The wave spring causes and operation method for bearing preload

The wave spring is used for bearing preload, 2021 - the cause and the operating method 01 - 23 the following articles from the smiley waveform spring and retaining ring, the authors Smalley in not fasten your safety belt when we dare not to drive, as we are not using Smalley should not take when single wave spring bearing preload. Let us first to get to know some basic knowledge about bearing preload. What we call 'preload is what mean? Bearing can freedom of movement, and has many moving parts, these parts can coordinate as a whole. Occurring in the process of manufacturing and assembly tolerance stack is easy to cause some problems. This time we need for bearing preload, its purpose is to provide constant axial load bearing. So how do we proceed with bearing preload? If there are different types of operation method? We can through the two main methods for bearing preload. The first method is fixed preload, that is, using a locking mechanism to the inner ring and outer ring fixed in the appropriate position in order to realize the preload. Spring preload is a more common, simple and economic method, the method USES spring applied constant axial load in the side of the bearing in order to realize the preload. Smalley single wave spring can provide necessary in bearing between the inner and outer ring of pre-tightening force, at the same time compensate for all the tolerance stack or thermal deviation. This method can effectively reduce the axial and radial clearance, as shown in the figure below. Why do we have to bearing preload to help reduce clearance? Control clearance for maintaining functional and bearing life is necessary. For bearing preload can make different kinds of bearings, Ball bearing, needle bearing, etc. ) Keep constant contact with bearing ring. Provided by the spring of the continuous load can not only eliminate the radial clearance and axial clearance, still can bring other advantages. The overall goal of the preload is extend bearing life, thus achieve the goal of extend the life of the application. Spring preload the advantages of the appropriate bearing preload can prolong the life of bearing. For high precision and high speed application, you must use the preload spring; Such preload can avoid bearing facing more strict tolerance requirements, at the same time make it able to withstand higher running speed. The following is the advantage of spring preload summary: advantage can control the axial and radial clearance ball overall can cooperate with reliable bearing ring, and can withstand the size changes. Bearing wear small waveform design can increase the divide between the bearing load. Vibration noise reduction components noise is small, even in high vibration applications. Eliminate the phenomenon of ball skidded through ShiJiaHeng force make the movement more smoothly. Achieve precise localization of axis of wave spring can keep the center axis, and to achieve the best distribution of centrifugal. How do I determine which type of wave spring preload? Each of these applications are unique, this means that choosing the appropriate wave spring is crucial. Total tolerance is an important factor, because too much on bearing preload will reduce its service life, and in a high vibration system, preload starts to lead to higher output noise. Smalley bearing preload wave spring SSB series designed specifically for this application. We offer two kinds of single wave spring type respectively gap wave spring and take back wave spring. Gap type wave at the end of the spring is separated, and take back at the end of the wave spring is overlapping. To compress wave spring, after the end of the two kinds of configuration can be free to move along the circumference, it is superior to the traditional wave washer. If the wave washer excessive into spring chamber, the gasket may get stuck tight or harden, which leads to the spring load become unpredictable. We can provide more than 300 kinds of standard parts made of carbon steel and stainless steel, common bearing size to match. Please check the size of the bearing parameter table to make sure you need. If your application requires greater elasticity, can consider to we provide another layer of spring, it can satisfy the requirement of the higher preload.
