Description

Adjustable cone roller bearing axial direction positioning device

Technical field

The present invention relates to the machinery field, relate in particular to a kind of adjustable cone roller bearing axial direction positioning device.

Background technique

At present, usually design is to adopt circular distance ring to carry out axially locating to tapered roller bearing, adopts this orientation type, because distance ring bears very big active force, produce very big frictional force, the inside play of back tapered roller bearing just can't be by adjusting well for installing and locating.Because the error that produces in manufacturing, the installation process is uncontrollable, causes the tapered roller bearing Location accuracy to guarantee, seriously reduces the working life of tapered roller bearing.Therefore be necessary existing circular cone roller bearing positioning device is improved,, guarantee the best play of bearing, improve bearing working life in the hope of carrying out axially locating to bearing reliably.

Summary of the invention

At the problems referred to above, the object of the present invention is to provide a kind of best play of tapered roller bearing of adjusting in real time to eliminate the influence of manufacturing and alignment error, improve the adjustable cone roller bearing axial direction positioning device in the working life of bearing bearing inside play.

For achieving the above object, the scheme that the present invention adopts is: a kind of adjustable cone roller bearing axial direction positioning device, its difference is: it includes bow and lacks axle, bow lacks the axle two axial ends and is provided with arcuate indentation, frame is installed at the arcuate indentation place, bow lacks axle and is provided with the shaft shoulder, and tapered roller bearing and positioning bearing inner ring are installed by shaft shoulder place, and bow lacks the inner oil filler pipe that injects lubricant oil that is provided with of axle; The saturating lid of positioning bearing outer ring is equipped with in the tapered roller bearing both sides, and the outer ring is equipped with wheel or bearing support; Bow lacks axle distance ring is housed, distance ring is provided with and bends the bow segmental breach that lacks axle notch geometry coupling, the distance ring head end props up the tapered roller bearing inner ring, and the distance ring end lacks the axle head baffle plate by bow and pushes against, and the scarce axle head baffle plate of bow is installed in bow by the adjusting bolt and lacks axial end.

Described distance ring and bow lack the diameter of axle to 1～2mm gap is arranged.

Described distance ring end face exposes the scarce axial end 5～10mm distance of bow, and the distance ring bow lacks shoulder end face and the scarce shoulder end face axial spacing of the scarce axle bow of bow is 5～10mm.

Inner ring of the present invention is located to adopt to bend scarce distance ring, bend scarce axle and bend scarce axle head baffle plate cooperation and is positioned, by regulating the inside play that bolt can the real time altering tapered roller bearing, the influence that the abatement apparatus foozle produces the Bearing Installation precision, significantly improve tapered roller bearing working life, entire mechanism is simple and practical, is easy to promote.

Embodiment

For understanding the present invention better, below in conjunction with the drawings and specific embodiments technological scheme of the present invention is described further, referring to Fig. 1 to Fig. 7:

By a kind of adjustable cone roller bearing axial direction positioning device of the invention process, it includes bow and lacks axle 2, bow lacks axle 2 left and right sides two axial ends and is equipped with arcuate indentation, the arcuate indentation place is installed on the frame by clamping bolt, arcuate indentation increases the area of contact between axle and frame, thereby increased linking intensity, in order to reduce vibration, be provided with backing plate 3 between scarce axle 2 of bow and frame simultaneously.Bow lacks axle 2 and is provided with the shaft shoulder, and tapered roller bearing 1 is installed at shaft shoulder place, and the shaft shoulder is used for the inner ring of setting circle taper roller bearing 1 one sides, injects lubricant oil in order to give tapered roller bearing 1, and bow lacks axle 2 inside and is provided with oil filler pipe 10.Tapered roller bearing 1 both sides are equipped with and are covered 8, and the outer ring is equipped with wheel 9 or bearing support, cover 8 thoroughly and are provided with projection in position, tapered roller bearing 1 outer ring, and snag axis is to the positioning bearing outer ring.

Tapered roller bearing 1 one sides have bow to lack axle 2 shaft shoulder axially locating, opposite side dependence distance ring 6 location, and distance ring 6 is installed in the opposite side that bow lacks the relative shaft shoulder on the axle 2.Distance ring 6 one ends are the bow segmental breach, and this breach lacks axle 2 breach with bow and aligns to frame vacating space to be installed.Distance ring 6 head ends prop up tapered roller bearing 1 one side inner rings, and distance ring 6 ends lack axle head baffle plate 4 by bow and push against, and the scarce axle head baffle plate 4 of bow is installed in bow by adjusting bolt 5 and lacks axle 2 end faces.

In order to regulate the inside play of tapered roller bearing 1, distance ring 6 lacks axle 2 with bow axially must be adjustable, so distance ring 6 and bow lack axle 2 bows and lack shoulder and 1～2mm gap is arranged between radially, distance ring 6 ends expose the scarce axle of bow 2 end faces 5～10mm distance, and distance ring bends scarce shoulder 12 and the scarce scarce shoulder of bow of bow 11 axial distances are 5～10mm.Bolt 5 is regulated in turn just can adjust the axial position that distance ring 6 opposing arches lack axle 2 easily, thereby the inside play that changes tapered roller bearing 1 is guaranteeing the Bearing Installation precision, raising bearing working life.After adjusting is finished, tighten fixedly distance ring 6 positions of clamping bolt, be connected, lack axle 2 so distance ring 6 is given axial force transmission to bend because distance ring 6 lacks axle 2 by clamping bolt with adjusting bolt 5 and bow.

Above disclosed only is preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalence of being done according to the present patent application claim changes, and still belongs to protection scope of the present invention.
