A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

High efficiency, high output transmission

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

An exemplary modified tooth proportion gear cutter includes a gear cutter that has a plurality of cutting teeth, and each one of the cutting teeth has a pair of cutting edges configured to cut a gear in a blank orientation so as to provide the gear in a final orientation. The gear in its final orientation has an involute tooth profile including a plurality of cut teeth and a plurality of valleys therebetween. The cutting edges are configured to cut the gear in the blank orientation, such that the gear in the final orientation includes the involute tooth profile with an active profile section and an operating pitch diameter that is spaced apart from the active profile section.
