Processing, manufacturing, and machine drive systems require reliability and high performance. Providing this level of performance in a right-angle gearbox requires high precision gears as well as quality materials and construction.
Flexibility and quality make Zero-Max's Crown Gear Right Angle Gearboxes an excellent option for low or high-volume applications as well as those involving steep or varying planes. All units are precision machined, carefully inspected, and come pre-lubricated for a long, maintenance-free operating life. Zero-Max offers a full range of sizes, as well as IP65-Rated Crown Gear Drives, from stock.
High-Quality Right Angle Transmission Gearboxes
Crown Gear right-angle gearboxes from Zero-Max deliver a dependable and economical 90-degree transfer of rotation, speed, and power in an efficient compact design with quiet operation. Our right-angle gearboxes feature high-quality spiral bevel gears mounted to the input and output shafts, precision sealed bearings, stainless-steel shafts, versatile mounting, cast aluminum housings, and maintenance-free operation. In addition, the IP65-Rated Crown Drives feature shaft seals, nickel-plating on the housing, and H1 rated food-grade grease.
The curved teeth of the premium spiral bevel gears improve gear teeth contact for increased torque capacity and reduced vibration and noise at high speeds. An enclosed design with fully supported shafts provides smooth and quiet operation while ensuring that internal gears don’t get out of alignment or become contaminated by debris.
Crown Gear 90 Degree Gearbox Options
All Crown Gear right angle gearboxes are designed for maximum strength and heat dissipation. Crown Drives are available with shafts of 3/8, 1/2, 5/8, and 3/4 inch diameter in two-way (one output shaft) and three-way (2 output shafts) units with 1:1 and 2:1 ratios. Three-way units in 1:1 and 2:1 ratios are also available with 1-inch shafts. Three-way units with counter-rotating output shafts are also available. Additionally, we can accommodate unique and custom requirements.
Standard and IP65-Rated Miter Gearbox Speed Ratios
Standard and IP65-Rated miter gearboxes are available in 1:1 and 2:1 speed ratios with two-way ("L") or three-way ("T") versions. All Crown Right-Angle Gear Drives support speeds up to 2,000 RPM.
Standard: black anodized aluminum housing, non-magnetic stainless steel shafts
Differentiating Two-Way, Three-Way, and Counter Rotating Gearboxes
Crown Gear standard two- and three-way right angle gearboxes feature two or three shafts positioned to create a 90-degree transfer of power transmission. Right angle drives are ideal for applications with limited space and where the driven equipment needs to be in close proximity.
Standard counter-rotating gearboxes are designed with two output shafts that rotate in opposite directions simultaneously, creating an ideal counterbalance. Counter-rotating 90 degree gearboxes can be used for applications that require additional stability in mechanical drive systems or for offsetting vibrations.
How to Select Your Crown Gear Right Angle Gearbox
Following this process will help you select the appropriate right-angle transmission gearbox for your application.
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.
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.
Choose drive type. Use either a 2-way or 3-way configuration.
Choose style. Determine if a Standard Model or IP65 Ingress Protection / Nickel-Plated Model is desired.
Select the correct model number. Select the valid model number based on the above selections. Note: 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, 1-inch shaft models are available in 3-way type only.
Ensure that the designated output shaft has a torque capacity higher than your application's load. Be sure to apply the appropriate service factor.
If your application requires modification of shafts or housings, send a drawing and a description of the application to the factory.
When to Choose an IP65-Rated Gearbox
Our IP65-Rated right angle gearboxes are tested for IP 65 Ingress Protection against dirt and water jets. IP65 rated gearboxes feature nickle-plated aluminum housings and are permanently lubricated with food-grade grease for food-related applications or other applications requiring washdowns. Specific IP65-Rated Gearbox applications Include:
Food Processing Equipment
Ovens & Dryers
Packaging Equipment
Test Equipment
