Abstract

A drive transmission gear unit is constructed to make possible adjustments in the relative spacial relationship between the unit gear wheels and a load shaft. The adjustment in the relative relationship between the unit and the load shaft may be carried out without varying the engagement relationships of the rotary elements within the unit. A centering arrangement is provided in the unit whereby the gear housing portion is rotatable about a driven shaft, thus enabling the gear unit to adjust for slack developing in any belt or chain tension means used to transmit rotary motion to a load shaft.
