Abstract
The utility model relates to a novel driving speed change mechanism. Generally, a driving mechanism driven wheel rubs generate rotary slip easily with an outer wheel, due to factors in temperature changes and processing errors and the like which are driven by friction, joint driving slip is unavoidable. The novel driving speed change mechanism comprises a driving shaft (1) which is connected with a driven wheel (2) through friction, and the driven wheel is connected with an outer wheel in engaging style. The utility model is used for changing speed of a high-speed rotating shaft.
Description
Technical field:
The utility model relates to a kind of novel transmission shifting mechanism.
Background technique:
High speed rotating axle (motor rotor) need carry out speed change (increasing square) transmission for increasing torque and speed adaption.Usually driving mechanism follower and the foreign steamer friction slippage that easily rotates, because its factor at aspects such as temperature variation and machining errors of friction driving, joint transmission slippage is inevitable.For driving shaft, because its line footpath is less, the engagement driving characteristic is difficult to reach the speed stabilizing equilibrium.
Summary of the invention:
The purpose of this utility model provides a kind of little line footpath driving shaft and adopts friction mode to drive three followers, and three followers drive the novel transmission shifting mechanism that foreign steamer rotates with engagement system.
Above-mentioned purpose realizes by following technological scheme:
Novel transmission shifting mechanism, its composition comprises: driving shaft, described driving shaft connects follower by friction, and described follower connects foreign steamer with engagement system.
Described novel transmission shifting mechanism, described follower are three, and the axle of described three followers is fixedly installed to the chassis.
The beneficial effects of the utility model:
1. it is the gear ratio that reaches certain that this three-wheel two-stage variable transmission mechanism has solved driving wheel, generally bigger diameter dimension can not be arranged, number of meshes is less during engagement driving, be difficult to design the problem of the engaging mechanism that reaches certain performance index, thereby follower and foreign steamer are easy to realize meshing rotate the velocity ratio that reaches qualification, the rotating speed slippage that different followers produce when having overcome friction driving.
2. initiatively the axis footpath is little mainly is by reaching certain speed change (increasing square) than limit, but the temperature coefficient influence of simultaneously little line footpath is limited, and employing fricting transmissioning mode drive follower has overcome the directly shortcoming during engagement driving of little line.
