The bolted roller bearing is a precision mechanical element, and the fast and easy installation of the bearing on the plane of the equipment rack can be realized through the bolt shaft. The rolling elements of existing bolt-type roller bearings are mostly needle rollers or single or double row cylindrical rollers. Large tilting moment and bidirectional axial load caused by misalignment, skew or short-term impact, and limited by its own structure, it is difficult to achieve reliable sealing. The bolt bearing is pushed up and down in a passive habit, and the application habit is: you don't have to actively turn, if something steps on it, he will move! The bolt bearing is generally passively driven. The bolt type curve roller is generally a full complement roller structure. The bolt shaft raceway position is heat treated. In order to prevent stress, the outer surface of the outer ring of the thick-walled tube of the roller is arc-shaped. The outer ring has two overall ribs, and the axial direction is correctly guided by the rollers. The top of the bolt shaft head and the riveted side flat washers provide axial support for the outer ring according to the rollers. Generally, it is passively driven, and the bolt type curve diagram The rollers are generally constructed of full complement rollers, and the position of the bolt shaft raceway has undergone heat treatment. In order to prevent stress, the outer surface of the outer ring of the thick-walled tube of the roller is arc-shaped. Correct guidance. The top of the bolt shaft head and the riveted side flat washer provide axial support for the outer ring according to the roller. The inner diameter of the bearing is the national standard, and the dimensional tolerance is strict. The diameter of the bolt bearing bolt is not the dimensional tolerance of the mutual mating surface. Too loose, if the bolt bearing is to use the external thread surface to cooperate with each other, the mutual cooperation is not easy to transmit a large rotational torque. Bolt bearing If you can find a suitable mutual matching specification bolt in a pile of bolts, the non-external thread surface mutual matching can of course be used. The roller bearing is mainly composed of four parts: the main roller, the side roller, the shaft head and the back cover. The main roller bearing of the main roller is the main rolling bearing body in the roller bearing, which can bear the impact load and load in the vertical direction, and has strong corrosion resistance (interpretation: refers to rotting, subsidence, corrosion, etc.), Wear resistance and impact resistance, the main roller is a full complement roller bearing, so it can also be used independently as a one-way bearing. The side roller of the roller shaft and the outer side of the roller bearing are full-complement cylindrical roller bearings with thick outer side walls. The diameter surface of the roller is cylindrical and arc-shaped, which can be matched with the dovetail guide surface according to the design scheme of the application site. With this type of outer side, the rollers can be flipped on dovetail rails instantly and can take heavier and shock loads. The side roller is the second medium of the roller bearing. It can bear the load in the horizontal direction. Like the main roller, the side roller also has strong corrosion resistance (interpretation: refers to rotting, subsidence, corrosion, etc.) , wear resistance and impact resistance. The design method selected for it is that there is no inner ring full of needle rollers, and a mandrel is used to replace the shaft head and the inner ring for butt installation. Roller bearing shaft head, which is part of the connection between the roller bearing and the mechanical equipment. Under normal circumstances, the design of the top of the shaft head is rounded, which is very convenient to install. The back cover of the roller bearing fixes the side roller and the main roller together. The unreasonable method of the anchor bolt roller bearing can also cause the roller bearing to become hot. According to the lubrication can reduce the damage of the parts in the fitness movement, ensure the precision of the press, and reduce the energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication, etc. Each constituent part of the roller bearing is very important and gives full play to their respective roles. The side roller of the anchor bolt roller bearing is the second bearing medium in a set of composite rollers, which mainly bears the horizontal load, and also has strong impact resistance, wear resistance and corrosion resistance. The side roller is a full needle roller design without inner ring, and a mandrel is used to replace the inner ring and the shaft head for butt installation. In the case of application, we need to carry out maintenance and repair of such parts, so that their application cycle time can be longer and longer.
