Ball screw pair is to convert rotary motion to linear motion, or convert linear motion into rotary motion of the ideal product.Ball screw pair by screw, nut, reverse gear and ball bearing, ball screw pair is the function of rotary motion into linear motion, or convert torque into axial force repeatedly, at the same time combines the characteristics of high accuracy, reversibility and high efficiency. Ball screw pair with high accuracy, reversibility and high efficiency etc., this is the further extension and development of the trapezoidal screw, the significance of the development is the trapezoidal screw sliding action into a rolling action.
At the same time, the oil film also has a certain vibration absorbing ability.Add the lubricating oil, however, one of the biggest disadvantage is need good sealing performance, otherwise it will leak, and some have special requirements equipment lubricating oil leakage is not permitted, so people with other lubrication material to replace the lubricating oil, the invention bearing without oil, make it not only possesses the advantages of containing oil bearing, at the same time to eliminate the environmental pollution caused by leakage.
According to the material, Waxing Bearing’s products are divided into several categories, and roller bearing is one of them.Waxing Bearing carries out strict quality monitoring and cost control on each production link of roller bearing, from raw material purchase, production and processing and finished product delivery to packaging and transportation. This effectively ensures the product has better quality and more favorable price than other products in the industry. See more information on https://www.wxingbearing.com/.
Needle bearing with fine and long roller,so the radial structure is compact,its diameter and load capacity at the same time,with other types of bearing outside diameter to a minimum,especially suitable for the limited size of the radial installation supporting results. Needle roller bearing capacity big,applicable to the limited size of installation supporting structure,the journal as rolling surface hardening on the surface,bearing force fit in a hole,not for axial positioning.Needle roller bearing according to the use of different occasions,the machining accuracy and surface quality should be combined with bearing ring,use.Needle roller bearing is a centripetal needle bearing and thrust bearing parts of the bearing unit.
This is definitely a challenge for the machinery industry. However, this challenge was solved in the early 1960s. The British experts in related fields successfully developed oil-free bearings, that is, self-lubricating bearings, which perfectly solved the problem of bearing oil leakage. And self-lubricating bearings were successfully put into high-end machinery manufacturing fields such as aerospace in the late 1960s. Since its development, self-lubricating bearings have become an indispensable existence in many high-end fields.
Bearing ring (especially the outer ring) under alternating load and impact load, the stress it bears constantly exceeds the fatigue strength limit of the material, leading to the fatigue crack, and the crack eventually expands to a certain extent, leading to the fracture at the maximum stress of the parts.Generally occurs in the bearing area of the outer ring of the bearing, because the outer ring usually fits with the bearing box hole for clearance, and the bearing box body is a variable and elliptical part, which is easy to cause fatigue fracture under alternating load and impact load. Similar to fatigue fracture, when the stress on the bearing is greater than the tensile strength of the material, the inner ring cracks, usually due to improper installation, such as bearing installation tilt, resulting in partial load of the bearing, resulting in partial overload of the bearing caused by fracture;In addition, improper striking during installation caused bearing cracking and falling blocks, which is also classified as overload cracking.Most common interference when installation, and bearing fit size can also lead to large amount of interference of bearing ring crack (mainly has four row cylindrical bearing inner ring interference fit), interference is too big lead to inner ring stress is larger, especially thin cross section thickness (thickness of section < 12 mm) of inner ring, too much interference often leads to inner ring axial crack.
