Abstract
The utility model relates to a curling device of a drawn cup needle roller bearing. The curling device of the drawn cup needle roller bearing comprises a support and a support shaft, wherein two protruding shoulders are symmetrically arranged on the support, installation holes are formed in the protruding shoulders, and the two ends of the support shaft are respectively installed in the installation holes of the protruding shoulders. The curling device of the drawn cup needle roller bearing is characterized in that two roller wheels are installed in the position, between the two protruding shoulders, on the support shaft, the two roller wheels are both provided with a rolling flange edge, and a separation bush or a first surface bearing is arranged between the two roller wheels and enables the two roller wheels to maintain a matched space from the drawn cup needle roller bearing. The curling device of the drawn cup needle roller bearing is simple in structure and easy to machine. Because the bearing with the two roller wheels is adopted, the two sides of the bearing are stressed in the meantime, the stress is evener, the structure is reliable, and the design is favorable for stable quality of products and effectively avoids scrapping of the products.
Description
Technical field
The utility model relates to the Production of bearing equipment technical field, especially a kind of hemming device of drawn cup needle roller bearing.
Background technology
Drawn cup needle roller bearing is the needle bearing of slim punch forming outer ring, and its main feature is that depth of section is very low and to bear load-bearing capacity higher.An end face of bilateral open type drawn cup needle roller bearing is the bottom surface, and another side is bead face.The production technology of existing drawn cup needle roller bearing be the bottom surface down, then the roller of then packing into is carrying out crimping to another side, existing flanging process is to need roll extrusion on the bead face by a pinch roller in the outer ring, rely on roll extrusion power, make the outer ring inwardly curling, until moulding.Bearing outer ring is monolateral stressed, easily run-off the straight in rolling process, and bearing outside diameter size swell causes the roll extrusion of product to scrap.
The utility model content
The technical problems to be solved in the utility model is: overcome in the rolling process of prior art middle (center) bearing outer ring monolateral stressed, cause bearing to tilt, the technical problem that causes the roll extrusion of product to scrap, a kind of hemming device of drawn cup needle roller bearing is provided, realize that bilateral symmetry is stressed in the bearing outer ring rolling process, shaft strength is even, and the clamping external diameter, improve the quality of products, improve yield rate.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hemming device of drawn cup needle roller bearing, comprise support and back shaft, the convex shoulder that has two symmetrical settings on the support, has installing hole on the described convex shoulder, install respectively in the installing hole of convex shoulder at the two ends of back shaft, it is characterized in that: the position on the described back shaft between two convex shoulders is equipped with two rollers, all have the roll extrusion flange on described two rollers, be provided with between two rollers to make and keep between two rollers and drawn cup needle roller bearing be complementary spacer or first plane bearing of spacing.
For preventing between roller and the convex shoulder because contacting and wear and tear, be separately installed with the second plane bearing and the 3rd plane bearing between described two rollers and the mutually close convex shoulder.
Further, smooth and easy for roller is rolled, improve service life, described roller inner ring is installed on the back shaft by angular contact ball bearing.
A kind of embodiment, for ease of installing, described back shaft comprises cap body, polished rod and threaded rod, cap body and threaded rod lay respectively at the two ends of polished rod, the nut that is threaded and matches on the described threaded rod.
Another kind of embodiment, for ease of installing, described back shaft comprises polished rod section, the two ends of polished rod section have respectively the threaded portion, the clamp nut that described threaded portion is threaded respectively and matches.
The beneficial effects of the utility model are, the hemming device of drawn cup needle roller bearing of the present utility model is simple in structure, be easy to make, adopting two roller bearings is that both sides are simultaneously stressed, stressed more even, reliable in structure prevents the bearing outside diameter swell, be conducive to constant product quality, effectively avoid product rejection.
