The Jensen Mixers Series 600 Gearbox is the model 6600.  The Model 6600 gearbox typifies the superior design engineering that has gone into every part of the Jensen Mixers Series 600 Mixer. Maximum gear loading is 54% of rated capacity. Bearings have been selected for extremely long life even in continuous, heavy duty service. The lower flexible coupling half provides rain and dirt protection for the upper pinion bearing. Internal air volume has been reduced to eliminate condensate problems in tropical and coastal areas. Gear case parts are of high strength, 356-T6 heat treated aluminum alloy. The body is of heat resistant steel to assure positive protection against product leakage under conditions of high temperature.

  • The gear box may be removed as a unit for shop maintenance without disturbing motor mount alignment or moving coupling halves.
  • Gear inspection is simplified by the cartridge type pinion assembly which may be removed easily and replaced without re-adjustment.
  • All moving parts are completely enclosed by protective covers.
  • Housing have rabbeted joints for positive alignment and are O-ring sealed.
  • Gear box housings form a protective enclosure around the mechanical seal, eliminating exposure to the elements and resulting in longer seal life.

Operating Oil Temperature

The gearbox operating oil temperature is impacted by several variables. The cause of the heat generation is associated with friction in the teeth of the gearset, in the gearbox bearings and in the mechanical seal faces. The heat build-up in the gearbox is impacted by the ambient air conditions of temperature and wind velocity which supply cooling to the case. The amount and type of oil in the gear case also impacts the heat build-up. Alignment of the motor and the cooling, or heating, provided by the motor fan also impacts the heat generation and loss. As a result there are differences in the gearbox oil temperatures between similar mixers operating in somewhat similar conditions. Therefore the following numbers act as a guide in understanding what can be expected from a mixer that is operating satisfactorily. There is also a breaking-in period for a new gearbox during which time the heat generated is higher.
