Gearbox bearing selection
WebBearing selection represents a compromise among many factors including the nature of the application, performance requirements and cost. A useful bearing-selection chart, which summarizes the principal considerations involved, has been given by A.O. DeHart and is reproduced in Table 1. WebMiter gears are+a special type of bevel gear designed to operate as pairs being identical in num/+ber of teeth and pitch (1 to 1 ratio only). Other Boston stock bevel gear sets are+available with ratios from 1/1/2:1 to 6:1.All Boston standard stock bevels and miters are manufactured with a 20а pres/sure angle.
