Description

Technical Field

[0001] This utility model belongs to the field of bearing assembly technology, specifically relating to a device for manual assembly of double-row full complement cylindrical roller bearings, used for assembling double-row full complement cylindrical roller bearings. Background Technology

[0002] Bearings, as fundamental and commonly used wear parts in the machinery industry, are produced in a wide variety of specifications and types, in large batches, and with a high rate of production repetition. Bearing assembly is one of the crucial processes affecting bearing product quality. Currently, the manual assembly of double-row full complement cylindrical roller bearings involves: placing a rubber band on the inner raceway of the bearing, inserting the rollers one by one into the rubber band, and finally, fitting a fitting sleeve and removing the rubber band to complete the assembly of one set of cylindrical rollers. This manual assembly method is labor-intensive and inefficient. Due to the continuous decrease in assembly personnel in recent years and the increasing demand for products, the existing manual assembly efficiency in workshops can no longer meet market demands. Utility Model Content

[0003] The purpose of this invention is to provide a device for the manual assembly of double-row full complement cylindrical roller bearings, which can improve the operator's work efficiency while reducing labor intensity.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A device for manually assembling a double-row full complement cylindrical roller bearing includes an assembly base supporting the inner ring of the bearing; the assembly base is a cylindrical structure; the assembly base is supported below the inner ring of the bearing; an assembly sleeve with clearance fit is fitted onto the assembly base; the upper end face of the assembly sleeve is provided with a distribution plate for distributing rollers; the roller distribution plate has multiple grooves evenly distributed along the circumference for placing rollers, and the number of grooves is the same as the number of rollers in the double-row full complement cylindrical roller bearing.

[0006] The roller feeder disc is fitted with the large flange of the bearing inner ring with a clearance.

[0007] This utility model relates to a device for the manual assembly of double-row full complement cylindrical roller bearings. By adopting the above-mentioned technical solution, the manual assembly of two sets of full complement cylindrical roller bearings can be realized, which solves the problems of high labor intensity, low production efficiency and easy tilting of rollers in the rubber bands that are currently used for assembly.

[0009] In the diagram: 1. Assembly base, 2. Roller distribution plate, 3. Bearing assembly sleeve, 4. Double row tapered roller bearing roller, 5. Bearing inner ring. Detailed Implementation

[0010] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

[0011] like Figure 1 As shown, a device for manually assembling a double-row full complement cylindrical roller bearing is provided. The assembly base 1 of the measuring device is used in conjunction with the double-row full complement cylindrical roller bearing assembly sleeve 3. The roller distribution plate 2 is placed on the end face of the bearing assembly sleeve 1. The cylindrical rollers are placed in the groove of the roller distribution plate 2, and then pushed into the raceway of the inner ring 5 of the double-row full complement tapered roller bearing using the thumb and forefinger. The roller distribution plate 2 and the double-row full complement cylindrical roller bearing assembly sleeve 3 are moved upward to complete the assembly of a single-row full complement cylindrical roller bearing. Then, the spacer 1, the elastic retaining ring, and the spacer 2 are assembled in sequence. At the same time, the roller distribution plate 2 and the double-row full complement cylindrical roller bearing assembly sleeve 3 are moved upward to assemble the second set of rollers. After assembly, the roller distribution plate 2 and the double-row full complement cylindrical roller bearing assembly sleeve 3 are moved to complete the assembly of the entire double-row full complement cylindrical roller bearing.

[0012] This invention can also be used for the manual assembly of single-row full complement cylindrical roller bearings.
