QUICK RELEASE AUTOMATIC TENSIONING MOTOR BASE AND SPRING COMPRESSION RETENTION MECHANISM

摘要

A quick-release automatic tensioning motor base for supporting a motor. The motor is operably coupled to a device to be driven via a drive belt. The motor base includes base brackets and at least one guide rail fixedly coupled between the base brackets. A platform assembly, which supports the motor, is slidably coupled to the guide rail. A spring assembly is selectively coupled between the base brackets and fixedly coupled to the platform assembly. The spring assembly applies a biasing force to the platform assembly to maintain a belt tension along the drive belt. A quick-release assembly selectively engages the spring assembly and base brackets to permit movement of the quick-release assembly between a fastened position and a released position. A spring compression retention assembly is operably coupled to the spring assembly to maintain spring compression on the spring assembly even when the quick-release assembly is in the released position.

1. A quick-release automatic tensioning motor base for supporting a motor relative to a fixed structure, the motor driving a device to be driven via a drive belt, the quick-release automatic tensioning motor base comprising:
at least two base brackets connectable to a fixed structure, at least one guide rail being fixedly coupled between the at least two base brackets; a platform assembly slidably coupled to the at least one guide rail for movement along the at least one guide rail relative to the at least two base brackets, the platform assembly being configured to support and retain the motor thereon; a spring assembly being selectively coupled between the at least two base brackets and fixedly coupled to the platform assembly for movement therewith, the spring assembly applying a biasing force to the platform assembly to automatically maintain a predetermined belt tension along the drive belt; a quick-release assembly having a quick-release member selectively engageable between the spring assembly and the at least two base brackets, the quick-release assembly being positionable in a first position to retain the spring assembly to at least one of the at least two base brackets and a second position to release the spring assembly from the at least two base brackets; and a spring compression retention assembly being operably coupled to the spring assembly, the spring compression retention assembly maintaining spring compression on the spring assembly even when the quick-release assembly is in the second position.
