Lovejoy flexible couplings and fluid power products address critical operational issues facing today’s hydraulic users. We provide solutions that are resistant to corrosion, require no lubrication, lower maintenance and downtime, and reduce noise levels – all with the quality, value and customer service you expect from Lovejoy.

Overview

Hydraulic drives are composed of three main components; the driver, the coupling, and the hydraulic pump.   The coupling connects the driver to the pump and allows for misalignment and the reduction of vibration between the driver and the pump.  In most hydraulic installations another component is required to connect the driver housing to the pump housing, this allows for simplified installation of the pump and improved alignment of the driver and the pump.

There are two primary types drivers in hydraulic applications; electric which uses an electric motor to drive the pump, and internal combustion which uses either a diesel or gas engine to drive the pump.

Common Applications:

  • Presses
  • Shears
  • Assembling equipment
  • Injection molding
  • Shredder
  • Bailers
  • Skid loaders
  • Excavators
  • Fork lifts

Lovejoy Products for Electric Motor Applications

Lovejoy offers all the components you need to connect an electric motor to a hydraulic pump.  The typical configuration is an electric motor with a round shaft with keyway, and a hydraulic pump with a spline shaft.    Some of these applications involve a “C” mount on the motor which allows for easy connection with the pump by using a Lovejoy “bell housing” mount, this allows for simplified design and installation by doing away with the need for pump mounting plates, shimming and allowing for accurate shaft alignment.  Along with the couplings and bell housings, Lovejoy offers water oil cooler, and reservoirs.

Lovejoy Products for Internal Combustion (Diesel or Gas) Applications

Applications are comprised of an internal combustion engine (diesel or gas fueled), and a hydraulic pump.  These are connected either shaft to shaft, or flywheel to shaft, depending on the engine output.

On shaft to shaft applications all you need is a coupling to connect the engine and pump.

On flywheel to shaft you need a flywheel mounting plate, a coupling, and a pump mounting plate.  Lovejoy offers all the components that are required to connect your engine and pump together; including flywheel and pump mounting plates.

As the typical hydraulic pump has a spline shaft subjected to profile distortion and fretting corrosion, Lovejoy offers the “L-Loc”. Lovejoy’s “L-Loc” feature eliminates premature spline shaft maintenance or replacement, reduces stress on equipment components, allow for quick assembly and removal, maintains equipment efficiency, and reduces equipment noise.
