Abstract
The invention relates to a single-row cylindrical roller bearing roller rivet assembling tool for a slurry pump. The tool consists of a guide clamping fixture, three positioning pins, a guide pin and a cross chisel, wherein the guide clamping fixture is annular, positioning holes are distributed along the circumferential direction, and the number of the positioning holes is the same as that of the rollers; the positioning pins are uniformly distributed on the circumference of the guide clamping fixture. The guide pins strike the rivet to lower the rivet into the rivet hole of the retainer. The cross chisel creates a "cross" between the rivet and the cage, causing the rivet to expand and thereby interference fit with the cage. The tool provided by the invention is adopted for assembly, the assembly efficiency is improved, and the problems of partial riveting, unfitness in riveting and falling of rivets in the working operation of the bearing are solved.
Description
Technical Field
The invention belongs to the technical field of bearing assembly, and particularly relates to a single-row cylindrical roller bearing roller rivet assembly tool for a slurry pump.
Background
Two ends of each roller of the cylindrical roller bearing of the slurry pump are respectively provided with a rivet hole, the rivet is often riveted eccentrically in the assembly process of the old assembly method, the operation flexibility, the rotation precision and the installation precision of the bearing are influenced, and the assembly efficiency of the old assembly method is low.
Disclosure of Invention
The invention provides a single-row cylindrical roller bearing roller rivet assembling tool for a slurry pump, which aims to solve the problem that rivets are easy to deflect in the traditional assembling method.
The invention provides a single-row cylindrical roller bearing roller rivet assembling tool for a slurry pump, which is used for solving the technical problem and comprises a guide mould, three positioning pins, a guide pin and a cross chisel, wherein the guide mould is in a ring shape, positioning holes are distributed along the circumferential direction, and the number of the positioning holes is the same as that of the rollers; the positioning pins are uniformly distributed on the circumference of the guide clamping fixture.
The tool provided by the invention is adopted for assembly, the assembly efficiency is improved, and the problems of partial riveting, unfitness in riveting, falling of the rivet in the working operation of the bearing and poor rotation precision are solved.
Drawings
FIG. 1 is a schematic view of a guide tire according to the present invention.
Fig. 2 is a schematic view of the guide pin of the present invention.
FIG. 3 is a schematic view of a locating pin of the present invention.
Detailed Description
The invention is further described with reference to the following drawings and detailed description.
The invention provides a single-row cylindrical roller bearing roller rivet assembling tool for a slurry pump, which consists of a guide clamping fixture, three positioning pins, a guide pin and a cross chisel, wherein the guide clamping fixture is annular, positioning holes are distributed along the circumferential direction, the positioning holes correspond to rivet holes, and the number of the rivet holes is the same as that of rollers; the three positioning pins are uniformly distributed on the circumference of the guide mould so as to position the guide mould. Adjusting the clearance of the bearing, horizontally placing the bearing after fitting, and horizontally placing the guide tire on the retainer. At the moment, the retainer has the advantages that due to the three-point positioning principle of the three positioning pins, the position deviation cannot occur in the rivet installing process, and the rivet is riveted to be deviated.
The rivet is driven using the guide pin so as to be lowered into the rivet hole of the retainer.
The rivet and the retainer are not firmly matched, so that the cross chisel is used for forming a cross shape between the rivet and the end surface of the retainer to prevent the rivet from falling off, so that the rivet expands to be in interference fit with the retainer, and the rivet is prevented from falling off.
The tool provided by the invention is adopted for assembly, the assembly efficiency is improved, and the problems of partial riveting, unfitness in riveting and falling of rivets in the working operation of the bearing are solved.
Claims (1)
1. The single-row cylindrical roller bearing roller rivet assembling tool for the slurry pump is characterized by comprising a guide clamping fixture, three positioning pins, a guide pin and a cross chisel, wherein the guide clamping fixture is annular, positioning holes are distributed in the circumferential direction, and the number of the positioning holes is the same as that of rollers; the positioning pins are uniformly distributed on the circumference of the guide clamping fixture;
