Compressing device for self-locking holder-free cylindrical roller bearing

Abstract

The invention discloses a compressing device for a self-locking holder-free cylindrical roller bearing. The compressing device is high in automation degree and comprises a rack and a base arranged at the lower end of the rack. A V-shaped supporting block matched with an outer ring of the roller bearing is arranged on the base. A plurality of rollers are evenly arranged in the outer ring of the roller bearing. An air cylinder is arranged at the upper end of the rack. A press rod is arranged on a piston rod of the air cylinder. A press block is arranged at the lower end of the press rod. The press rod stretches into the outer ring of the roller bearing to be matched with the rollers. The compressing device has the beneficial effects that the last cylindrical roller in the cylindrical roller bearing can be embedded in the position among cylindrical rollers at a time to achieve the interference fit aim; the automation degree and production efficiency are high; the labor intensity of workers is lowered; stress is even, and the overall quality of the bearing is guaranteed.

Description

Technical field [0001] The invention relates to a bearing processing equipment, in particular to a cylindrical self-locking roller bearing without a cage pressing device. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of load during mechanical transmission. Existing bearings generally include deep groove ball bearings and cylindrical roller bearings sealed on both sides. Because of the difference between the rolling elements and rings of deep groove ball bearings There is point contact between them, so the load capacity is small, and it is often crushed and squeezed. It can only be applied to transmission parts with small load capacity. When encountering transmission parts with large load capacity, cylindrical roller bearings must be used instead. The rolling elements of cylindrical roller bearings are connected by cages. Due to the existence of cages, the number of cylindrical rollers is reduced. This kind of bearing cannot mee...

Problems solved by technology

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. Existing bearings generally include double-sided sealed deep groove ball bearings and cylindrical roller bearings. There is point contact between them, so the bearing capacity is small, and they are often crushed and squeezed. They can only be used for transmission parts with small load capacity. When encountering transmission parts with large load capacity, cylindrical roller bearings need to be used instead, while the existing The rolling elements of cylindrical roller bearings are connected by cages. Due to the existence of cages, the number of cylindrical rollers is reduced. This kind of bearings cannot meet the requirements of high bearing capacity. In view of this phenomenon, people in the actual production process The cage in the cylindrical roller bearing is cancelled, and multiple cylindrical rollers are embedded in the outer ring of the cylindrical roller bearing with an interference fit. At present, the last cylindrical roller is embedded in the multiple cylindrical rollers by manual beating. To achieve the purpose of interference fit, a bearing needs to be knocked many times to complete, the degree of automation is low, the labor intensity is high, and the uneven force of manual knocking can easily lead to bearing damage and affect the overall quality of the bearing.
