What are the structural characteristics of bolted roller bearings? The contours of the bolted roller bearings converge slightly on the proximal surface. The result of calibrating the contact between the needle roller and the center of the raceway line can prevent the devastating edge stress of the bolted roller bearing. Bolted Roller Bearings Roller bearings have thick-walled tube outers that can be heat treated at high temperature and high nitrogen, and high-precision screening rollers are precisely guided by ribs on the outer side of high stiffness. According to the linear contact, the roller can easily and easily rotate on the raceway to carry the load. In order to better reduce the ground stress, the outer side of the support point roller adopts the inclined surface design scheme, and the bolt bearing has various specifications and models, such as single sealing ring and double sealing ring, no sealing ring and with sealing ring. The bolted roller bearing is equipped with thin and long rollers (the roller is 3 to 10 times the diameter, and the diameter is generally not more than 5 mm), so the axial layout is compact, and its inner diameter and bearing capacity are the same as other types of bolted bearings. same. Small diameter, especially suitable for bearings with relatively limited axial mounting specifications. Depending on the application, bearings without bores or needle and ball bearing components can be screened. At this time, the surface of the motor shaft and the surface of the shell hole paired with the bearing are immediately used as the inner and outer turning surfaces of the bearing to ensure the load working ability and performance during work. Its performance is the same as that of a ring bearing. The strength, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing throw ring. This type of bearing can only bear the axial load. If there are scratches, rust, wear, slag, gravel, dust and stains on the mounting surface of the bolt bearing and the surface of the mating parts, it is very likely that the bearing mounting position is inaccurate; the second is that the composition of such accessories is wear-resistant. The working surface of the material and very easily worn bolt bearings can compromise the quality of the device. Therefore, ordinary industrial equipment will develop and deal with the joint surface development of joint parts such as motor shaft, bearing box cover hole surface, shoulder inner rib surface and joint surface of joint parts such as bushing, sealing ring, bearing end cover, etc. to carry out manufacturing and processing carefully and carefully. . If there is a rust layer, it can be eliminated with a fine file and polished with a fine sand cloth. In addition, be sure to clean the surface of the bearing parts and accessories on the joint parts. The use of bolted bearings is often questionable: bearings are delicate parts and must be stopped with relative care. No matter how high-performance bearings are used, the predicted high-performance cannot be achieved, assuming mishandling. Common questions about the use of related bearings are as follows: Hold the bearing tightly and clear the surrounding environment. Even fine dust invisible to the human eye can risk bolted bearings. Therefore, you should always insist on clearing the surrounding environment to avoid dust intrusion into the bearing, please use it dignifiedly. In the whole process of use, the strong impact on the bearing will cause imprinting, which will cause safety hazards. In relatively stressful situations, cracks and splits are very likely, so be careful. The bolt bearing contains the inner hole, the inner hole and the outer side and the STO type of the needle roller support frame parts between the inner hole and the outer side and the supporting facilities between the two can be installed independently. Since RSTO and STO type support point rollers do not have ribs and inner hole flat washers, it is necessary to configure the shaft diameter precise guide, and the precise guide form has to undergo precision machining. The diameter of the support point roll is the same as that of the STO series.
