Abstract

The invention discloses a conical surface friction differential transmission. A conical sun wheel, three same conical planetary wheels, a rotating arm shaft and an outer ring are arranged in a casing, wherein the conical sun wheel is arranged at one end of a driving shaft; the other end of the driving shaft is arranged in a bearing hole in one end of the casing; one end of the rotating arm shaft is arranged in the bearing hole in the other end of the casing; three rotating arms are uniformly distributed at the other end of the rotating arm shaft; the conical planetary wheels are respectively arranged on planetary shafts of the rotating arms and respectively drive with an inner conical hole of the outer ring and the conical sun wheel by friction; the outer ring is fixed on the casing; the three conical planetary wheels rotate around respective shafts and simultaneously revolve around the sun wheel; and all extended lines of the conical surface are intersected at the same point of a transmission axis. According to the conical surface friction differential transmission disclosed by the invention, the power is transmitted by friction and the convenience for processing is realized; in addition, an equivalent coefficient of friction is increased by increasing the contact of the conical surface, so that the transmitted torque is increased. After the contacted surface is worn, the aim that the wear is complemented by axially translating the sun wheel or the planetary wheels is achieved.

Description

technical field [0001] The invention relates to a transmission, in particular to a conical surface friction transmission. Background technique [0002] The transmission is a gear transmission device that can change the transmission ratio of the output shaft and the input shaft to meet the needs of traction and speed under different conditions. Gears are generally made of high-quality low-carbon alloy steel for carburizing and quenching, which requires high precision and complicated processing and manufacturing. Since transmission gears are often working under changing speed and load, and the tooth surface of the gear is impacted by the impact load, the gear (especially the tooth surface) is prone to damage, such as: gear wear, gear teeth broken, etc., need to be often Change the gear. Contents of the invention [0003] The purpose of the present invention is to provide a kind of conical surface friction speed changer, the sun gear and the planetary gear are made into a c...
