The axial and radial combination bearing has the beneficial effects of not only meeting the axial and radial high rigidity requirement of the bearing, but also reducing the requirements of low friction and high lubrication of the products.
Description
Technical field
The utility model relates to machine tool field such as accurate digital control milling machine, boring machine, machining center, relates in particular to a kind of high-accuracy, high rigidity shaft radial combination bearing.
Background technique
Continuous development along with China's machine industry, especially machine tool structure is brought in constant renewal in, the required precision of worktable such as some accurate digital control milling machines, boring machine, machining center is more and more higher, and the old airframe bearing that supports precision stage has been difficult to satisfy the requirement of the highi degree of accuracy of lathe, low friction, high rigidity.
At the requirement of precision stage, urgent need will provide a kind of novel combination bearing, overcomes the shortcoming of old infrastructure product, adapts to the demand in precision machine tool field.
The model utility content
The purpose of this utility model provides a kind of high-accuracy, high rigidity shaft radial combination bearing, and the diameter of axle that had both satisfied bearing has satisfied the high lubricated requirement of the low friction of product again to high rigidity requirement.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of high-accuracy, high rigidity shaft radial combination bearing, mainly by seat ring, first blowout patche, second blowout patche, down arrange axial roller, on arrange axial roller, self-locking screw, down arrange retainer, on arrange retainer and radial roller is formed, first blowout patche and second blowout patche connect into integral body by the self-locking screw, form radially roller surface of two axial roller surfaces and; Seat ring has three roller surfaces, axially descends roller surface to be connected by arranging axial roller down with first blowout patche, axially goes up roller surface to be connected by the axial roller of last row with second blowout patche, and seat ring radially roller surface is connected by radial roller with first blowout patche; Under arrange axial roller and be connected with following row's retainer, on arrange axial roller and be connected with last row's retainer.
The beneficial effects of the utility model are: the diameter of axle replaces existing thrust and radial bearing to the combination form structure, and axial two row's ultraprecise thrust rollers have accurate retainer, and axial high rigidity requirement is satisfied in outer ring, L-cross section ring, the pre-interference in blowout patche assembling back; The L-cross section ring and the outer ring of the two rib raceways of band forms radially pre-interference, satisfies radially high rigidity requirement; The eccentric pocket hole novel high-strength nylon cages of taking turns had both guaranteed effectively separating of retainer and raceway, rolling element is gone slick in retainer pocket hole, steadily, flexibly, thereby realized the low friction of product requirement; The lubricant oil slotted eye that outer ring, the ring design of L-cross section have lubricating function again is to satisfy the lubricating requirement fully again of product; The set screw of design band self-locking screw thread packing ring makes the fastening safety of bearing parts.
