The principle of modified gear was applied to silent chain transmission, and tooth profile equation of the involute sprocket was derived, then method of processing gear using imaginary rack cutter solved modification coefficient of involute sprocket. When Center distance of silent chain drive changed smaller, processing method of sprocket modification coefficient and range of modification coefficient values were analysed. The method by changing the modification coefficient of involute sprocket solves the problem that the chain links are increased or decreased in the actual application to be unable to meet the requirements of specific center distance, thus improve transmission performance of silent chain.

The pin-rack gearing is a particular type of cycloidal gearing which transforms a rotation motion to a linear one. Comparing with rack and pinion gearing and hydraulic swing cylinder, the pin-rack gearing has a more compact structure, less mass and lower cost. Nevertheless, designers always worry about vibration, noise and low use life as pin-rack mechanism working caused by deficiency of design theory. The present research derived the pin-rack gearing tooth profile equation and studied the geometry relationship among design parameters. The results can help to improve the pin-rack gearing design.

AbstractA compound oscillatory roller reducer (CORR) with a first-stage gear transmission and a second-stage oscillatory roller transmission is presented. The transmission principle of oscillatory roller transmission is introduced, and the tooth profile equation of the inner gear is derived. The analytical model of mesh force considering the installation errors and manufacturing errors is proposed. Then, parametric studies considering different errors on the mesh force are conducted. Results show that the design parameters are significant factors for mesh force. The mesh force is reduced by 17% as the eccentricity of disk cam increases from 2.5 mm to 4 mm. When the radius of the movable roller increases from 7 mm to 20 mm, the mesh force decreases by 8%. As the radius of disk cam increases from 125 mm to 170 mm, the mesh force is decreased by 26.5%. For the impacts of errors, the mesh force has a noticeable fluctuation when these errors exist including the manufacturing error of disk cam, the installation error of disk cam and the manufacturing error of movable roller change. The prototype of the reducer is manufactured and preliminary run-in test proved the feasibility of the transmission principle.

According to APDL language of ANSYS, this paper establishes the ideal identity model of tooth profile and gear based on ideal tooth profile equation, and it gets the ideal gear profile in meshing period and change curve of maximum contact stress with position of gear meshing. The result indicates that the contract stress distribution of ideal gear profile presents certain regularity with meshing state of double gear.

Finally, this paper gets the curve of meshing stiffness changes with load. The result indicates that the effect of load on deviation and tooth profile and gear meshing is larger than that on idea tooth profile and stiffness of gear meshing.
