[0002] A reducer is an independent component consisting of a gear drive, a worm drive, or a gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. The shaft-mounted arc cylindrical worm reducer adopts a worm gear tooth shape and a conjugated worm. It is widely used in the reduction mechanism of transmission machinery in metallurgy, mining, lifting, transportation, chemical industry, construction, building materials, and light industry. It has the advantages of large transmission ratio, large load-bearing capacity, high transmission efficiency, reliable use, and long service life.

[0003] In the current worm reducers, deceleration is achieved only through a simple transmission of a worm wheel and a worm meshing, which is usually set up in a vertical axis. When in use, multiple transmission direction-changing devices are required, which have a complex structure, reduce transmission efficiency, and increase the floor space occupied by the reducer during operation, making it less practical.

[0007] The top of the first bevel gear is meshedly connected with the second bevel gear, and the bottom end of the second bevel gear is transmission-connected with the output rod through the third bevel gear, and the output rod is arranged in parallel with the worm.

[0008] As a further description of the above technical solution:

[0009] The output rod is installed inside the housing through a bearing, and the output rod is arranged to penetrate through the housing on one side of the worm.

[0010] As a further description of the above technical solution:

[0011] The output rod and the rotating rod are arranged vertically, and the rotating rod and the worm are arranged vertically.

[0012] As a further description of the above technical solution:

[0013] The second bevel gear is rotatably connected to the inner top wall of the housing through a rotating rod, and the axis of the second bevel gear is perpendicularly arranged to the horizontal axis of the worm gear.

[0014] As a further description of the above technical solution:

[0015] The worm gear and the second bevel gear are arranged inside the fixed housing, and a movable housing is installed on the other side of the fixed housing through bolts.

[0016] As a further description of the above technical solution:

[0017] The worm and the housing are connected via an oil seal.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] In the utility model, a worm gear is arranged inside the shell, and a first bevel gear is arranged at one end of the rotating rod. Through the meshing connection between the second bevel gear and the third bevel gear, the third bevel gear can realize transmission output, thereby realizing the same-direction reduction output of the reducer. The utility model has a compact structure, simple and convenient internal maintenance, and reduces the use cost of the reducer. It also has a wide range of applications and strong practicality.
