Abstract
The utility model discloses the withstand voltage bearing of a kind of hobbing-type, comprise inner ring, outer ring and roller, be respectively arranged with driving cog outside described inner ring He inside outer ring, be provided with 6 ~ 10 rollers between inner ring and inner ring, described roller is cylindric, the cambered surface of roller is provided with driving cog, the diameter of roller is 6 ~ 20mm, and roller is evenly distributed between inner ring and inner ring, and the thickness of described outer ring is 3 ~ 8mm, the width of outer ring is 6 ~ 20mm, and the thickness of described inner ring is 5 ~ 10mm.The utility model can make bearing bear larger pressure, and the life-span is longer, reliable operation, and Production of bearing cost is low, easy to assembly, and maintenance cost is low.
Description
[technical field]
The utility model relates to the technical field of bearing, particularly the technical field of the withstand voltage bearing of a kind of hobbing-type.
[background technique]
The 17th century, the ball bearing of Galileo to " cage mounted ball " did description the earliest.17th century end, the Wa Luo of Britain manufactures and designs ball bearing, and to be contained on postal car the patent that fertile think of that is on probation and Britain obtains ball bearing.Dropping into the practical rolling bearing with retainer is the earliest that clock and watchmaker John Harry is inferior to 1760 for making H3 chronoscope and invents.18 the end of the century Germany hertz deliver paper about ball bearing contact stress.On the basis of hertz achievement, Germany execute Trebek, the people such as handkerchief nurse Glenn of Sweden carried out a large amount of tests, the design theory of development rolling bearing and Calculation of Fatigue Life are contributed.Subsequently, the Dinko Petrov application newton law of viscosity calculation bearing friction of Russia.First patent about ball track is that the gloomy Philips of Karma irrigates grace and obtained in 1794.1883, Friedrich Fei Sheer proposed and uses that suitable production machine grinds that size is identical, the opinion of circularity steel ball accurately, has established the basis of bearing industry.The Reynolds of Britain has carried out mathematical analysis to the discovery of Bristol, is derived reynolds equation, has from then on established the basis of hydrldynamic pressure lubrication theory.
Current bearing purposes widely, along with the maximization of machinery, the load-bearing requirements of bearing is more and more higher, roll as roller with steel ball and circle in traditional bearing, roller is easily out of shape, and bearing power is less, a kind of bearing of market demand, can bear larger pressure, simultaneously easy to assembly, maintenance cost is low.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes the withstand voltage bearing of a kind of hobbing-type, and bearing can be made to bear larger pressure, and the life-span is longer, reliable operation, and Production of bearing cost is low, easy to assembly, and maintenance cost is low.
For achieving the above object, the utility model proposes the withstand voltage bearing of a kind of hobbing-type, comprise inner ring, outer ring and roller, driving cog is respectively arranged with outside described inner ring He inside outer ring, 6 ~ 10 rollers are installed between inner ring and inner ring, described roller is cylindric, the cambered surface of roller is provided with driving cog, the diameter of roller is 6 ~ 20mm, roller is evenly distributed between inner ring and inner ring, the thickness of described outer ring is 3 ~ 8mm, and the width of outer ring is 6 ~ 20mm, and the thickness of described inner ring is 5 ~ 10mm.
As preferably, be provided with 10 rollers between described inner ring and inner ring, the diameter of roller is 12mm.
As preferably, the thickness of described outer ring is 3 ~ 8mm, and the width of outer ring is 6 ~ 20mm, and the thickness of described inner ring is 5 ~ 10mm.
The beneficial effects of the utility model: the utility model arranges driving cog respectively by inner ring, outer ring and roller being applied on bearing and on inner ring, outer ring and roller, bearing can be made to bear larger pressure, life-span is longer, reliable operation, Production of bearing cost is low, easy to assembly, maintenance cost is low.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan view of the withstand voltage bearing of a kind of hobbing-type of the utility model;
Fig. 2 is the enlarged view in A portion in Fig. 1.
In figure: 1-inner ring, 2-outer ring, 3-roller, 31-driving cog.
[embodiment]
Consult Fig. 1 and Fig. 2, the withstand voltage bearing of a kind of hobbing-type of the utility model, comprise inner ring 1, outer ring 2 and roller 3, driving cog 31 is respectively arranged with outside described inner ring 1 He inside outer ring 2,6 ~ 10 rollers 3 are installed between inner ring 1 and inner ring 1, described roller 3 is in cylindric, the cambered surface of roller 3 is provided with driving cog 31, the diameter of roller 3 is 6 ~ 20mm, roller 3 is evenly distributed between inner ring 1 and inner ring 1, the thickness of described outer ring 2 is 3 ~ 8mm, and the width of outer ring 2 is 6 ~ 20mm, and the thickness of described inner ring 1 is 5 ~ 10mm.Be provided with 10 rollers 3 between described inner ring 1 and inner ring 1, the diameter of roller 3 is 12mm.The thickness of described outer ring 2 is 3 ~ 8mm, and the width of outer ring 2 is 6 ~ 20mm, and the thickness of described inner ring 1 is 5 ~ 10mm.
The withstand voltage bearing of a kind of hobbing-type of the utility model, by inner ring 1, outer ring 2 and roller 3 being applied on bearing and on inner ring 1, outer ring 2 and roller 3, driving cog 31 is set respectively, bearing can be made to bear larger pressure, life-span is longer, reliable operation, Production of bearing cost is low, easy to assembly, and maintenance cost is low.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
