Shaft collar coupling

for pumpmotorflange

Bellhousings are the mechanical elements used to connect an electric motor equipped with standard flange to a hydraulic pump, thus forming the pump/motor unit. The bellhousings of this range allow to establish a perfect assembly between electrical motors with standard flange up to 270 kW and the majority of the hydraulic pumps available on the world market. They are produced in alluminium alloy and can be divided into two categories: SINGLE PIECE BELLHOUSING made of a single piece COMPOSITE BELLHOUSING made of several components – base bellhousing + flange – base bellhousing + distance ring + flange Composite bellhousings are employed under the fol- lowing conditions: 1. The dimension "H1" of the base bellhousing is infe- rior to the summed length of motor and pump shafts plus spider. 2. The fixing points of the pump are not compatible with the fixing holes of the bellhousing. Necessary indications for the choice of the correct bellhousing 1. Power of the motor (tab. motors see pag. 21/29). 2. Dimensional data of the hydraulic pump.
