The invention is directed to an alignment assembly for changing the relative position of a plate of a pedestal assembly with respect to a processing chamber of a reactor. The alignment assembly is connected at a first end to a riser shaft of the heating assembly and at a second end to a drive shaft. One or more portions of the alignment assembly may be selectively axially rotated or laterally moved change the relative position of the plate with respect to the processing chamber as desired.

A steering system for a vehicle is provided. The steering system has a handlebar assembly and a steering column assembly connected to the handlebar assembly. The handlebar assembly includes a first conical surface and a first angular position limiter. The steering column assembly includes a second conical surface mated with the first conical surface, and a second angular position limiter configured to engage the first angular position limiter to limit an angular position of the handlebar assembly relative to the steering column assembly about a steering axis of the steering system. A compression element engages the handlebar assembly and the steering column assembly to compress the first and second conical surfaces against one another in order to fix the handlebar assembly to the steering column assembly. A plurality of linkages is configured to operatively connect the steering column assembly to at least one ground-engaging member of the vehicle.

A mechanical joint for transferring rotational motion between shafts at an angle and related assemblies. The assemblies can include both fixed and adjustable-angle joint housings for providing high torques in hard to reach areas. Other assemblies include improvements in inboard marine drives that correct the prop angle to generally align with the direction of travel of the boat and outboard marine drives with improved drive trains.

Embodiments are directed to a drive shaft apparatus comprising a first rotary member and a second rotary member arranged coaxially with said first rotary member. The rotary members are fixedly connected at a first end so that they rotate together. Each rotary member has a set of elements spaced apart around its circumference at a second end. The elements on the first rotary member are spaced apart from the elements on the second rotary member at rest. The first rotary member undergoes torsion when a load is applied during rotation, which causes the first rotary member elements to move closer to the second rotary member elements. The first elements engage the second elements when a torque load less than a yield torque is applied to the first rotary member, which transfers at least a portion of the torque load to the second rotary member.

An electric motor for an electric camshaft phaser, including: a housing; a nut fixed with respect to the housing and including a first plurality of threads; a drive shaft including a second plurality of threads, a portion of which is meshed with the first plurality of threads, and including a first segment; a rotor rotationally fixed to the drive shaft, and radially surrounding the drive shaft; a stator radially surrounding the rotor, and arranged to be energized to rotate the rotor and the drive shaft; and a first blocking element. The drive shaft is rotatable with respect to the nut, and the first segment is arranged to connect to the electric camshaft phaser to rotate an output gear of the electric camshaft phaser. A rotation of the drive shaft, in a first circumferential direction, is blocked by a contact of the first blocking element with the nut.

A modular motor assembly structure is disclosed and configured to couple with a drive shaft of an application device. The drive shaft includes a receiving slot. The modular motor assembly includes a main body and a combination key. The main body includes a shaft hole and a key groove. The shaft hole includes an opening and a central axis. The key groove is disposed on a side wall around the shaft hole and parallel to a central axis of the shaft hole. The combination key has a front end and a rear end. When one end of the drive shaft is inserted into the shaft hole along the central axis of the shaft hole, the combination key is at least partially accommodated in the receiving slot, and the front end faces the key groove. The combination key has a continuously increasing thickness from the front end to the rear end.
