TL;DR: In this article, the empirical equations for contact stress and bending stress of face gear and pinion through stepwise regression by using single factor test and orthogonal test were established by comparing them with results obtained from FEA.
Abstract: As the stress of gears determines the reliability of transmission, the stress research of face gear drive has great significance from the perspective of both theory and practice. The finite element model of orthogonal spur face gear meshing is attained via root-top section lofting method. The geometry parameters (include modulus, teeth number of face gear, teeth number of pinion and pressure angle) and transmission parameter (nominal contact force) are considered in the stress modeling. This paper, respectively established the empirical equations for contact stress and bending stress of face gear and pinion through stepwise regression by using single factor test and orthogonal test. The empirical equations have been validated by comparing them with results obtained from FEA.

TL;DR: In this article, a procedure for minimizing the size of roller-follower disc cam mechanisms under the constraint of maximum pressure angle is presented, where the pressure angle constraint is realized through establishing the permissible region for the cam center.
Abstract: This paper presents a procedure for minimizing the size of roller-follower disc cam mechanisms under the constraint of maximum pressure angle. The pressure angle constraint is realized through establishing the permissible region for the cam centre. The problem of cam-size minimization is reduced to locate the cam centre at the intersection of boundary curves of the permissible region. Its implementation is illustrated through examples.

TL;DR: In this article, a bearing for an angularly contacting bump stop, the washers of which consist of stamped sheet metal and have a surrounding geometry, is defined such that, in every cutaway containing the geometrical axis of rotation of the bearing, the lower raceway forms a lower circle arc which defines a lower axial curvature center, the upper raceway formed by the upper and lower curvature centers being located on an angular geometry axis, the angles of obliquity of a value between 5° and 65°.
Abstract: A bearing for an angularly contacting bump stop, the washers of which consist of stamped sheet metal and have a surrounding geometry. The geometry of the bearing is such that, in every cutaway containing the geometrical axis of rotation of the bearing, the lower raceway forms a lower circle arc which defines a lower axial curvature center, the upper raceway forms an upper circle arc which defines an upper axial curvature center, the upper and lower curvature centers being located on an angular geometrical axis that forms with the geometrical axis of rotation an angle of obliquity of a value between 5° and 65°. Specifically, the lower circle arc has two ends defining an opening angle of a value greater than or equal to 80° and a tangent located in a lower plane perpendicular to the axis of rotation at a lower tangent point defining with the end of the nearest lower circle arc a portion of the lower circle arc having an opening angle greater than or equal to 10°.

TL;DR: In this article, an original method to determinate the efficiency of the gear mechanism is presented, which consists in the elimination of the friction modulus, and analyzes the influence of few parameters about the efficiency value.
Abstract: The paper presents an original method to determinate the efficiency of the gear. The originality of this method consist in the eliminated of the friction modulus. On analyze the influence of few parameters about the efficiency value. These parameters are: z1 - the number of tooth’s for the primary wheel of gear; z2 - the number of tooth’s for the secondary wheel of gear; α0 - the pressure angle normal on the divided circle; β - the inclination angle. With the relations of this presentment, on can synthesizing the gear mechanisms.

TL;DR: In this paper, a rectilinear tooth form with the minimum pressure angle and pitch at a location where a gear ratio is maximum and equipped with the maximum pressure angle at a position where the gear ratio was minimum is presented.
Abstract: PURPOSE:To smooth functioning while facilitating working, by making up this device by a rectilinear tooth form provided with the minimum pressure angle and pitch at a location where a gear ratio is maximum and equipped with the maximum pressure angle and pitch at a location where the gear ratio is minimum. CONSTITUTION:In a gear ratio pattern of a rack pinion type variable gear ratio system steering gear, a gear ratio is the minimum G1 and a pressure angle alpham of a central tooth 21 is maximum during the time when an angle of revolution thetap of a pinion is O or theta1, and the pressure angle successively decreases and becomes minimum in a tooth that the gear ratio is maximum until the gear ratio reaches the maximum G2 when the angle of revolution thetap of the pinion is theta2. Pitches also diminish with advance to an end from a pitch P1 of the central tooth 21 and are built up in the order of P1>P2>P3>P4. A tooth form is rectilinearly made up.
