A belt-driven linear module includes a tensioning assembly and a drive belt. The tensioning assembly includes a support shaft and a bearing. The support shaft is configured to be installed at a driven end of the linear module. The bearing includes an inner ring and an outer ring. The inner ring is positioned on the support shaft, and the outer ring is configured to be wrapped by the drive belt of the linear module so as to tension the drive belt of the linear module.

A connection rod coupling assembly includes a settable shape mounting second component having a lateral, primary axis and a bearing assembly including a bearing assembly body. The bearing assembly body includes a substantially cylindrical outer surface and a center axis. The bearing assembly body is coupled to the settable shape mounting second component in a non-aligned configuration. That is, the bearing assembly body center axis is offset from the settable shape mounting second component primary axis. Thus, the position of the bearing assembly body center axis is adjustable by repositioning the settable shape mounting second component relative to a settable shape mounting first component on a swing lever. The adjustment of the bearing assembly body, in turn, adjusts the range of the ram assembly and the ram assembly body.

In addition, the present invention relates to a combination rail that is adapted to be used for this chain drive in a suitable manner.

In one embodiment, a fluid delivery system includes a motor assembly and a fluid pump assembly. The fluid pump assembly is spaced apart from the motor assembly, and at least one of the motor assembly or the fluid pump assembly is movable to change a distance between the motor assembly and the fluid pump assembly. The fluid delivery system includes a flexible linkage that couples the motor assembly to the fluid pump assembly, and is configured to transfer motion from the motor assembly to the fluid pump assembly. Further, the fluid delivery system comprises a linkage tightening mechanism configured to generate a tightening force on the linkage by biasing at least one of the motor assembly or the fluid pump assembly in a direction that increases the distance between the motor assembly and the fluid pump assembly.

An auto-tensioner includes: a base having a cylindrical part; an arm; a pulley around which a belt is to be wound; a friction member sandwiched between an inner circumferential surface of a cylindrical part and the arm; and a coil spring pressing the friction member against the arm in the axial direction and rotationally biasing the arm in one direction with respect to the base, in which the friction member includes: an arcuate surface, a first locking part, locked to the arm, and inclined with respect to the radial direction so as to face the one direction side as the first locking part goes toward an outside in the radial direction, and a second locking part, and the friction member and the arm include a restricting unit which restricts the friction member from moving toward the one direction side with respect to the arm.

A number of variations may include a product including a tensioner for a vehicle engine chain comprising a piston housing body portion having a piston bore formed therein for slideably receiving a piston connected to a chain guide shoe, and a camshaft bearing support or a combustion engine cylinder block or an engine cylinder head, extending from the body portion.

A belt drive for a work machine is disclosed. The belt drive has a drive belt that is wound around an input pulley and an out put pulley. The input pulley is rotated by a motor, and when rotated, transfers rotational motion to the output pulley by the drive belt. A controller is in communication with an input speed sensor that measures the input pulley and an output speed sensor that measures the output pulley. The controller calculates an input speed from the measurement of the input pulley, and an output speed from the measurement of the output pulley. The controller also sends a damaged belt signal to an operator control of the work machine when the output speed is lower by a predetermined threshold than the input speed.

A drive mechanism includes a mount block extending along an axis and a plurality of electric motors supported by the mount block. The electric motors are arranged in series along the axis to define an initial electric motor, one or more intermediate electric motors, and a final electric motor. The drive mechanism also includes a gear mounted to each of the electric motors, and an output member driven by the gear mounted to the final electric motor to receive the combined rotational torque from the gears of the series of electric motors.

The provided is a tensioning adjusting mechanism for a drum, which includes a front plate, a rear plate, a base, a drum, a supporting seat, a motor frame, a motor, a tension spring and a synchronous belt. The base is connected between a bottom of the front plate and a bottom of the rear plate; the drum is rotatably connected between the front plate and the rear plate and located above the base; the supporting seat is disposed on the base, the motor disposed on the motor frame, and a drive shaft of the motor is connected with a synchronous belt wheel.
