outside of the transmission gear set through the diverter holes. In this way, lubricating oil can be evenly added to the transmission gear set along the axis of the transmission gear set, making it convenient to evenly lubricate different positions of the gear and improving the lubrication effect.

[0015] 2. A drainage hole is opened inside the transmission case body, and the waste lubricating oil flows out of the inner cavity of the transmission case body through the drainage hole and is collected by the oil storage box. At the same time, a filter screen is fixedly connected to the inside of the filter cylinder, and the filter screen can filter the lubricating oil flowing into the oil storage box and leave impurities inside the filter cylinder. After use, the connecting cylinder is rotated to separate the connecting cylinder from the oil outlet pipe, and the lubricating oil inside the oil storage box can be recycled and reused, thereby improving the utilization rate of the lubricating oil and solving the problem that most existing gear transmission cases are not convenient for filtering and recycling lubricating oil and have low utilization rate of lubricating oil.
