W Type Bushings

Type W bushings are available in different thread configurations. Oil-filled bushings are designed for vertical installation, while recessed bushings accommodate line lead connections inside the lower end. While recessed bushings reduce the reserve factor between coupling torque and bushing torque, they add cost. In addition to oil-filled bushings, you can also choose bushings without sight glass.
In terms of insulation, the W-sleeve consists of two layers. The innermost insulation system consists of concentric capacitors. The outermost layer consists of several layers and is used for electrical testing. Although this is a solid insulation system, it requires extensive metal fittings and flexible seals. Recommended for voltages of 26 kV or lower. The outermost layer consists of porcelain.

Installation

1. Make sure the bushing cone and interior of the driven product are clean and free of anti-seize lubricant.
2. Place the bushing into the sprocket or other part type that accepts bushings.
3. Loosely place the cap screws into the pull-up holes. The bushing remains loose to ensure a slip fit on the shaft.
4. Using the key on the shaft, slide the sprocket or other part type to the desired position on the shaft. Make sure the heads of the cap screws are accessible.
5. Align the sprockets or part types, alternately and incrementally tighten the screws until they are taut. Do not use extensions on the wrench handle, and do not allow sprockets or parts to be pulled out and contact the bushing flange. There should be a gap between the bushing flange and the sprocket at this point to ensure that the gap does not close.

Removal

1. Loosen and remove cap screws.
2. Insert the cap screws into the threaded removal holes.
3. Tighten the inserted screws until the sprocket or other part type is loose on the shaft.
4. Remove sprocket/part type from the shaft.

Features of Split Taper Bushings

Additional benefits ofsplit tapered bushingsinclude a quick release and clamping capabilities. They can also be used to change the pore size. Split bushings are a popular choice due to their low cost and ease of application. Whether you're looking for the split casing for your next or new project, U.S. Bronze Foundry & Machine are the experts. Our innovative machining and casting capabilities allow us to manufacture complex split bushings and sleeves for your application.

Some manufacturers even sell a shaft locking device that can be installed in the counterbore of the drive part. These locking devices expand externally and internally so they can secure shafts and drive components without the need for a keyway. Because they are non-keyed, they save machine builders money and space. Plus, they allow infinite adjustment of the time. However, these products are generally more expensive than standard tapered bushings.
