Problems solved by technology

The disadvantage is that the inertial load acting on the crankshaft of the two-stage cycloidal wheel is difficult to completely balance, which seriously affects the dynamic performance and working reliability of the reducer. Due to the particularity of the structural design, the assembly performance of the whole machine is poor.

Example Embodiment

[0017] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described are only for explaining the present invention and are not intended to limit the present invention.

[0018] The present invention proposes a compound cycloid reducer, such as figure 1 As shown, the input shaft 1, the fixed pin gear housing 12 and the output pin gear housing 13 are included.

[0019] The input shaft 1 is an eccentric shaft with three eccentric positions, including a middle eccentric section and eccentric sections on both sides. Of the eccentric sections on both sides, the left side is the input side eccentric section, and the right side is the output side eccentric section. The input side The eccentric section is equipped with a first-stage left cycloidal gear 41, and the middle eccentric section is equipped with a first-stage right cycloidal gear 42 and a second-sta...

Abstract

The invention discloses a compound cycloid reducer, which comprises an input shaft, a fixed pin gear housing and an output pin gear housing, the input shaft is an eccentric shaft with three eccentric positions, and the eccentric sections of the three eccentric positions are respectively equipped with two-stage cycloid wheels , Each stage of transmission adopts a layout of two cycloidal wheels misaligned by 180 degrees. In the radial direction, radial needle roller bearings are used to connect and support the fixed pinion housing and the output pinion housing; in the axial direction, thrust needle roller bearings are used to connect and support the fixed pinion housing and the output pinion housing ; The four cycloidal wheels are provided with evenly distributed pin holes and simultaneously penetrated with pins, and the pins are connected with the pin holes through pin sleeves. The pin-tooth pins are inlaid on the fixed pin-tooth housing and the output pin-tooth housing respectively, and each stage of the cycloid wheel is meshed with the pin-tooth pins. The present invention adopts the above-mentioned two-stage cycloidal pin wheel compound transmission structure design, has the advantages of large load capacity, wide speed ratio range and compact structure, and is especially suitable for the transmission of robots, precision machine tools and medical equipment.

Description

technical field [0001] The invention relates to a cycloid reducer, in particular to a compound cycloid reducer. Background technique [0002] The cycloid reducer has many advantages such as large transmission ratio, high transmission efficiency, high transmission precision, high torsional rigidity and long life, so it is widely used in the field of precision mechanical transmission. The ordinary cycloidal reducer is equipped with a double eccentric sleeve with a misalignment of 180° on the input shaft, and two arm bearings are installed on the eccentric sleeve to form an H mechanism. The center hole of the two cycloidal wheels is the raceway of the arm bearing on the eccentric sleeve, and the cycloidal wheel meshes with a set of circularly arranged pin teeth on the pin gear to form an internal meshing deceleration with a tooth difference of one tooth. mechanism. [0003] The Taiwan Institute of Industrial Technology proposed an invention patent for a new transmission struc...
