SYSTEMS AND METHODS FOR ASSEMBLIES OF GEARBOXES AND GEARMOTORS

Abstract

A gearmotor assembly comprises a stepper motor, a reduction gearbox, and a torque limiter. The stepper motor is configured to receive input power to selectively rotate a motor shaft around a motor axis. The reduction gearbox includes a reduction gear assembly, a motor shaft coupling configured to operatively couple the motor shaft and the reduction gear assembly, and a gearbox coupling operatively coupled to the reduction gear assembly and having a gearbox coupling shaft.The torque limiter is positioned to operationally engage the stepper motor, reduction gear assembly, and gearbox coupling when the relative net torque between the stepper motor, reduction gear assembly, and gearbox coupling is below a maximum torque, and to operationally disengage the stepper motor, reduction gear assembly, and gearbox coupling when the relative net torque is equal to or greater than the maximum torque.
