Adjustable clearance design features of rolling ball bearings

The design features:

(1) manufacturing easy: Thanks to the adjustable intermediate links, so that parts of the process can be greatly relaxed tolerance zone size, the rejection rate also will drop exponentially. While reducing the accuracy of machine tools, the machining accuracy of machine tools in the general precision bearings possible. The technical level of the workers may be appropriate to reduce, with a certain economic benefits.

Convenient (2) assembling: the outer ring made after the split, you can easily adjust the radial wind power bearing clearance to the desired value, without the use of packet assembly method that is able to achieve high accuracy. Mounted on the shaft is also very easy to adjust without attaching other devices, simplifying the whole structure.

(3) to improve the situation by force: the double rows of rolling elements can increase the carrying capacity and can withstand axial force.

(4) reduce the types of parts: the outer ring made after the split, make rolling body covered in the fairway, so the cage can be omitted. This while reducing process, improve the carrying capacity, can be said to serve multiple purposes. Power Station Valve

(5) maintenance and repair easy: when the bearing clearance due to wear and tear caused by the ultra-poor, just appropriate to reduce the thickness of the shims can be reduced clearance, to restore the original accuracy, correspondingly prolong bearing life. In addition, when only the individual components of non-normal damage, can also be used to replace the damaged parts of the method to fix the bearing, or even the entire old as new, after all, a good way of reckoning. Deficiencies at 1.2

(1) increasing the inner cutting on the outer circumference, an externally threaded step. And easy to produce because of the presence of the thread stress concentration, while the heat 1P processing becomes difficult.

The axial dimension (2) of the flanged ball bearing is relatively large, and due to the randomness of the thickness of the adjusting washers have a greater volatility.

(3) for an outer thickened, so that an increase in material consumption.

Adjustable Rolling clearance presented here has the novel, reasonable structure, easy assembly, easy maintenance. Especially after the bearing outer ring from monolithic to modular axially split, so adjust the bearing clearance problems solved, for reference colleagues. The design can also be an extension of the idea to broaden to other types of bearing designs. The design of the case of non-standard bearing designs. There are many issues still need to explore deeper, deficiencies must be resolved. Truly eager to get peer guidance and help.
