The bolted roller bearing is a precision mechanical component, and the fast and simple 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-row or double-row cylindrical rollers, and their full-complement structure can withstand heavier radial loads, but cannot withstand the movement of some heavy machine tools or heavy transmission equipment. Large tilting moments and bidirectional axial loads from misalignment, skew or short shocks. At the same time, limited by its own structure, it is difficult to achieve reliable sealing. Contents of the Invention The present invention provides a bolt-type sealed double-row full-complement angular touch ball roller bearing that can withstand large axial loads and overturning moments in view of the bidirectional axial load and tilting moment existing in the practical use of the bolted roller bearing. In order to achieve the above purpose, the present utility model adopts the following technical scheme: a bolted roller bearing, comprising an outer ring, a bolt body, a short inner ring and two rows of steel balls, characterized in that: the bolt body includes a head, a journal and a thread The head of the bolt body and the short inner ring are respectively provided with an inner ring channel. The short inner ring is sleeved on the journal of the bolt body and the narrow end face of the short inner ring is in contact with the narrow end face of the head of the bolt body. The short inner ring cooperates with the journal of the bolt body through interference. Ring channel, steel balls are filled between the inner and outer ring channels in two rows of full filling. During the operation of the high-pressure cleaning pump, the staff must stay on the site, not leave at will, and should not approach the moving parts of the equipment to avoid risks. When the equipment is running, it is not allowed to operate at will, and it is not allowed to directly touch the twisted surface of the equipment with hands. Even if you notice a perverted problem with your device, turn it off and wait for it to stop completely before proceeding. Before opening the device, look for any significant changes and take care to ensure proper lubrication. If the oil level is found to be too low or abnormal noise is heard, the equipment needs to be shut down for inspection and repair. Assuming that the temperature of the working environment is low, after turning on the high-pressure cleaning pump, run it for a period of time without any load, and then gradually speed up after the oil temperature rises. During operation, staff also need to pay special attention to the temperature of the bearing. Assuming that the bearing temperature is abnormal, it needs to be dealt with in time. The outer ring of the bolted roller bearing adopts the full complement cylindrical roller bearing with thick outer ring wall. It is widely used in various industries, such as machine tools, metallurgy and other industries. The outer ring of the construction roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has cylindrical and arc shapes, which can be designed to match the raceway surface according to the application site. With this outer ring, the rollers can rotate directly on the raceway and can withstand heavier loads and shock loads. The bearing is of sealed structure and filled with lubricating grease to provide long-term effective lubrication, and users can avoid lubrication. For harsh operating conditions, it can be designed to supplement the lubricating grease channel to improve the service life of the bearing. Improper purchase of the bolt roller bearing can also cause the roller bearing to heat up. After smoothing, it can reduce the wear of parts in motion, ensure the accuracy of the press, and reduce energy consumption. The main roller is the main bearing body in a set of composite rollers. It mainly accepts vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full complement roller bearing, it can also be used as a one-way bearing alone.
