Premium Spiral Bevel Gearboxes

Crown Gear sets the standard for 1:1 and 2:1 spiral bevel gear drives. Every component is precision machined, inspected and then carefully assembled. These right angle gearboxes are quiet in operation due to the special care taken in manufacturing and assembly. In addition, our 90° miter gearboxes are compact, reliable spiral bevel gear drives that are precisely designed for a dependable, economical transfer of speed or power.


Advanced Quality Construction

Crown Gear’s two and three-way 90 degree bevel gearboxes transmit power with quiet, dependable spiral bevel gears. These premium miter speed reducers feature hardened spiral bevel gears and non-magnetic stainless steel shafts. Another beneficial quality of our 90 degree gearmotors is that they are compact and feature multiple mounting options. The fully enclosed design ensures that internal gears can’t get out of alignment, jam up or become contaminated by debris.
 

Additionally, the cast aluminum housing of our right angle gearboxes are designed for maximum strength and heat dissipation. The drives are available with shafts of 3/8, 1/2, 5/8 and 3/4 inch diameter in two and three-way units with both 1:1 and 2:1 ratios. Three-way units in 1:1 and 2:1 ratios are available with 1 inch shafts. We can quote several unique types of shafts, including:

  • Squared
  • Splined
  • Extended
  • Shortened
  • Stepped
 

Right Angle Gearbox Selection Process

There is a standard process that should be considered before selecting the bevel gearbox that is correct for your specific application. This process goes as follows:
  1. Determine your preferred input/output ratio – Standard ratios are 1:1 and 2:1. It is also possible to use a step-up ratio of 1:2 by using shaft #2 as the input shaft.
  2. Designate which shafts are to be the input and output shafts – This step is especially important in making sure that no shaft will turn faster than 2000 RPM. If shaft #2 in the 2:1 ratio models is selected as the input shaft, it can turn at a maximum of 1000 RPM. In the 1:1 ratio models it makes no difference. However, the choice in either case will affect your mounting.
  3. Designated output shaft - The designated output shaft must have a torque capacity greater than your application load.
  4. Choose drive type – Choose either a 2-way or 3-way configuration.
  5. Select the correct model number – Select the correct model number that corresponds with your chosen drive type.
  6. Modifications of shafts and housing – If modifications of the shafts and/or housings are required, then please send us a drawing and description of the application.
