How Does the Spindle Assembly Work?
The spindle assembly is the mechanical piece of the screw drive which turns in the opposite direction of the shaft. Screw drives are known to be the most common mechanism that powers any type of automobile. The screw is driven by two sets of screws in the case of a flat bed. In addition, there are two sets of cams in case of a cam drive and the cams rotate in the same direction. The spindle assembly is the piece of the drive assembly that holds the cams in place.
The speed of the screw drive assembly, known as rotation speed, is measured in RPM. RPM is commonly determined by using a mechanical probe that is attached to the shaft assembly. RPM is used to determine the rotational speed of the assembly as well as its torque.
The size of the spindle assembly is typically determined by the size of the engine of the vehicle that it will be used on. If the engine is small, the spindle assembly may be smaller and the shaft assembly larger. If the engine is large, the spindle assembly may be larger and the shaft assembly may be smaller.
When a screw drive assembly is designed for the job of a cam drive, the spindle assembly is made with the purpose of holding the cams in place. As with the cam drive, the screw drive assembly consists of two groups of screw and a cam to hold the cams in place.
Some types of screw drives require that a spindle assembly is manufactured prior to the installation of the drive. However, if the drive is a universal design, then the spindle assembly can be purchased after the drive has been installed. The spindle assembly that is necessary to hold the cams in place when a screw drive is used is called the cam block. It is a very thin piece of metal that holds the cam in position. It is typically constructed from either aluminum or steel.
A motorized spindle assembly consists of three main parts, which are the cam block, spindle assembly, and the control rod which connects the spindle assembly to the motor. The control rod is a spring type which moves to allow the cam to turn. The control rod also controls the speed and rotation speed of the spindle assembly. The cam block is a metal structure that holds the cam in place. The spindle assembly is installed in a hole drilled into the drive.
