Problems solved by technology

[0002] Orthogonal harmonic drive reducer has been widely used in various fields in various industries due to its large reduction ratio, small size, light weight, large output torque, and high transmission accuracy. However, its orthogonal harmonic The transmission reducer is affected by the two-stage transmission and the harmonic deformation wave, and the transmission efficiency of its products cannot be improved. The efficiency of the single-stage harmonic reducer is only about 75%. The efficiency is only about 50%. For some users who require high transmission efficiency, it must be subject to certain restrictions and certain defects.

Embodiment Construction

[0010] specific implementation

[0011] As shown in the figure, this orthogonal planetary reducer includes a high-speed motor input, a first-stage bevel gear reduction transmission pair, and a second-stage planetary transmission reduction transmission. The first-stage bevel gear transmission includes: a small bevel gear 3 and a large bevel gear 5, the small bevel gear 3 is fastened on the motor shaft through a cylindrical pin, the motor 1 drives the small bevel gear 3 to rotate, and the small bevel gear 3 passes through the positive The alternating mode drives the large bevel gear 5, thereby realizing the first-stage deceleration. The large bevel gear structure has an eccentric structure, and is connected with the planetary gear (duplex gear) 6 through the bearing; the two-stage planetary transmission deceleration includes: through the large bevel gear with eccentric structure The bevel gear 5 drives the double planetary gear 6 to rotate. The rotation of the planetary gear 6 i...

Abstract

The invention aims to provide an orthogonal planetary speed reducer transmission device, which overcomes the defects of transmission efficiency and service life in an orthogonal harmonic transmission speed reducer. The orthogonal transmission of a novel motor is realized by a pair of orthogonally engaged bevel gears, a large bevel gear with an eccentric structure drives a dual planetary wheel to rotate, the planetary wheel does circumferential movement around a fixed axis and also does rotary movement around a self axis, the planetary wheel and an inner gear are in the engagement transmission of one pair of gears with small tooth difference, and a sun gear is used as an output mechanism and is simultaneously engaged with the other gear of the planetary gear also in the engagement output of one pair of gears with small tooth difference. The orthogonal planetary speed reducer has the advantages that the speed reduction ratio is large, the size is small, the weight is light, the output torque is large, the transmission precision is high, the transmission efficiency is high, the service life is long, and the like.

technical field [0001] The invention relates to a planetary reducer transmission device for an orthogonal steering gear. Background technique [0002] Orthogonal harmonic drive reducer has been widely used in various fields in various industries due to its large reduction ratio, small size, light weight, large output torque, and high transmission accuracy. However, its orthogonal harmonic The transmission reducer is affected by the two-stage transmission and the harmonic deformation wave, and the transmission efficiency of its products cannot be improved. The efficiency of the single-stage harmonic reducer is only about 75%. The efficiency is only about 50%. For some users who require high transmission efficiency, it must be limited and has certain defects. [0003] Orthogonal planetary reducer design is also realized by two-stage reduction mechanism, the first stage is also a bevel gear transmission mechanism, and the other stage is a single-wave planetary eccentric reduct...
