The purpose of this utility model is the deficiency that interior external gear can not be set in order to make up prior art simultaneously, and a kind of single raceway twin tooth type pivoting support is provided.
The technical solution of the utility model is as follows:
A kind of single raceway twin tooth type pivoting support, include inside and outside circle, it is characterized in that: the top of described inside and outside circle junction plane is provided with ring-type tubular shape or ring-type square-tube-shaped raceway, in described ring-type tubular shape or ring-type square-tube-shaped raceway, be provided with rolling element, on the bottom of described inner ring inwall and outer ring outer wall or on inner ring inwall and the bottom of outer ring outer wall has respectively inside and outside gear.
Described single raceway twin tooth type pivoting support, is characterized in that: described rolling element is steel ball, roller or ordered fabrication steel ball and roller together.
Described single raceway twin tooth type pivoting support, is characterized in that: on described inner ring or outer ring, be respectively equipped with filling hole and tank filler sleeve.
Described single raceway twin tooth type pivoting support, is characterized in that: between described inside and outside circle junction plane, be respectively equipped with seal ring at the upper and lower of ring-type tubular shape or ring-type square-tube-shaped raceway.
Described single raceway twin tooth type pivoting support, is characterized in that: on the end face of described inside and outside circle, be respectively equipped with mounting hole.
Described single raceway twin tooth type pivoting support, is characterized in that: described roller is that slightly larger in diameter is in the short cylinder of height.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, can on the inside and outside circle of the pivoting support of single roller path structure, internal gear and external gear be set simultaneously, and the main process equipment that applicable needs carry out the two power transmissions of Internal and external cycle adopts.
