Abstract
The utility model relates to an omni-directional bearing which can not only withstand longitudinal force, but also bear axial force. An inner ring and an outer ring of the omni-directional bearing are sheathed together, only a sliding gap is reserved between the inner ring and the outer ring, a circular hole capable of enabling a steel ball to be mounted therein is processed in the middle of the joint surface between the two rings, semi-circular grooves are presented by the circular hole on the two rings, a threaded hole capable of enabling another steel ball to be mounted therein is processed in the position where the outer diameter of the outer ring is aligned with the center of the semi-circular groove, lubricating butter is simultaneously loaded when the steel ball is mounted, then a screwed plug is used for blocking the threaded hole, and a studding stable pin is processed between the outer diameter of the screwed plug and the inner diameter of the threaded hole.
Description
Technical field
The utility model relates to a kind of bearing, is applied in mechanical field.
Technical background
At present, it all is that one cover plane bearing is resisted longitudinal force with three cover bearings that existing technology is subjected to the transmission shaft of longitudinal force again to existing axial force, bears axial force with two cover rolling bearings again.This is because the steel ball rolling rail on inside and outside two circles of rolling bearing is too shallow, only contains the fraction of steel ball, does not have vertical focusing surface, if dark just do not assemble, so rolling bearing can only be born axial force, and can not resist longitudinal force.With three cover bearings the accessory of three cover bearings just need be set, as: establish a sleeve-bearing, the length of axle will extend more, how will establish a step with a cover bearing on axle more, and the diameter of axle just need overstriking, and this not only takes material, takes a lot of work and also take the place.
Summary of the invention
In order to overcome that existing bearing can only be resisted longitudinal force and the problem that can not bear axial force, the utility model provides a kind of omnidirectional bearing, and this omnidirectional's bearing can not only be born longitudinal force, and can also bear axial force.
A kind of omnidirectional bearing is nested together by outer ring and inner ring, and glade plane space is stayed in the centre, and the every circle in center portion accounts for 1/2nd in the middle of two circles, processes a circular hole, and this circular hole is the steel ball rolling rail, and this track all is rendered as a half slot on each circle; Align the center of half slot in the outer ring, process the silk hole of the steel ball of packing into, so that the loading and unloading steel ball, this hole is the steel ball access way, and plug is installed in the hole, between plug external diameter and silk hole internal diameter, processes a studding and surely sells.
A kind of omnidirectional bearing, it is the self-bearing type bearing, it is characterized in that: process half slot on axle, process half slot on bearing support, plug is machined in the top of bearing support.
This omnidirectional's bearing is nested together by the outer ring and the inner ring of bearing, two circles are highly consistent, glade plane space is stayed in the centre, two circles close face the centre process a circular hole that can hold steel ball, this circular hole respectively accounts for 1/2nd on two circles, Here it is " hiding steel ball track ", this track is presented on two circles, on each circle is exactly a half slot, aligns the center of half slot in the outer ring, processes the silk hole of the steel ball of packing into, the lubricated butter of packing in the lump when packing steel ball into, with plug this hole is blocked afterwards, the length of plug is that the outer end is consistent with the outer diameter and arc surface of outer ring, and will process the plug silk cutter groove of a rotation usefulness, again between plug external diameter and silk hole internal diameter, process steady Xiao of studding, this steady Xiao's outer end is also consistent with the outer diameter and arc surface of outer ring, and processes steady Xiao's silk cutter groove of rotation usefulness.This steady Xiao is fixing plug back-off not both, also can accurately limit the precession degree of depth of plug; The interior edge face of this plug is an arc nest, the radian of this arc nest is consistent with the external diameter radian of the half slot of outer ring internal diameter, could neither hinder the screw-in of plug like this, can also guarantee that steel ball in the running can be stressed glossily and pass through, the material of this plug and hardness are consistent with bearing, this structure called after: " steel ball access way ".The principle of above omnidirectional bearing can be processed into the self-bearing type bearing under special circumstances.It is characterized in that: the half slot of inner ring is machined on the axle, the half slot of outer ring is worked on the bearing support, plug is worked into the top of bearing support, and this spline structure is simpler, and effect is identical, but material and hardness all will reach the requirement of bearing.
Description of drawings
Accompanying drawing is omnidirectional's bearing structure schematic representation;
Wherein, the 1st, outer ring, the 2nd, steel ball, the 3rd, inner ring, the 4th, plug, the 5th, studding surely sell, the 6th, plug silk cutter groove, the 7th, studding is surely sold a cutter groove.
Embodiment
One, material and hardness all need by bearing requirement setting;
Two, the machining accuracy to each parts also must conform with the bearing requirement;
Three,, should be placed on the critical role of processing outer ring to the processing of plug.Suggestion the processor process by following process sequence arrangement: 1, at first process the plug body, the outside dimension of plug is wanted accurately, to guarantee degree of tightness appropriateness when mounted; 2, the radian of processing plug interior edge face circular arc nest must be consistent with the external diameter circular arc of the half slot of outer ring internal diameter; When 3, processing the outer end of plug, need reserve machining allowance, in order to outer bowlder integral body processing again in the processing outer ring; When 4, processing outer ring body, should process the internal diameter and the half slot of outer ring earlier; 5, the silk hole of processing plug; When 6, screwing in plug, make the interior edge face of plug equal with the external diameter of outer ring internal diameter half slot, this point is extremely important, because the interior edge face of this plug will become the part of half slot, when assembling, preferably do one and be exclusively used in the corresponding to model of this half slot, crouch in half slot, just qualified when the interior edge face of plug touches model and fits like a glove; 7, machining allowance also should be left in the outer end that adds apt pin; When 8, processing the external diameter of outer ring, process with the outer end of plug and steady pin is whole; 9, process plug silk cutter groove and steady pin silk cutter groove at last.
Four, can process fully with the equipment of processing plain bearing.
Claims (1)
1. can resist omnidirectional's bearing that longitudinal force can be born axial force again for one kind, inner ring and outer ring with omnidirectional's bearing is nested together exactly, glade plane space is only stayed in the centre, between Liang Quan close face the middle part process the circular hole of the steel ball of packing into, it is exactly to each have a half slot that this circular hole is presented on two circles, external diameter in the outer ring aligns the center of half slot, process the silk hole of the steel ball of packing into, packing into blocks the silk hole with plug behind the steel ball, processes a studding and surely sell between the internal diameter in the external diameter of plug and silk hole.
