Abstract
A kind of high-mechanic anti-lock bearing, including centre circle, retainer, rolling element and inner ring, centre circle is set on the outside of inner ring, rolling element is slidably arranged between centre circle and inner ring by retainer and forms rolling bearing structure, the outer sheath of centre circle is equipped with freely slidable outer ring, the rolling bearing structure and outer ring cooperatively forms sliding bearing structure, be formed as the gap that sliding bearing structure provides lubricating oil between centre circle and outer ring by way of clearance fit, the utility model is less than the moment of friction of sliding bearing due to cylinder roller bearing moment of friction, therefore in bearing rotation process, cylinder roller bearing preferentially rotates, when cylinder roller bearing operates failure, and locking occurs, sliding bearing starts to rotate, locking phenomenon occurs so as to completely avoid bearing and shafting, effectively reduce property loss, it ensure that personnel safety.
Description
Technical field
The utility model is related to technical field of bearings, more particularly, to a kind of high-mechanic anti-lock bearing.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is the mechanical rotary body of support, is reduced
Friction coefficient in its motion process, and ensure its rotating accuracy.Can fail in use, failure refer to bearing or
Shafting locking does not turn, situation about not turning if there is bearing or shafting locking will because of dangerous or accident, therefore bearing or
Shafting locking does not turn to be exactly a kind of extremely hazardous failure performance, be easy to cause very serious economic loss and casualties.
Utility model content
The purpose of this utility model is to solve bearing of the prior art in use since bearing failure causes
Bearing or shafting locking do not quote the problem of hair is dangerous, a kind of high-mechanic anti-lock bearing is provided.
The deficiency of the utility model to solve above-mentioned technical problem, used technical solution are：
A kind of high-mechanic anti-lock bearing, including centre circle, retainer, rolling element and inner ring, centre circle is set on the outside of inner ring,
Rolling element is slidably arranged between centre circle and inner ring by retainer and forms rolling bearing structure, and the outer sheath of centre circle is equipped with can be certainly
By the outer ring slided, the rolling bearing structure and outer ring cooperatively form sliding bearing structure, pass through between centre circle and outer ring
The mode of clearance fit is formed as the gap that sliding bearing structure provides lubricating oil, the frictional force born due to rolling bearing structure
Frictional force between rolling element and inner ring, and it is frictional force between centre circle and outer ring that sliding bearing structure, which is born, rolling element
Between inner ring and centre circle and outer ring material is identical but the former is contacted as linear contact, latter contacts are face contact, because before this
The frictional force being subject to of person is small, therefore the active force between centre circle and outer ring can not overcome between the two quiet under normal circumstances
Frictional force is rotated, and the arm of force of sliding bearing structure is more than the arm of force of rolling bearing structure, therefore cylinder roller bearing
Moment of friction is less than the moment of friction of sliding bearing, therefore in bearing rotation process, cylinder roller bearing preferentially rotates, and works as cylinder
When locking occurs for roller bearing operating failure, due to being fixed as one between rolling element and inner ring, at this time between centre circle and outer ring
Active force overcome stiction between the two, so as to which sliding bearing starts to rotate.
The rolling element is cylindrical rolling element, by the driving of cylinder roller bearing so as to ensure that the bearing is suitable for
The environment of high-mechanic.
The beneficial effects of the utility model are：Since cylinder roller bearing moment of friction is less than the frictional force of sliding bearing
Square, therefore in bearing rotation process, cylinder roller bearing preferentially rotates, when cylinder roller bearing operates failure, and locking occurs,
Sliding bearing starts to rotate, and locking phenomenon occurs so as to completely avoid bearing and shafting, effectively reduces property loss, ensures
Personnel safety.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Diagram label：1st, outer ring；2nd, centre circle；3rd, retainer；4th, rolling element；5th, inner ring.
Specific embodiment
Shown in Fig. 1, specific embodiment is as follows：
A kind of high-mechanic anti-lock bearing, including centre circle 2, retainer 3, rolling element 4 and inner ring 5, centre circle 2 is set in inner ring
5 outsides, rolling element 4 are slidably arranged between centre circle 2 and inner ring 5 by retainer 3 and form rolling bearing structure, the rolling
Body 4 is cylindrical rolling element, and the outer sheath of centre circle 2 is equipped with freely slidable outer ring 1, the rolling bearing structure and outer ring
1 cooperatively forms sliding bearing structure, and being formed as sliding bearing structure by way of clearance fit between centre circle 2 and outer ring 1 carries
For the gap of lubricating oil, the frictional force of the frictional force born due to rolling bearing structure between rolling element 4 and inner ring 5, and slide
What moving axis bearing structure was born is frictional force between centre circle 2 and outer ring 5, between rolling element 4 and inner ring 5 and 5 material of centre circle 2 and outer ring
Identical but the former contact is linear contact, and latter contacts are that face contacts, therefore the former frictional force being subject to is small, therefore just
Active force in the case of often between centre circle 2 and outer ring 5 can not overcome stiction between the two to be rotated, and sliding axle
The arm of force of bearing structure is more than the arm of force of rolling bearing structure, therefore cylinder roller bearing moment of friction is less than the friction of sliding bearing
Torque, therefore in bearing rotation process, cylinder roller bearing preferentially rotates, and locking occurs when cylinder roller bearing operates failure
When, due to being fixed as one between rolling element and inner ring, the active force between centre circle and outer ring overcomes between the two quiet at this time
Frictional force, so as to which sliding bearing starts to rotate.
Technical solution and embodiment and non-limiting cited by the utility model, with the skill cited by the utility model
Art scheme and embodiment are equal or effect same approach is all in the range of the utility model is protected.
