Abstract

The invention provides a uniform load floating mechanism with a regulable floating quantity for a planetary gear. The uniform load floating mechanism comprises a planetary frame, a baffle, spacers, a central shaft, a sun wheel and a planet wheel, wherein the sun wheel and the planet wheel are positioned between the planetary frame and the baffle; the planetary frame is connected with the baffle through screws; one end of the central shaft is connected with the planetary frame through a rolling bearing, and the other end of the central shaft penetrates through the center of the baffle; the sun wheel and the planet wheel are conical gears, and the large head end of the sun wheel and the large head end of the planet wheel are in opposite directions and mutually meshed; the spacers sleeve the central shaft and are positioned on two sides of the sun wheel. The uniform load floating mechanism disclosed by the invention is simple in structure, small in size and light in weight; the horizontal position of the center of the sun wheel is changed through changing the number of the spacers on the two sides of the sun wheel by the conical gears in the operation process of the floating mechanism, then a gap between the sun wheel and the planet wheel is changed, and staged regulation of the gap between the gears can be realized, so that the continuous regulation of the floating quantity of the sun wheel is realized.

Description

technical field [0001] The invention relates to a gear equalizing mechanism, in particular to a planetary gear equalizing floating mechanism with adjustable floating amount. Background technique [0002] The reason why the planetary gear transmission has the advantages of small size, light weight, and high load-carrying capacity is mainly due to the fact that multiple planetary gears are used to share the load on average to form a power split, and the internal meshing is used reasonably, so the load between the planetary gears is evenly distributed. . There are two schemes to achieve uniform load sharing between planetary gears. The first is to improve the processing and installation accuracy of main parts such as gears and planetary carriers. However, due to the limitations of equipment, technology, cost and many other conditions, the general conditions are difficult to achieve, and it is very uneconomical. The second is to adopt a "load equalization mechanism" from the s...
