Abstract
The utility model discloses a two ditch swing rod bearing, including the inner circle, the inner circle has cup jointed the outer lane outward, first steel ball connection low groove, second steel ball connection low groove have been offered respectively to interior circling, set up first steel ball on the outer lane respectively and connected upper groove, second steel ball connection upper groove, first steel ball is connected the low groove and is connected with first steel ball and installs first steel ball between the upper groove, the second steel ball is connected the low groove and is connected with the second steel ball and installs the second steel ball between the upper groove, install the holder in the outer lane, install first steel ball, second steel ball in the holder respectively, first steel ball has cup jointed first abrasionproof cover outward, the second steel ball has cup jointed second abrasionproof cover outward. A two ditch swing rod bearing, its simple structure, simple to operate avoids steel ball diameter runout through the cooperation use of abrasionproof cover and spacing spring, has improved the life of bearing in the time of reduction in production cost.
Description
Technical field
This utility model relates to a kind of double; two ditch Oscillating lever bearing.
Background technology
Oscillating lever bearing is a kind of common part in reciprocating sow, and it includes bearing core, cartridge housing, the steel ball that is sandwiched between described bearing core and cartridge housing, and described steel ball is kept by retainer.The Oscillating lever bearing used at present is single-groove bearing, and its structural strength of single-groove bearing is low；According to double; two ditch bearings, mutual circular runout greatly then improves processing request height, production cost.
Utility model content
The purpose of this utility model is in that to provide a kind of double; two ditch Oscillating lever bearings, and its simple in construction is easy for installation, by wearing bush and limit spring with the use of avoiding steel ball circular runout, improve the service life of bearing while reducing production cost.
In order to achieve the above object, the technical solution of the utility model is:
A kind of double; two ditch Oscillating lever bearing, including inner ring, it is socketed with outer ring outside described inner ring, described inner ring offers the first steel ball respectively and connects low groove, the second steel ball connection low groove, described outer ring offers the first steel ball respectively and connects upper groove, the second steel ball connection upper groove, first steel ball is installed between described first steel ball connection low groove and the first steel ball connection upper groove, between described second steel ball connection low groove and the second steel ball connection upper groove, the second steel ball is installed；Retainer is installed in described outer ring, in described retainer, is separately installed with the first steel ball, the second steel ball, be socketed with the first wearing bush outside described first steel ball, outside described second steel ball, be socketed with the second wearing bush.
Between described first wearing bush and the second wearing bush, limit spring is installed.
Described outer ring is connected with cylindrical bar, offers lubrication channel in described cylindrical bar, and described lubrication channel is connected with retainer installation.
Offer inner ring groove in described inner ring, sealing ring is installed in described inner ring groove, outside described sealing ring, is coated with wearing layer.
The beneficial effects of the utility model are: a kind of double; two ditch Oscillating lever bearings, and its simple in construction is easy for installation, by wearing bush and limit spring with the use of avoiding steel ball circular runout, improve the service life of bearing while reducing production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
A kind of double; two ditch Oscillating lever bearing as shown in Figure 1, including inner ring 1, it is socketed with outer ring 2 outside described inner ring 1, described inner ring 1 offers the first steel ball respectively and connects low groove the 11, second steel ball connection low groove 12, described outer ring 2 offers the first steel ball respectively and connects upper groove the 13, second steel ball connection upper groove 14, described first steel ball connects low groove 11 and is connected between upper groove 13 with the first steel ball and is provided with the first steel ball 15, and described second steel ball connects low groove 12 and is connected between upper groove 14 with the second steel ball and is provided with the second steel ball 16；Retainer 3 is installed in described outer ring 2, in described retainer 3, is separately installed with first steel ball the 15, second steel ball 16, be socketed with the first wearing bush 17 outside described first steel ball 15, outside described second steel ball 16, be socketed with the second wearing bush 18.The setting of the first wearing bush 17 and the second wearing bush 18 can improve the service life of the first steel ball 15 and the second steel ball 16.
Between described first wearing bush 17 and the second wearing bush 18, limit spring 6 is installed.Arranging of limit spring 6 ensures that steel ball avoids its circular runout when properly functioning.
Described outer ring 2 is connected with cylindrical bar 4, offers lubrication channel 5 in described cylindrical bar 4, and described lubrication channel 5 is connected with retainer 3 installation.The lubricity that raising steel ball and inner ring 1, outer ring 2 are set of lubrication channel 5.
Offer inner ring groove 21 in described inner ring 1, sealing ring 22 is installed in described inner ring groove 21, outside described sealing ring 22, is coated with wearing layer 23.
A kind of double; two ditch Oscillating lever bearings of the present embodiment, its simple in construction, easy for installation, by wearing bush and limit spring with the use of avoiding steel ball circular runout, improve the service life of bearing while reducing production cost.
