Wheel diameter difference member speed reducer

Abstract

The invention discloses a wheel diameter difference member speed reducer. The wheel diameter difference member speed reducer comprises a wheel diameter difference member frame, a fixing main casing wheel, wheel diameter difference members and a differential motion casing wheel; the wheel diameter difference members are fixed inside the wheel diameter difference member frame in a rotary mode; the wheel diameter difference members are in transmission enragement with the fixing main casing wheel and the differential motion casing wheel; the wheel diameter difference member frame and the differential motion casing wheel can be input and output shafts; the wheel diameter difference member frame, the fixing main casing wheel and the differential motion casing wheel are arranged coaxially. The wheel diameter difference member speed reducer difference member speed reducer has the advantages of being simple in structure, low in machining difficulty, large in output power, strong in shock resistant capability and large in speed reducing range.

Description

[0001] The invention relates to a reducer, in particular to a radial differential reducer. Background technique [0002] The existing reducers mainly include: planetary reducer, worm gear reducer, cycloid reducer and harmonic reducer. The planetary gear reducer has a small reduction ratio range, the worm gear reducer is a surface contact friction transmission, the friction transmission speed is limited (not exceeding 1500r / min), and the reduction ratio range is not large; the cycloidal gear reducer is a surface contact multi-teeth meshing without friction Transmission, high transmission precision, durable, but its crankshaft structure is an unbalanced movement that is prone to vibration, and the output is a pinhole clearance fit connection that is not compact and impact-resistant; the RV type cycloidal gear reducer is a multi-swing disc and multi-crankshaft type. Balanced motion, compact structure, strong impact resistance, but its complex structure, large volume, high process...
