Embodiment Construction
[0018] The present invention will be described in further detail below in combination with specific embodiments.
[0019] like figure 1 , figure 2 As shown, a rolling worm gear includes a worm wheel 1, a worm 4, a ball 6 and a ball raceway 2 arranged on the worm; One end of the spiral raceway is connected to one end of the communication raceway, and the other end of the spiral raceway is connected to the other end of the raceway, thus forming a smooth cycle. The ball raceway; a group of balls capable of circulating and rolling in the ball raceway are arranged in the ball raceway. The rim 5 of the worm wheel 4 is arranged in an arc shape corresponding to the outer circle of the worm 1, and the arc rim 5 of the worm wheel 4 is provided with a ball rolling groove 6 corresponding to the spiral ball raceway 2 on the surface of the worm 1 , when the worm 1 rotates, the balls 3 in the helical ball raceway 2 on the surface of the worm 1 can fit with the ball groove 6 on the arc-sh...

The invention relates to a worm pair. A spiral ball raceway is arranged on a surface of a worm; one spiral end of the ball raceway goes into the worm in a smooth shape and goes out of the worm to a surface of the worm in the smooth shape to communicate with the other spiral end of the ball raceway, and therefore, a smooth circulating ball raceway is formed; a group of balls capable of circularly rolling in the ball raceway is arranged in the ball raceway; a flange of a worm wheel is arranged into an arc corresponding to a shape of a top circle of the worm, and a ball rolling groove corresponding to the spiral ball raceway on the surface of the worm is formed in the arced flange of the worm wheel. According to the worm pair, through embedment of the balls in the ball raceway between the worm and the worm wheel, the balls roll in a space formed by the ball raceway and the ball rolling groove to realize transmission of the worm to the worm wheel; sliding friction is transformed into rolling friction, and therefore, the transmission efficiency is improved remarkably.
Description
technical field [0001] The invention relates to a worm gear, in particular to a rolling worm gear. Background technique [0002] Worm gear transmission is widely used in mechanical equipment, testing instruments and other fields. But it also has shortcomings and deficiencies, mainly because the transmission efficiency is relatively low, and there is also the phenomenon of low-speed crawling in addition. In the worm gear transmission, corresponding threads are provided on the surface of the worm and the rim of the worm wheel, and the transmission of the active worm to the driven worm is realized through the meshing of the worm thread teeth and the worm wheel thread teeth. Among them, the push of the thread teeth of the worm to the thread teeth of the worm gear is realized during the sliding friction meshing process of the two, so the transmission efficiency is relatively low. Contents of the invention [0003] The technical problem to be solved by the present invention is...
