Abstract
The utility model relates to a speed reducer for a planet friction wheel, which is composed of an input shaft, a following shaft, an eccentric sleeve, a planet wheel, a ferrule, an output shaft, a machine body cover and a machine base. The utility model is characterized in that the planet wheel uses two eccentric opposite cone-shaped friction wheels which are contacted with the inner cone surface of the ferrule with certain pressure, the transmission of motion and power are realized by frictional force, and a high speed ratio is obtained by a short eccentric distance of the planet wheel. The utility model has the advantages of simple structure, good manufacturability, high speed ratio, low noise, low material requirement, low cost, etc., and besides, the utility model is an economical transmission device suitable for medium and low power.
Description
The utility model is a kind of transmission device, belongs to universal machine.
Domestic and international existing large speed ratio retarder, adopt lacked tooth difference involute planet gear or cycloidal-pin wheel transmission (seeing each speed reducer factory catalogue) more.Its structure, manufacturing process complexity, the requirement height to material causes cost higher, and is difficult to make at general semiworks.
The utility model aim to provide a kind of simple in structure, easy to manufacture, to the large speed ratio retarder that material requirements is not high, cost is low and just can make at general semiworks.For this reason, replace involute or cycloidal gear as planet wheel with friction wheel, replace internal gear or pinwheel with lasso, changing engagement driving is friction driving, and has cancelled the W mechanism that is used to export, and is imported by the input shaft of biasing.So just make structure, work simplification, just can make with conventional process means and equipment.
(Fig. 1) illustrates working principle of the present utility model and working procedure below in conjunction with accompanying drawing.

The utility model is made up of input shaft (2), servo axis (1), eccentric bushing (4), planet wheel (6,7), lasso (5), output shaft (10), machine body cover (3) and support (9) etc.The input shaft of biasing and servo axis and eccentric bushing, planet wheel, machine body cover are formed parallelogram lindage, when input shaft rotates, and planet crop rotation translation.Two planet wheels adopt cone friction wheel, and they contact with the inner conical surface of lasso, and pressure is therebetween regulated (by the window on the support) by nut (8), also can use the spring pressurization instead.Therefore when the planet wheel translation, just frictionally drives the lasso rotation that connects firmly with output shaft, and obtains the large speed ratio transmission by the small eccentricity of planet wheel.
The utility model is simple in structure, good manufacturability, speed ratio is big, noise is little,, low price not high to material requirements.Because the frictionally transmission is so it also has overload protection function.When using the spring pressurization instead, but its double as clutch use again.The utility model is applicable to and requires large speed ratio, but the validity of speed ratio is required not tight middle low power transmission occasion.
Claims (3)
1, a kind of novel planetary friction wheel retarder, form by input shaft, servo axis, eccentric bushing, planet wheel, lasso, output shaft, machine body cover and support, wherein Pian Zhi input shaft and servo axis and eccentric bushing, planet wheel, machine body cover are formed parallelogram lindage, lasso and output shaft connect firmly, it is characterized in that two planet wheels adopt friction wheel, they contact with the internal surface of lasso, and pressure is therebetween regulated by pressurization device.
2, retarder according to claim 1 is characterized in that two planet wheels adopt cone friction wheel, and the internal surface of lasso is the conical surface.
