Abstract
The utility model relates to the technical field of mechanical transmission devices, and particularly relates to a torque increasing chain in a mechanical transmission process. The torque increasing chain is characterized by comprising multiple inner chain sections and outer chain sections which are connected, wherein each inner chain section comprises two inner chain pieces; each outer chain section comprises two outer chain pieces; three top angles of each inner chain section and three top angles of each outer chain section are respectively provided with a pin hole, and a short pin shaft is arranged in each pin hole; a long pin shaft on the bottom edge of each inner chain section is connected with two pin holes in the bottom edge of the corresponding outer chain section, each chain section is of an equilateral triangle structure, and the two pin shafts of the bottom edge of each chain section only play the connection role while the pin shaft on the top corner of each chain section can drive a driven member to operate based on a lever principle so as to achieve the torque increasing effect. The device provided by the utility model is widely applied to a transmission machine.
Description
Technical field
The utility model relates to mechanical transmission technical field, particularly relates to the chain that increases moment of torsion in a kind of mechanical transmission course.
Background technique
Chain, as important mechanical basic part, is widely used in the every field of national economy.Because no matter chain transmission is for the transmission of power or the conveying of material, the lifting of weight and the traction of workpiece, all there is good usability, so the irreplaceable several functions of mechanical engineering bound pair chain transmission is reached common understanding.The chain strip adoption bar shaped chain sheet of prior art, bearing pin plays the effect of connection and driver link, because bearing pin directly contacts with sprocket, does not therefore increase and does not turn round effect.
Summary of the invention
The purpose of this utility model is to avoid prior art to reach to increase to turn round the defect of effect and to provide a kind of increasing to turn round chain, efficiently solves the problem that prior art exists.
For achieving the above object, the technological scheme that the utility model is taked is: chain is turned round in described increasing, be characterized in comprising a plurality of connected inner links and outer link, each inner link comprises two inner chain sheets, each outer link comprises two outer chain sheets, three drift angle places of inner chain sheet and outer link are respectively provided with a pin-and-hole, two pin-and-hole places on inner link base are respectively arranged with second axle and the 3rd axle of having strong market potential of having strong market potential, the pin-and-hole place of inner link drift angle is provided with short pin shaft, second axle of having strong market potential, the 3rd has strong market potential on axle and short pin shaft is provided with short cylinder, second of inner link base axle and the 3rd axle of having strong market potential of having strong market potential is connected with two pin-and-holes at place, adjacent outer link base respectively, the pin-and-hole at outer link drift angle place is provided with first axle of having strong market potential, have strong market potential on axle long cylinder is installed.
Distance between every two pin-and-holes on described inner chain sheet and outer link equals the pitch of chain.
Described inner link and outer link are equilateral triangle structure, and two bearing pins on inner link and outer link base only play connection function, and the bearing pin at inner link and outer link drift angle place utilizes lever principle to drive driven member work, plays the effect that increases moment of torsion.
The beneficial effects of the utility model are: chain is turned round in described increasing, its each chain link is equilateral triangle structure, two bearing pins on chain link base only play connection function, and the bearing pin at chain link drift angle place utilizes lever principle to drive driven member work, play the effect that increases moment of torsion.This device can be widely used in gearing.
