Processing equipment, manufacturing equipment, and machine drive systems require reliable, high-power performance. Providing this level of performance in a right-angle transmission gearbox requires high precision gears and quality materials and construction. 

High-Quality Right Angle Transmission Gearboxes

Crown Gear right-angle gearboxes from Zero-Max deliver dependable, economical transfer of speed and power in an efficient compact design with quiet operation. Our right-angle transmission gearboxes feature spiral bevel gears mounted to the input and output shafts positioned at 90-degree angles, allowing the gearbox to intersect with a plane or cross on two parallel planes.

The curved teeth of the premium spiral bevel gears improve contact and reduce vibration and noise at high speeds. A fully enclosed design provides maintenance-free operation while ensuring that internal gears can’t get out of alignment, jam up, or become contaminated by debris.

Standard and IP65-rated miter gearboxes are available in 1:1 and 2:1 speed ratios with two-way (one output shaft) or three-way (two output shafts) versions.

  • Standard: black anodized aluminum housing, non-magnetic stainless steel shafts
  • IP65-Rated: nickel-plated aluminum housing, non-magnetic stainless steel shafts, shaft seals, food-grade grease
Flexibility and enhanced traction make Crown Gear right-angle gearboxes an excellent option for high-volume applications and those involving steep or varying planes. All units are precision machined, carefully inspected, and come pre-lubricated for a long, maintenance-free operating life.

Advanced Quality Construction & High-Performance Features

Zero-Max has over 70 years of proven design performance in thousands of applications. Our Crown Gear miter gearboxes provide numerous features and benefits, some of which include:
  • Double sealed bearings that hold lubrication in and keep dirt out.
  • Precision hardened and ground ball bearings for smooth, quiet, long operating life.
  • Non-magnetic stainless steel shafts that are corrosion resistant and require minimal maintenance.
  • Lightweight aluminum alloy housing for maximum strength and heat dissipation. Nickel-Plated housing for corrosion resistance standard in IP65-Rated models.  
  • Pre-lubricated and maintenance-free operation.  Food-Grade grease standard in IP65-Rated models.

How to Select Your Right Angle Transmission Gearbox

Following this process will help you select the appropriate right-angle transmission gearbox for your application.
  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 on 2:1 units.
  2. Designate which shafts are to be input and output shafts. This step is crucial to determine 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. Choose drive type. Use either 2-way or 3-way configuration.
  4. Choose style. Determine if a Standard Model or IP65 Ingress Protection / Nickel-Plated Model is desired.
  5. Select the correct model number. Select the correct model number; note that units with 3/8 inch shafts have flats and units with 1/2, 5/8, 3/4 and 1 inch shafts have standard keyways. Also note that 1 inch shaft models are available in 3-way type only.
  6. Be certain that the designated output shaft has a torque capacity greater than your application's load. Be sure to apply the appropriate service factor.
  7. If your application requires modification of shafts and/or housings. Send a drawing and a description of the application to the factory.
