The overall design of the composition of the bolted roller bearing includes the shaft support point end structure, the mutual cooperation of the roller bearing and related parts; the gloss and airtightness of the roller bearing; and the rigidity of the application of the bearing system, etc., all of which must be done. Rules, otherwise the stamping die needle roller bearing will not be able to work normally. In addition, it is also effective to use the fixed method of needle roller bearings. Assuming the two sides are fixed, each bearing will bear the bearing force in one direction. At this time, a small amount of heat shrinkable film is allowed in the axial period. After the roller bearing is installed, the radial clearance should be 0.25mm-0.4mm, which can be adjusted according to the sealing ring or screw. However, this kind of immobilization method will limit the dual fitness movement of the needle bearing, so it is generally suitable for use on some shafts where the operating temperature change is not large. When using, the thermal elongation rate and the compensation clearance between the bearing cover and the center of the outer inner hole must be considered. The bolt roller bearing part consists of four parts: the main roller, the side roller, the shaft head and the back cover. Roller bearing The main roller bearing of the main roller is the main rotating bearing body in the roller bearing, which can bear the impact load and load in the vertical direction, and has a strong corrosion resistance (interpretation: refers to rot, decay, erosion, etc.) , wear resistance and impact resistance, the main roller is a full complement roller bearing, so it can also be used as a one-way bearing independently. The side roller of the roller shaft, the outer side of the roller bearing is a full complement cylindrical roller bearing with a thick outer side wall. The diameter surface of the roller is cylindrical and arc type, which can be designed according to the place of use to cooperate with the dovetail guide surface. With this type of outer side, the rollers can instantly roll over on the dovetail rails and can handle heavier and harsher loads. The side roller is the second preface of the bolt roller bearing manufacturer. It can bear the load of horizontal deflection. Like the main roller, the side roller also has strong corrosion resistance (interpretation: refers to rot, decay, erosion, etc. ), abrasion resistance and impact resistance. The design technique used in 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 placement. Roller bearing shaft head, which is a part of the connection between the roller bearing and the mechanical equipment. Under normal circumstances, the top of the shaft head is designed with rounded corners, which is very convenient to install. The back cover plate of the roller bearing fixes the side roller and the main roller in the same position. The unreasonable technique of the anchor bolt roller bearing can also cause the roller bearing to become hot. Based on lubrication, it can reduce the damage of the parts during 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 component of the roller bearing is very tight and fully develops their respective benefits. The anchor bolt roller bearing side roller is the second bearing in a set of composite rollers. The link bears the horizontal deflection 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 placement. We need to develop protection, maintenance and inspection of such parts under the condition of use, so that their service cycle time can be longer and longer.
