1, when

The time, by the cycloid equation $\left\{\begin{array}{c}y=d\mathrm{Cos}\left(\mathrm{N\θ}\right)+(R+r)\mathrm{Cos}\left(\mathrm{M\θ}\right)\\ x=d\mathrm{Sin}\left(\mathrm{N\θ}\right)+(R+r)\mathrm{Sin}\left(\mathrm{M\θ}\right)\end{array}\right.$ Outer curve form the outside track of cycloid track, by the cycloid equation $\left\{\begin{array}{c}y=d\mathrm{Cos}\left(\mathrm{N\θ}\right)+(R-r)\mathrm{Cos}\left(\mathrm{M\θ}\right)\\ x=d\mathrm{Sin}\left(\mathrm{N\θ}\right)+(R-r)\mathrm{Sin}\left(\mathrm{M\θ}\right)\end{array}\right.$ Inner curve form the inner orbit of cycloid track.As shown in Figure 2: 3 is basic circle among the figure, and 4 is the roller bearing of cycloid roller, and 5 is n=1, the cycloid track of m=2, and 6 is the cycloid roller, 7 is the roller of cycloid roller.The cycloid track is n=1, the cycloid track of m=2.Hereinafter to be referred as: the cycloid track is n=1, the form of m=2.

2, when

The time, by the cycloid equation $\left\{\begin{array}{c}y=d\mathrm{Cos}\left(\mathrm{N\θ}\right)+R\mathrm{Cos}\left(\mathrm{M\θ}\right)\\ x=d\mathrm{Sin}\left(\mathrm{N\θ}\right)+R\mathrm{Sin}\left(\mathrm{M\θ}\right)\end{array}\right.$ The outer curve of the curve that forms outwards squints, and offset distance is the roller radius r, forms the outside track of cycloid track; The inner curve of the curve that forms is to bias internal, and offset distance is the roller radius r, forms the inner orbit of cycloid track.When the curve that forms is the curve of a sealing, curve is outwards squinted, offset distance is the roller radius r, forms the outside track of cycloid track; To bias internal, offset distance is the roller radius r, forms the inner orbit of cycloid track.Work in-process can adopt with roller with the cutter of diameter along the cycloid equation $\left\{\begin{array}{c}y=d\mathrm{Cos}\left(\mathrm{N\θ}\right)+R\mathrm{Cos}\left(\mathrm{M\θ}\right)\\ x=d\mathrm{Sin}\left(\mathrm{N\θ}\right)+R\mathrm{Sin}\left(\mathrm{M\θ}\right)\end{array}\right.$ Track obtain.As shown in Figure 3: 8 is basic circle among the figure, and 9 is the roller bearing of cycloid roller, and 10 is n=2, the cycloid track of m=1, and 11 is the cycloid roller, and 12 is the roller of cycloid roller, and 13 is n=2, the curve that the equation of m=1 forms.

Two, the cycloid roller mainly is made up of the roller and the roller bearing of cycloid roller.1, the distribution of roller and quantity must satisfy the requirement of self rotation period in the cycloid roller.As shown in Figure 2: the cycloid track is n=1, the form of m=2.Be that the cycloid roller turns around along cycloid track public affairs, around self roller bearing axle center rotation 1/2 circle.Therefore, a roller can only accomplish for 1/2 rotation period, thereby a cycloid roller must have two rollers, and distributed by the rotation period, made it alternate rotation, accomplished the rotation complete period.2, when the cycloid equation that forms the cycloid track $\left\{\begin{array}{c}y=d\mathrm{Cos}\left(\mathrm{N\θ}\right)+R\mathrm{Cos}\left(\mathrm{M\θ}\right)\\ x=d\mathrm{Sin}\left(\mathrm{N\θ}\right)+R\mathrm{Sin}\left(\mathrm{M\θ}\right)\end{array}\right.$ When the curve that forms was the curve of a sealing, the cycloid roller only needed a roller to get final product.As shown in Figure 3, the cycloid track is n=2, the form of m=1.Be that the cycloid roller turns around along cycloid track public affairs, around self roller bearing axle center from taking two turns.Therefore, roller of cycloid roller can be accomplished two rotation complete periods, thereby, only need a roller to get final product.

Three, drive method, as shown in Figure 2, the cycloid track is n=1, the form of m=2.When the cycloid track does not change, for just, cycloid roller every public affairs counterclockwise in the cycloid track turn around with counterclockwise, promptly enclose around self roller bearing axle center rotation 1/2 counterclockwise; When does not change in the roller bearing axle center of cycloid roller, for just, the cycloid track whenever rotates counterclockwise a circle with counterclockwise, and the cycloid roller promptly encloses around self roller bearing axle center rotation 1/2 counterclockwise.Thereby the rotation rotating speed of cycloid roller can obtain by following relation.That is:

N wherein _GZBe the rotation rotating speed of cycloid roller, N _XBe the revolution rotating speed of cycloid roller, N ₁Rotating speed for the cycloid track.For the transmission of cycloid roller, there is following relation: promptly:

Work as N _X=N ₁The time, at this moment, the every public affairs of cycloid roller turn around promptly from turning around.Being equivalent to the cycloid roller does not produce relative rotation in the cycloid track.When the cycloid track of cycloid roller transmission is during only by the inner orbit of the outside track of cycloid track or cycloid track, can obtain more compact structure.The mark of this cycloid roller Gear Planet Transmission in transmission principle figure is as shown in Figure 4: 14 is the cycloid track among the figure, and 15 is the roller bearing of cycloid roller, and 16 is the cycloid roller, and 17 is the roller of cycloid roller.

Because the cycloid track is to utilize the cycloid equation $\left\{\begin{array}{c}y=d\mathrm{Cos}\left(\mathrm{N\θ}\right)+R\mathrm{Cos}\left(\mathrm{M\θ}\right)\\ x=d\mathrm{Sin}\left(\mathrm{N\θ}\right)+R\mathrm{Sin}\left(\mathrm{M\θ}\right)\end{array}\right.$ Form, thereby, as long as change Base radius R; Just can change the size of cycloid track, and its drive characteristic is constant, thereby; This cycloid roller Gear Planet Transmission with respect to the planetary pinion transmission, can make structural configuration that form is more flexibly arranged when combining with Gear Planet Transmission; The structural type restriction of mechanism is few, thereby obtains compact structure; And the cycloid track is therefore simple in structure, easy to process as long as adopt digital control processing to realize; When the roller in the cycloid roller was the wheeled construction that can roll or ball formula structure, the cycloid roller was done rolling friction in the cycloid track, thereby, higher transmission efficiency can be arranged.
