Buyers Guide	Application

Crown Gear drives or the Crown Right Angle Gear drives are essentially spiral bevel gear drives. The features which make them popular in applications include compactness, reliability, good design and an inexpensive way to transfer of speed or power.

These drives are made of high quality materials, that ensures a long service life and minimum maintenance. The Crown Gear Drives are sealed to provide protection from outside contaminants, to stop internal gears getting out of alignment or jam up. This results in a smooth and quiet operation, often in harsh conditions. Both the models, the two and three-way Crown right angle gear drives transmit excellent power. An essential feature of Crown right angle gear drives is the hardened spiral bevel gears along with a non-magnetic shaft made of stainless steel. The shafts are also made available in a wide variety. This includes, squared, splined, shortened, stepped and extended.

Types of Crown Gear Drives
Crown right angle gear drives are found in various standard models. All the models are specifically designed for complying with a vast range of shaft speed and torque requirements. Some of the standard model include the Two way Crown Gear Drives and the Three way Crown Gear Drives. They are available in 1:1 and 2:1 speed ratios.

Buyers Guide to Crown Gear Drives
Before venturing on to buy a Crown Gear Drive the following hints might prove useful in taking the right decision.

• Input/Output Ratio. Most standard ratios are of two types 1:1 and 2:1. In some cases it is also possible in getting a 1:2 ratio.
  
  
• Need for modifications: If any modification of shaft and/or housings are needed, it is imperative to send a drawing to the factory beforehand describing the application.
  
  
• Selecting the appropriate model: It is very important to have the right model with the right keyways.
  
  
• Designating Input/Output shafts: It is important to know that shaft will not turn faster than 2000 RPM. If say shaft number 2 in case of 2:1 ratio models is chosen as the input shaft, it can turn maximum at 1000 RPM. However in case of 1:1 ratio models there is no difference. The choice of shaft will affect mounting.
  
  
• Ascertaining Torque capacity: Be sure the designated output shaft bears a greater Torque capacity as compared to the applications load.
  
  
• Selecting the drive Type: You can choose either the
