Abstract
The invention relates to a wide width high-accuracy double-row circular cylinder roller bearing. The wide width high-accuracy double-row circular cylinder roller bearing is provided with an outer ring, an inner ring and a roller, wherein the inner ring is in a split type structure and is composed of two semi-rings, the two semi-rings are connected through a fixed ring, and both the semi-rings are provided with a sealing ring. The roller bearing is matched with a mountain cable car, the load-bearing, stability and safety of the cable car is improved, and meanwhile the roller bearing can be applicable to some lifting machinery.
Description
Technical field
The present invention relates to the technical field of roller bearing, especially a kind of wide cut highi degree of accuracy bearing with double row of full rollers.
Background technique
Along with the intensification in domestic, international tourism market, each tourist attractions a slice is good, and particularly the chain of mountains is precipitous, the mountain peak that height above sea level is higher, and the visitor need to take advantage of a mountain region cable car, from a sight spot to another sight spot.The annual requirement of mountain region cable car is according to statistics more than 1,000,000, and the roller bearing consumption that matches with it reaches 8,000,000 covers.
Summary of the invention
The technical problem to be solved in the present invention is: the invention provides a kind of wide cut highi degree of accuracy bearing with double row of full rollers, it and mountain region cable car are supporting, promote load-carrying, stationarity, the Security of cable car, also can be used on some elevating mechanisms simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of wide cut highi degree of accuracy bearing with double row of full rollers, have outer ring, inner ring and roller, inner ring is split-type structural, and inner ring is comprised of two half-turns, two half-turns connect by retaining ring, on two half-turns, seal ring are installed all.
Further: the neutral position of outer ring and the neutral position of inner ring all offer oil hole.
Further: the material of seal ring is nitrile rubber or nylon PA66 or polyurethane.
Further: the convexity of roller is 0.005～0.007mm.
Further: the axial internal clearance of roller bearing is 0.1～0.3mm, and radial internal clearance is 0.04～0.06mm.
Beneficial effect of the present invention: a kind of wide cut highi degree of accuracy bearing with double row of full rollers of the present invention and mountain region cable car are supporting, promote load-carrying, stationarity, the Security of cable car, also can be used on some elevating mechanisms simultaneously; On two half-turns, seal ring is installed all, no matter can plays dustproof effect under the weather of high temperature, cold, sleet; The neutral position of outer ring and the neutral position of inner ring all offer oil hole, are used for injecting specific lubricant grease termly in bearing, guarantee the flexibility of revolution of bearing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1. outer rings in figure, 2. inner ring, 3. roller, 4. retaining ring, 5. seal ring.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of wide cut highi degree of accuracy bearing with double row of full rollers as shown in Figure 1 has outer ring 1, inner ring 2 and roller 3, and inner ring 2 is split-type structural, and inner ring 2 is comprised of two half-turns, and two half-turns connect by retaining ring 4, on two half-turns, seal ring 5 are installed all.
Wherein the neutral position of the neutral position of outer ring 1 and inner ring 2 all offers oil hole, is used for injecting specific lubricant grease termly in bearing, guarantees the flexibility of revolution of bearing.The material of seal ring 5 is nitrile rubber or nylon PA66 or polyurethane.The convexity of roller 3 is 0.005～0.007mm.The axial internal clearance of roller bearing is 0.1～0.3mm, and radial internal clearance is 0.04～0.06mm.
This a kind of wide cut highi degree of accuracy bearing with double row of full rollers has following processing and assembling and requires:
One, for guaranteeing machining accuracy, numerically controlled lathe is used in the Vehicle Processing of outer ring 1 and inner ring 2 without exception, and numerically control grinder is used in mill processing without exception;
Two, in order to improve the bearing capacity of bearing, guarantee bearing safety, reliable, avoid roller 3 two ends generation edge effects, roller 3 is designed to crowned roller for this reason, and this crowned roller is that circular arc modified line bus is repaiied the type roller;
Three, during this bearing assemble, inner ring 2 must be cutd open from middle one is two, the roller 3 of just packing into, the design of groove for this reason, must guarantee bearing intensity, cut open when splitting disposable success and connect into one when whole, coaxality is 0;
Four, retaining ring is that two half-turns with inner ring 2 couple together, and becomes as a whole, guarantees overall performance, the safety, reliable of bearing, and the method for connection has roll extrusion, turgor pressure, extruding etc.;
Five, seal ring 5 under rugged environment, can prevent dust, and like rain, snow weather, includes the place that mud occurs; Under high temperature, arctic weather, seal ring 5 is indeformable; Under the heavy load effect, when as many in the passenger, seal ring 5 is also indeformable.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
