- Tapered-bore, antifriction bearings are mounted either on adapter sleeves or on tapered shaft seats.
- In cases where tapered bore bearings are mounted directly on the shaft, the shaft must conform to the tapered bore of the bearing to assure proper fit. If a proper fit is not achieved, the results could be:
- Turning of the bearing inner race on the shaft.
- Uneven loading of the bearing.
- Severe inner race hoop stress.
- Insufficient support (back-up) of the inner race on the shaft.
- All of these conditions could lead to premature bearing damage. Therefore, the manufacture, maintenance and measurement of accurate shaft tapers is important.
- There are two accepted ways of measuring tapered shafts: ring gages and sine bar gages.
- Precision measurement of tapered shafts is difficult with ring gages and may be impossible in the case of large shafts where gages are large, cumbersome and heavy.
- Sine bar gages provide an accurate and easy method of measurement.
- Lightweight and easy to handle and learn, sine bar gages achieve precise gagging of the shaft size and taper.
- A complete set for measurement of 1:12 shaft tapers consists of 3 in, 4 in, 5 1/2 in, 7 in, 10 in and 14 in sine bar gages, sine bar saddle no. T-5491-C, web clamp no. T-5489-A and a wooden box no. T-5224-C. A complete set for 1:30 shaft tapers consists of 4 in, 6 in, 8 in and 12 in sine bar gages.
- Sine bars can be purchased individually, or in any combination of sizes to meet your individual needs.
- All sine bars require a sine bar saddle and web clamp. A wooden box is optional.
- For information on the use of sine bars, prices and delivery, consult your Timken representative.
