04 14:28:12 click: 51 bearing has irreplaceable effect on machine tool movement, because it is in the meantime have a rolling effect, make the main shaft is a big development space.
Mechanical high speed, high -
Reducing speed requirements, making increased needle roller bearing load are not fixed.
In order to ensure that the requirements of high-speed operation, generally can choose general needle roller bearings, but, choose high precision ZSHST needle bearing bar will be provoked load talent shortage, lack of rigidity.
Hyster development by high-speed bearing no noise, low noise, vibration resistance characteristics.
This leads to a needle roller bearing become mechanical spindle unique choice.
So needle roller bearing on the other hand, also reduced the mechanical rolling load, everyone knows that the vibration of the mechanical rolling rolling overshoot will decrease the mechanical spindle become old, yea, so useful control of mechanical vibration of ups and downs,'s going to be a great help for machinery, precision needle roller bearing and plays a very important role here.
In order to satisfied with industrialization process to the high requirement of the machinery, hyster bearing more and more chose high precision lathe, grinding machine, including raw materials, etc. , which makes the traditional hundreds of RPM and fast speed up to ten times or even dozens of times.
Is a big promotion in the efficiency.
The selection of high precision needle roller bearing raised machine productivity, become old, yea, can continuous operation.
A kill two birds with one stone.
From roughness, roundness, the touch of appearance, the first exposure in the local appearance must occur crack depth of a crack, and along the direction of appearance point of view, surely to depth, from after the touch surface appearance, and appearance, and eventually formed the corrosion, whether viewed from the outside, or from the surface of the crack, the two policy (
Parts carburizing, quenching heat treatment, and other appearance after if you have uneven hardness, arrangement, and the internal stress of non-uniform and other whammy, touch stress generally occurs from opposite underground cracks under the influence of outward appearance quality is poor, if the parts has a flaw,
Oxidation and decarburization)
Crack, conflict or smooth, from appearance, along with the continuously to the high quality of mechanical industry demand, improve the life quality, performance and reliability continuously pursue the policy of production enterprises.
Hyster bearing and authigenic strict with oneself, ZSHST bearing requirements, high precision, stable quality, has become in the future to carry out the primary direction.
The previous: the status quo and progress in the study of needle bearing performance next: what materials need to prepare in the production of bearing
