Bearing type universal chain

Abstract

The invention discloses a bearing type universal chain. The bearing type universal chain comprises at least two unit rail links which can rotate relatively and cross shaft connecting pieces used for connecting the adjacent unit rail links. Each unit rail link comprises two walking devices and cross shaft frames which are connected with the two walking devices. The core component of each walking device is a cross shaft, wherein horizontal rotation and vertical rotation can be realized through a longitudinal shaft and a transverse shaft of each cross shaft. The bearing type universal chain has the advantages that each unit rail link is formed through the two cross shafts, the longitudinal shafts of the cross shafts, close to each other, of every two adjacent unit rail links are connected through the corresponding cross shaft connecting piece, rotation of the two adjacent unit rail links in the horizontal direction is realized, the transverse shafts of the two cross shafts of the same unit rail link are connected through the corresponding cross shaft frames, the two ends of each cross shaft frame and the two ends of the corresponding cross shafts are matched in a sleeved mode, relative rotation of the two cross shafts of the same unit rail link in the vertical direction is realized, and power transmission of the chain in three-dimensional space is realized in cooperation with a rail or a tension device at a turning position or a direction-changing position.

Description

technical field [0001] The invention relates to the technical field of chains capable of carrying loads and transmitting power. Background technique [0002] In the prior art, the chain that cooperates with the sprocket is a component that transmits the rotational motion of one side in the same plane to the other side to realize power transmission. The structure of the existing chain includes: a plurality of chain links, chain plates and a plurality of pin shafts are respectively provided on the two outer surfaces of adjacent chain links; the structure of the chain links is: fixed between two mutually parallel chain link plates Two chain rollers are spaced apart and arranged in parallel. The central through hole of the chain roller runs through the two chain link plates; the pin shaft hinges through the chain roller on the chain link, and its two ends are respectively fixed in the through holes of the chain plate , a plurality of chain plates are located on the outermost si...

The structure of the existing chain includes: a plurality of chain links, chain plates and a plurality of pin shafts are respectively provided on the two outer surfaces of adjacent chain links; the structure of the chain links is: fixed between two mutually parallel chain link plates Two chain rollers are spaced apart and arranged in parallel. The central through hole of the chain roller runs through the two chain link plates; the pin shaft hinges through the chain roller on the chain link, and its two ends are respectively fixed in the through holes of the chain plate , a plurality of chain plates are located on the outermost side of the chain, pin shafts are respectively fixed in the through holes at both ends of each chain plate, and the pin shafts are hinged in the chain rollers of the chain links, so that multiple chain plates and multiple pin shafts will Multiple links are hinged to form the existing chain. The existing chain has the following defects: the existing chain can only transmit motion in the same plane, and cannot complete synchronous linkage transmission in three-dimensional space. It needs to be realized by means of gears or other mechanisms, and there is a huge defect in the transmission system. At the same time, the existing chain can only transmit power, and cannot directly carry loads for transportation, so the scope of application is narrow
