The invention discloses an inner meshing worm and worm wheel transmission device with enveloped rollers. The transmission device comprises a worm, a power input shaft, a plurality of worm wheels, and power output shafts installed on the worm wheels. The worm is of a hollow semi-spherical structure. A worm throat is arranged in the middle of the worm. One end of the power input shaft is installed in the worm throat. An inner meshing face is arranged on the inner wall of the worm. Outer meshing teeth matched with the inner meshing face on the worm are uniformly arranged on the outer wall of each worm wheel. The worm wheels are installed in an inner cavity of the worm. The outer meshing teeth are meshed with the inner meshing face. The worm drives the worm wheels to rotate under driving of the power input shaft. The transmission device is compact in structure, small in size, light in weight, high in transmission efficiency and good in lubricating performance, and achieves multi-load output.
Description
technical field [0001] The invention belongs to the field of worm gear transmission, in particular to a roller enveloping inner meshing worm gear transmission device. Background technique [0002] As one of the types of gear transmission, the worm and worm gear transmission is mainly used to transmit the power and motion between the two shafts that are staggered in space. Due to its compact structure, large transmission ratio, low noise and large output torque of the worm gear widely used. However, with the development of productivity and industrial technology, there is a contradiction that the existing worm drive technology cannot meet the actual production. The worm drive reducer that adopts the traditional external meshing form has problems such as large volume, heavy weight, and low transmission efficiency, so it is more and more unable to meet the development needs of modern production technology, especially aerospace and missile submarines. The development needs of s...
