Abstract
The utility model provides an inner-ring-free needle roller bearing for a cross axle type rigid universal joint, which at least comprises an outer ring, a needle roller group and an oil seal. The roller bearing group is composed of roller bearings distributed in a ring shape, the needle roller group are installed inside the outer ring, contacted with the inner wall of the outer wall and capable of rotating on the inner wall of the outer ring, the oil seal is arranged on one side of the inner ring provided with an opening, the inner diameter of the outer ring ranges from 18.902 to 18. 929, the diameter of the roller bearing ranges from 2.095 to 2.098, and the inner diameter of the ring-shaped roller bearing group is 14.69mm. The inner-ring-free needle roller bearing for the cross axle type rigid universal joint is capable of recycling waste products in the outer ring manufactured in manufacture and processing of primary products, thereby saving resources.
Description
Technical field
The utility model relates to a kind of cross shaft rigid universal joint and uses needle roller bearing without inner ring, is specially a kind of needle bearing that does not have inner ring that is used on the cross shaft rigid universal joint.
Background technique
The existing needle roller bearing without inner ring that is used on the cross shaft rigid universal joint; The internal diameter of needle roller group is 14.69 millimeters; The diameter of axle with the matching used cross axle of needle bearing also is 14.69 millimeters simultaneously; The diameter of needle roller is 2.003～2.006 millimeters, and the internal diameter of outer ring is 18.718～18.745 millimeters, and this design meets the JB/T3232 standard-required.In the long-term production course of working; We find to exist some defectives: the id tolerance of outer ring is 0.027 millimeter; Because outer ring technology in machining is complicated; Especially to the processing of outer ring internal diameter, adopt traditional grinding to be difficult to reach tolerance, the substandard products that process are more.Also there are some manufacturers to adopt the automatic bearing internal grinder processing of numerical control at present; But still there are some substandard products; In these substandard products size less than 18.718 millimeters can carry out the secondary grinding; Size can only scrap greater than 18.745 millimeters product, has caused the waste of raw material and resource, has reduced the profit of enterprise.
Summary of the invention
The utility model provides a kind of cross shaft rigid universal joint to use needle roller bearing without inner ring, has solved shortcomings such as the existing in process of production material of original product and the wasting of resources.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of cross shaft rigid universal joint is used needle roller bearing without inner ring; At least comprise outer ring, needle roller group and oil sealing, the needle roller group is formed by being arranged in circular needle roller, and the needle roller group is installed in the outer ring; Contact with the inwall of outer ring and can on the inwall of outer ring, rotate; Oil sealing is installed on the side that opening is arranged on the inner ring, and the internal diameter of outer ring is 18.902～18.929 millimeters, and the diameter of needle roller is 2.095～2.098 millimeters; The internal diameter of circular needle roller group is 14.69 millimeters.
The internal diameter of outer ring is 18.916 millimeters; The diameter of needle roller is 2.097 millimeters.
A kind of cross shaft rigid universal joint that the utility model provides is used needle roller bearing without inner ring, and the internal diameter of needle roller group and existing product internal diameter are identical, can exchange with original product; The internal diameter that is about to inner ring suitably increases, and makes some oversize substandard products that in original product manufacturing process, produce to recycle, thereby has practiced thrift resource.
Description of drawings
The cross shaft rigid universal joint that Fig. 1 provides for the utility model is with the structural representation of needle roller bearing without inner ring;
Among the figure, 1-outer ring, 2-needle roller group, 3-needle roller, 4-oil sealing.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The cross shaft rigid universal joint that the utility model provides is as shown in Figure 1 with the structure of needle roller bearing without inner ring, is made up of outer ring 1, needle roller group 2 and oil sealing 4.Needle roller group 2 is installed in the outer ring 1; Contact and can on the inwall of outer ring 1, rotate with the inwall of outer ring 1; One side of outer ring 1 is an opening, and needle roller group 2 is installed in the outer ring 1 by opening, and the internal diameter of outer ring is 18.902～18.929 millimeters; Adopt 18.916 millimeters of best internal diameters in the present embodiment, the internal diameter of needle roller group 2 is 14.69 millimeters.Needle roller group 2 is formed by being arranged in circular needle roller 3, and the diameter of needle roller 3 is 2.095～2.098 millimeters, adopts 2.097 millimeters of optimum diameters in the present embodiment.Oil sealing 4 is installed on the opening of outer ring 1, prevents that flow of lubricant from going out the outer ring.
This cross shaft rigid universal joint is used needle roller bearing without inner ring, and therefore the internal diameter of outer ring can be recycled the scrap products in the outer ring that in the original product production and processing, makes greater than the internal diameter of outer ring in the original product; The internal diameter of needle roller group is identical with original product in this product simultaneously, is 14.69 millimeters, can exchange with original product fully and use.
