The similarities and differences between Yuwei's standard bearings and non-standard bearings?

Release time: 2017-11-02 10:12:53 Views: 905

Shanghai Yuwei Bearing Co., Ltd. first let you know the similarities and differences between standard bearings and non-standard bearings?

Standard bearings: First, the dimensions and codes of standard bearings are unified at home and abroad, and second: the bearings have relevant data references for design and regulation. At the same time, the bearings assembled from these three specified dimensions can achieve the maximum performance, such as the highest speed. Lowest noise, maximum load, longest life, etc.

Non-standard bearings: First, the most common is non-standard size (such as: the inner and outer rings of the extended and widened bearings protrude on both sides or protrude unilaterally). Second, the outer ring has U-shaped grooves and V-shaped grooves. Again, the bearings must High temperature and low temperature resistance.

A customer of Yuwei Hunan, whose product design size is: inner diameter 13 * outer diameter 20 * thickness 5, this model closest to the standard model is 6801ZZ, the size is similar to the standard 6801ZZ (12 * 21 * 5) Ratio, the inner diameter decreases by 1MM, the outer diameter decreases by 1MM, and the thickness remains unchanged.

Then compared with the performance of the bearing and the performance are as follows:

Yuwei data analysis is as follows

One: Why is the performance of non-standard bearings in all aspects close to or equal to standard bearings 6801ZZ? Because the inner and outer diameters of non-standard bearings are increased by the same proportion, and the engineers of Yuwei will refer to and continue to use the standards The design of 6801ZZ, the cage steel balls of non-standard bearings use the standard 6801ZZ,

Second: If the size of non-standard bearings does not change by a certain amount, and when colleagues in the technical department of the customer company want to achieve the predetermined effect when designing the bearing, at this time, they also ask the customer to provide the environment in which the bearing is used. This kind of predetermined effect, Yuwei bearing technology will give the best solution under the conditions given by the customer, combining design and cost. Otherwise, the three dimensions of the inner and outer ring thickness of the bearing are out, but the performance of the bearing Is far from enough,

Third: The non-standard bearing delivery problem lies in the inner and outer rings of the bearing, and even the cage steel ball dust cover does not have the current mold and inventory, so the mold development and design capabilities and the company's production capacity are directly affected. Lead time to bearing,

In these major problems, the customer of Yuwei has met the prepayment requirements in the common problems of bearings (speed and noise load), but the clearance, especially the axial clearance, although we are arranging the standard clearance 6-13u However, in actual applications, the axial clearance cannot meet the customer's product requirements. If our company does not have a certain reference specimen in the design of this bearing, and there is no more than 10 years of production experience, then the inner and outer rings have been processed. OK, it is no longer possible to change the design. (Note: The ratio of the radial clearance to the axial clearance of the bearing is 1:13)
