Abstract
The utility model discloses an apparatus for reducing the friction of a transmission shaft, which comprises an inner sleeve and an outer sleeve, wherein at least one middle sleeve is installed between the inner sleeve and the outer sleeve, a first annular support frame is installed between the inner sleeve and the middle sleeve, and a plurality of rollers are installed on the first annular support frame; a second annular support frame is installed between the middle sleeve and the outer sleeve, and a plurality of rolling pieces are installed on the second annular support frame. The utility model is provided with at least three layers of sleeves capable of oppositely rotating, and the rolling pieces are installed among the sleeves, so the utility model can effectively reduce the friction force between a transmission shaft and a supporting object thereof, enhance the transmission efficiency of the transmission shaft and reduce the energy loss in the process of transmission. The apparatus for reducing friction of transmission shaft has the advantages of simple structure, convenient installation and use and low cost.
Description
Technical field
The utility model relates to mechanical field, exactly is a kind of device that reduces the transmission shaft friction.
Background technique
In the middle of mechanical field, the application of transmission shaft is very extensive.The major function of transmission shaft is to transmit torque, and in the transmission process, the friction between transmission shaft and its bearing object is the principal element that influences the transmission shaft transmission efficiency, and the big more transmission efficiency of the friction in the transmission shaft transmission process is just low more, and energy loss is also big more.For the people that reduce friction install bearing between transmission shaft and its bearing object, still, the transmission shaft that existing bearing only adapts to low speed rotation uses, and but can't satisfy the usage requirement of high-speed drive shaft.
Summary of the invention
The purpose of this utility model has provided a kind of device that reduces transmission shaft friction, and its is fit to all transmission shafts of low speed and high speed transmission, and compare it to have gearing friction power little with bearing, and the advantage that energy loss is low can solve
The problem that prior art exists.
The purpose of this utility model is achieved through the following technical solutions: a kind of device that reduces the transmission shaft friction, cover and overcoat in it has, interior cover and outer inner room are installed a middle cover at least, between interior cover and middle cover first ring support is installed, a plurality of rollers are installed on first ring support, middle cover and outer inner room are installed second ring support, and a plurality of roll pieces are installed on second ring support.
For further realizing the purpose of this utility model realizing by the following technical solutions: annular groove in the first outer ring groove and first is offered in the inside and outside both sides of middle cover.The second outer ring groove is offered in the interior cover outside.Annular groove in second annular is offered in the overcoat inboard.Annular groove in second annular is offered in the overcoat inboard.Roller is the identical ball of structure with roll piece.Roller is the identical roller of structure with roll piece.
Good effect of the present utility model is: it has at least three layers of relatively turnable cover, and inner room is installed roll piece, can reduce the frictional force between transmission shaft and its bearing object effectively, improves the transmission efficiency of transmission shaft, the energy loss in the minimizing transmission process.It also has advantage simple in structure, easy to install, cheap for manufacturing cost.
