Right Angle Crown Gear Drives Standard and IP65-Rated

How The Crown Right Angle Gear Drive Works Crown two and three-way right angle gear drives transmit power with quiet, dependable spiral bevel gears. Crown right angle gear drives feature hardened spiral bevel gears and non-magnetic stainless steel shafts. 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. All Crown right angle units feature a cast aluminum housing designed for maximum strength and heat dissipation. The standard units feature a premium grade grease (-50°C...

Crown Gear Drives New IP65-Rated Crown Right Angle Gear Drives Zero-Max also offers a complete line of IP65-Rated Crown Drives for applications that need Ingress Protection and/ or Corrosion Resistance – such as food-related or other applications requiring frequent washdowns. The IP65-Rated Crown Drives feature a special housing and shaft seals for added environmental protection. They were tested at an independent laboratory to obtain the IP65-Rating for both dust and water jet protection. The Nickel-Plated Housing and non-magnetic stainless steel shafts also help to prevent corrosion in harsh...

How to Select Crown Gear Drives 1. D etermine 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. (See drawings on pages 3–4). 2. D esignate Which Shafts Are To Be Input And Output Shafts. This step is especially important 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...
