Design of Worm Gear Set (online interactive calculator)
the gear ratio of a worm set is not as per the ratio of the pitch diameters of the worm and the wheel, as in the case of Spur and Helical gears. Rather, the gear ratio of a worm set is calculated based on the number of teeth on the worm wheel and the number of starts (threads) on the worm pinion ……select the diameter of the worm gear (wheel) and the worm pinion as per the availability of manufacturing tools…….

Methods of Mounting Spherical Roller Bearings
Spherical Roller bearings (SRB) are the most widely used bearings from the specific application point of view, such as Fans, Crushers, vibrating screens, Motors, Generators, or Gearboxes, Conveyors, Flywheel, Mechanical press, Drive shaft clutch, carriage wheels, etc. (list may be longer). Interestingly, the old design of the Railway Carriage also had a spherical roller bearing

Gearbox: Selection Criteria, Types of Bearings, Lubrication and Performance Monitoring
There are many factors to consider in the selection process of the proper gear speed reducer. Unfortunately, it is not as simple as calculating speed, torque, horsepower, and output RPM. With the introduction of computerized engineering manuals, most gear reducer manufacturers have made it easy to make basic gearbox selections. The basic selection process is

Gearboxes: Detailed Explanation, Terminology and Selection Process
What is a Gearbox? A box or case containing gear sets has many different names: speed reducers, reduction gearboxes, gear speed reducers, and gearboxes. Gearboxes are devices for the transmission of movement (precisely torque and speed) between two shafts, those shafts can have axis parallel, perpendicular, or cross to each other. In industry, gearboxes are

Adjustment of Taper Roller Bearing in a Gear Box
This article specifies the procedure on how to adjust a set of TRBs (Taper Roller Bearings) for a gearbox during mounting. Generally, bearing fitters do this based on practical experience, however, this topic will be a guide for new people in the bearing mounting field or application engineers to understand in general. So one should

Bearings for Special Applications: Car and Railway Wheel
The wheel bearings of a moving vehicle (car, truck, Railway Locomotive will have a complex set of forces with varying load conditions. If the object is moving in a straight line then the load will be purely radial and if the object is taking a turn then a combination of Radial and Axial loads will
