Abstract

The invention provides a double-clamping stopper bearing comprising an inner ring, an outer ring, a rolling body and a retainer, wherein the rolling surface and the vertical surface of the outer ring are both provided with snap ring grooves; the snap ring groove on each rolling surface and the snap ring groove on the vertical surface which is on the right with 30 degrees of the snap ring groove on each rolling surface form a pair of snap bayonets, and each pair of snap bayonets differs with 30 degrees and simultaneously snap; the shape of the snap ring groove is tetrahedron, sphere or other structures convenient to snap; the snap ring grooves on the rolling surface and the vertical surface can have same figures or different figures. The invention has the obvious effect that the rolling surface and the vertical surface of the outer ring are both provided with the snap ring grooves, and each pair of snap bayonets simultaneously snaps, thus effectively snapping fast operating bearings in time, reducing brake time, and obtaining obvious effect.

Description

Double-clamping stopper bearing

Technical field

The present invention relates to a kind of bearing, especially a kind of double-clamping stopper bearing.

Background technique

Bearing is the fixed member in the machinery.When other parts produce relative movement each other on axle, be used for retainer shaft the central position and control the parts of this motion, just be referred to as bearing.

Study carefully it and be used for saying be to support, promptly literal interpretation is used for holding axle, but this is the part of its effect, supports its essence and can bear radial load exactly.Also can be understood as it and be used for fixing axle.Be exactly that stationary axle makes it can only realize rotating, and control its moving axially and radially.It is exactly can not work that motor does not have the consequence of bearing at all.Because axle may be to the motion of any direction, and require axle to rotate during machine operation.Can not realize the effect of transmission theoretically, moreover, bearing also can influence transmission, must realize good lubricating in order to reduce this influence on the bearing of high speed shaft, the bearing that has itself has had lubricated, is called prelubricated bearing, and most bearing must have lubricant oil, be responsible for when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.The saying that sliding friction is changed into rolling friction is unilateral, because kind of a thing that is sliding bearing is arranged.Under certain loading, revolution that bearing is experienced before spot corrosion occurring or hour number are called bearing life.Since accuracy of manufacturing, the difference of material uniformity coefficient, even same material, the same a collection of bearing of same size uses under same operating conditions, its life-span length is also inequality.For determining the standard of bearing life, bearing life and reliability are connected.

Bearing generally is the occasion that is used for speed and weight are had strict demand, and therefore, its stopping effect is to weigh a kind of bearing quality whether important symbol.

Summary of the invention

At the problems referred to above, the invention provides a kind of double-clamping stopper bearing.

A kind of double-clamping stopper bearing, comprise inner ring, outer ring, rolling element, retainer, it is characterized in that on the face that rolls of its outer ring and facade, being equipped with locking groove, each rolls face locking groove 30 ° facade locking grooves right-hand with it and constitutes a pair of stop bayonet socket, all differ 30 ° between every pair of stop bayonet socket, the every pair of stop bayonet socket all is stop simultaneously, and the shape of locking groove can be convenient to the structure of stop for tetrahedron, spheroid or other, and facade can be identical figure or different figures with the locking groove that rolls face.

Remarkable result of the present invention is that the locking groove with plain bearing improves, be equipped with locking groove on the face that rolls of its outer ring and facade, every pair of stop bayonet socket all is stop simultaneously, can be timely and effectively the bearing of quick operation be carried out stop, and reduced period of braking, effect is remarkable.

Description of drawings

Accompanying drawing is the schematic representation of double-clamping stopper bearing rolling element

Wherein: 1, roll the face locking groove; 2, the facade locking groove.

Embodiment

The present invention will be further described below in conjunction with accompanying drawing: be equipped with locking groove on the face that rolls of the outer ring of bearing and the facade, each rolls face locking groove 1 30 ° facade locking grooves 2 right-hand with it and constitutes a pair of stop bayonet socket, all differ 30 ° between every pair of stop bayonet socket, every pair of stop bayonet socket all is stop simultaneously, promptly when bearing is carried out stop, brake valve can be fixed simultaneously and roll face locking groove 1 and its right-hand 30 ° of facade locking grooves 2, the shape of bearing locking groove can be tetrahedron, spheroid or other are convenient to the structure of stop, and facade can be identical figure or different figures with the locking groove that rolls face.

Apply the present invention in the mechanical system, the locking groove of plain bearing is improved, on the face that rolls of its outer ring and facade, be equipped with locking groove, every pair of stop bayonet socket all is stop simultaneously, can be timely and effectively the bearing of quick operation be carried out stop, and reduced period of braking, effect is remarkable, has increased antiwhip and Security.

Claims
