Thin wall bearing production method

Epicycloid motivation or planetary gear transmission system in a small space is designed to achieve bigger slowdown. Its simple structure as shown in figure 4. 20. P R is for internal gear in this diagram, on behalf of the planetary wheel, S round the sun. The sun wheel linked to check into the shaft, output shaft and connecting rod. Institutions are usually consists of three or more of the planet wheel, therefore, each planet gear shaft passing 1/3 or less power. Through the figure 4. 20, you can see the sun wheel relative to the speed of the connecting rod for n = n3 - n，。 Internal gear relative to the connecting rod R ( Speed is n = - N, thus connecting rod A e = = ( 4. 61). Now, keep the link static, allowing the internal gear rotating, application type ( 4. 60) ( 4. 62). Type ( 4. 62). The minus sign indicates that the internal gear ( Output) The direction of rotation and the sun in figure 4. 20 simple planetary gear structure schematic ( Input) In the opposite direction. A n = 0, use the type ( 4. 61). Type ( 4. 62). To said output shaft speed, the planetary wheel shaft speed can be determined by type + 1 ( 4. 63). There are many different kinds of ps planet gear mechanism that is given to the speed of each structure calculation formula is impossible. Above, puts forward the calculation method is effective and can be applied in practice. 4. 5 distributed load system, and sometimes load distribution on the axis of a certain period, as shown in figure 4. 21. If the load is irregular, to put it as a series of tiny load P. Composition. P the distance from the left end bearing is a1, can use type ( 4. 9) Type ( 4. 10) To gauge the bearing load F and F2. When the unit length on the distribution of load can be expressed as a continuous function
