TL;DR: In this article, a correction arc bevel gear supporting an automobile differential mechanism, which comprises a planet gear and a half shaft gear engaged with each other by arc teeth, is presented.
Abstract: The invention discloses a correction arc bevel gear supporting an automobile differential mechanism, which comprises a planet gear and a half shaft gear engaged with each other by arc teeth. The arc tooth correction parameters of the planet gear and the half shaft gear are as follows: the helical angle is 10-100, the pressure angle is 22.50-250, and the addendum coefficient is 0-0.8. The arc teeth almost are flat, straight, short and low and are separated from moulds without barriers after precision forging by using the parameter correction design. The correction arc bevel gear is processed by using the precision forging forming technology so as to greatly shorten the manufacturing time, reduce the manufacturing cost, further promote supporting application of the automobile differential mechanism, and improve the transmission quality of the automobile differential mechanism.

TL;DR: In this paper, the first tooth of the start part of the die has a tooth flank whose pressure angle is substantially larger than the desired final pressure angle of the tooth formed in a blank.
Abstract: PURPOSE: To prevent formation of a seam on the tip face of tooth by progressively decreasing a pressure angle of the start part of die from the first tooth and making the pressure angle of the final tooth the same as the pressure angle of the desired formed tooth. CONSTITUTION: The first tooth of the start part of die 64 has a tooth flank whose pressure angle is substantially larger than the desired final pressure angle of the tooth formed in a blank. Continuing teeth 67, 68, 69 and 70 of the die which succeeds to the first tooth 66 progressively and gradually decrease in the pressure angle of each tooth until the tooth 71, at which the pressure angle becomes substantially the same as the desired final pressure angle. Thereby, the material of the blank rod is moved outwardly in the radial direction along both teeth flanks of the die teeth equally with each other and, at the same time, is moved equally with the center between each tooth of the die, too. Thus, any large hollow is not formed on the tip face of the tooth 74, 75 and any seam is not formed on the tip of the tooth flank of the formed tooth.

TL;DR: In this paper, a linear relationship between the open gap of spool and cam rotary angle was put forward to conveniently control the speed of hydraulic press whose distributor spools are driven by cam mechanism.
Abstract: In order to conveniently control the speed of hydraulic press whose distributor spools are driven by cam mechanism,a linear relationship between the open gap of spool and cam rotary angle was put forward.Based on this,a new right cam lifting curve was put forward.Its curve equation and pressure angle mathematic model were established.Based on the analysis of working characteristics of relative parameters of cam mechanism and the maximum pressure angle after lifting curve minimized,the cam lifting curve was designed.It was successfully applied in 300MN die forging hydraulic press.The practical application shows that the optimization result is very prominent.

TL;DR: In this article, a flywheel clutch is used to change the straight reciprocating movement to the continuous circular movement almost without loss during the transmitting movement, which solves the problem of great loss of the kinetic energy caused by the pressure angle during the process.
Abstract: The present invention discloses a device capable of changing straight reciprocating movement to continuous circular movement. Two sides of a reciprocating two-sided rack or two single-sided racks reciprocating in the opposite directions are respectively engaged with a first gear and a second gear. The first gear and the second gear are fixedly connected with a first flywheel clutch and a second flywheel clutch respectively through a first transmission shaft and a second transmission shaft. An edge gear of the first flywheel clutch and an edge gear of the second flywheel clutch are engaged with a mainshaft gear at the same time. The device solves the problems of great loss of the kinetic energy caused by the pressure angle during the process of changing the straight reciprocating movement to the continuous circular movement in the prior art, namely, the problem of 30% of power loss of the crankshaft. In addition, a transmission gear is used to be coaxial with the flywheel clutch, so that the manufacturing is more convenient, and the manufacturing cost is greatly lowered. The flywheel clutch is a non-wear high-strength flywheel, so as to change the straight reciprocating movement to the continuous circular movement almost without loss during the transmitting movement.
