Machine builders assembly time saved

Thomson RediMount saves design and assembly time for machine builders

Thomson has introduced an innovative system that enables its TRUE planetary gearheads to be connected to any manufacturer's drive motor in a fast, simple and reliable manner.

The RediMount system allows machine and component manufacturers to to select the optimum combination of gearheads and motors for each and every application. The modular system enables gearheads and the mounting system to be stocked separately, which considerably reduces the associated costs. All Thomson Micron gearheads use an identical RediMount system, which guarantees that components are always compatible.

In addition to the high degree of flexibility it brings, RediMount also helps machine designers by reducing motor installation time and avoiding installation errors such as misalignment. First, the system features a self-centering hub. This ensures absolute concentricity between the motor shaft and gearhead pinion shaft eliminating the possibility of excessive wear on components during operation. The reliable alignment of the motor, gearhead and shaft - shaft-to-shaft centering - described here is a truly unique innovation in the marketplace. Another integral feature of RediMount is the pre-assembled pinion which makes the time-consuming pinion positioning process that is required by conventional systems a thing of the past. This not only saves valuable time be saved during mounting, but also eliminates another frequent source of error resulting from motor mounting.

The mounting process is streamlined using the RediMount system. The motor and gearhead can be mounted in just a few simple steps: To start with, the supplied adapter sleeve is inserted into the terminal hub of the gearhead. The gearhead drive shaft's input gear (pinion) is then pushed onto the motor shaft with the clamping hub. The two screws from the terminal hub are then securely fastened through the mounting opening in the RediMount adapter flange. In the final step, the motor flange is tightly screwed to the gearhead housing with the supplied screws.

The advance also extends to linear motion. Thomson's linear drive units will benefit from the fact that all solutions are supplied with the RediMount system as standard so that any servomotor can be specified without incurring any additional expense. Because the RediMount adapter flange is precisely tailored to the dimensions of the provided motor, the length of the drive block will always remain unmodified - meaning that engineers are not faced with any problems associated with the mounting position during subsequent motor replacements.

"With Thomson RediMount, conventional analyses, fitting problems and specifications of the connection sizes between the linear unit and the required motor are a thing of the past", explains Anders Trygg, Product Manager for linear units at Thomson. "All the customer needs to do is specify the part number of the Thomson linear unit as well as the manufacturer and part number of the motor, which the end user intends to use. We take care of the adjustment to the associated motor attachment without increasing the lead times or prices of the respective design."
