Abstract

The utility model relates to a wide-width high-accuracy double-row full cylindrical roller bearing, which comprises an outer ring, an inner ring and a roller. The inner ring is of a split structure and is composed of two half rings which are connected through the fixing ring, and the two half rings are both provided with sealing rings. The roller bearing is matched with mountain cable cars, improves load capacity, stability and safety of the cable cars, and simultaneously is applied to some lifting machinery.

Description

The full roller bearing of wide cut highi degree of accuracy biserial

Technical field

The utility model relates to the technical field of roller bearing, the full roller bearing of especially a kind of wide cut highi degree of accuracy biserial.

Background technique

Along with intensification 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, the visitor need 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.

The model utility content

The technical problem that the utility model will solve is: the utility model provides a kind of wide cut highi degree of accuracy biserial full roller bearing, and it is supporting with the mountain region cable car, promotes load-carrying property, stationarity, the Security of cable car, and the while also can be used on some elevating mechanisms.

The utility model solves the technological scheme that its technical problem adopted: the full roller bearing of a kind of wide cut highi degree of accuracy biserial; Have outer ring, inner ring and roller; Inner ring is a split-type structural; Inner ring is made up of two half-turns, and two half-turns connect through 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.

The beneficial effect of the utility model: full roller bearing of the wide cut highi degree of accuracy biserial of the utility model and mountain region cable car are supporting, promote load-carrying property, 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 under the weather of high temperature, cold, sleet, can both plays dustproof effect; The neutral position of outer ring and the neutral position of inner ring all offer oil hole, are used for termly in bearing, injecting specific lubricant grease, guarantee the flexibility of revolution of bearing.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model.

1. outer rings among the figure, 2. inner ring, 3. roller, 4. retaining ring, 5. seal ring.

Embodiment

Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

The full roller bearing of wide cut highi degree of accuracy biserial as shown in Figure 1 has outer ring 1, inner ring 2 and roller 3, and inner ring 2 is a split-type structural, and inner ring 2 is made up of two half-turns, and two half-turns connect through 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 termly in bearing, injecting specific lubricant grease, 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.

The full roller bearing of this wide cut highi degree of accuracy biserial 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 to produce edge effect, 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 the assembling of this bearing, must inner ring 2 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 or the like;

Five, seal ring 5 can prevent dust under rugged environment, 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, like the passenger for a long time, seal ring 5 is also indeformable.

With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
