Abstract
The utility model relates to a single-row center-adjusting ball bearing composed of an outer ring, a retainer, a rolling body, an inner ring, etc., wherein, the inner ring adopts a single-row groove inner ring and is provided with the single-row rolling body; the retainer adopts a trough-shaped or wavy or easy production entity retainer and is provided with a double-face dust cover or a double-face sealing ring to make single-row center-adjusting ball bearings with various structures. The utility model has the advantages of labor saving, material saving, low cost, low price, easy guaranteed accuracy, etc.
Description
The utility model belongs to mechanical transmission component, is applicable to selfaligning ball bearing and bearing with spherical outside surface.
Existing selfaligning ball bearing (is example with 1000 type double row self aligning ball bearings) adopts biserial ditch inner ring, the biserial rolling element is housed on it, and retainer adopts chrysanthemum shape or certain herbaceous plants with big flowers shape retainer, take a lot of work, take material, cost height, adopt the extremely difficult processing of these two kinds of its moulds of retainer, and cost an arm and a leg, bearing accuracy is difficult for guaranteeing.Have much room for improvement.
The utility model aims to provide that the single-row ditch inner ring of a kind of employing, single-row rolling element, saving of labor, material-saving, cost are low, low price, precision easily guarantee the single-row selfaligning ball bearing of multiple structure.
The utility model is made up of outer ring, retainer, rolling element, inner ring.Its inner ring adopts single-row ditch inner ring, and single-row rolling element is housed.The solid cage that retainer adopts grooved, shape wave or is easy to make.And can make the single-row selfaligning bearing of multiple structure.
Owing to adopt single-row ditch inner ring to replace biserial ditch inner ring, except that reducing work hours, reduce materials consumption and cost, its product precision also is easy to guarantee.Replace the biserial rolling element with single-row rolling element, form structure is constant, possesses the function (being aligning) of existing selfaligning ball bearing.And it is big that bearing interior space becomes, and can be made into the single-row selfaligning ball bearing of the multiple structure that installs two-sided dust cover or dual face seals circle additional, to adapt to the ambient conditions bad working environment.The solid cage that adopts flute profile, shape wave or be easy to make not only overcomes the extremely difficult processing of chrysanthemum shape, certain herbaceous plants with big flowers shape retainer mould, expensive drawback, and can increase sphere diameter, to improve its dynamic load rating, thereby reach the purpose that improves bearing life, alternative in some aspects bearing with spherical outside surface has enlarged application.
Below in conjunction with accompanying drawing embodiment of the present utility model is narrated:
Accompanying drawing 1: single-row selfaligning ball bearing structural drawing
Accompanying drawing 2: the single-row selfaligning ball bearing structural drawing that installs two-sided dust cover additional
Accompanying drawing 3: the single-row selfaligning ball bearing structural drawing that installs the dual face seals circle additional
Present embodiment is except that installing two-sided dust cover 5 additional on embodiment 1 fundamental mode, all the other structures are identical.This single-row selfaligning ball bearing is applicable to the ambient conditions bad working environment.
Present embodiment is except that installing additional the dual face seals circle 5 ' on the fundamental mode of enforcement 1, and all the other structures are identical.The single-row selfaligning ball bearing of this structure is adapted to the dense working environment of extraneous dust.
The utility model compared with the prior art, it is low to have a saving of labor, material-saving, cost, low price, precision is easy to the characteristics such as assurance. It is a kind of economical and practical, bearing that application is wide.
