The mounting device and installation method of taper roller bearing.
Background technique
It is usually used to wear pin retainer to keep taper roller for large-scale single-row tapered roller bearing.But it uses
Wear pin retainer need to process in taper roller for wear the pin of pin retainer across hole, therefore such bearing
Processing cost is high.
In contrast, taper roller is kept to can reduce cost using segmentation retainer.But it is segmented retainer at present
It is generally used in above the double row tapered roller bearing using integral installation mode.For having used the single-row circle of segmentation retainer
Taper roller bearing (referring to Fig. 1), due to there is no device that inner assembly (roller 2, retainer 3 and inner ring 1) is fixed together, and by
It is usually that inner assembly and outer ring are installed separately (that is, inner assembly and outer ring are first respectively installed to axis in single-row tapered roller bearing
On bearing block, then cooperate inner assembly and outer ring), so when inner assembly is installed on axis, roller 2 and retainer
3 are easy to slide from the raceway of inner ring 1.Based on this reason, it is segmented retainer and is rarely applied to single-row tapered roller bearing.
Summary of the invention
In view of the above-mentioned problems of the prior art, the present invention is intended to provide a kind of single-row circular cone rolling for having used segmentation retainer
The mounting device and installation method of sub- bearing, so that roller and retainer be not from interior when inner assembly is installed on axis
Raceway is enclosed to slide.
In order to achieve the above-mentioned object of the invention, the present invention can adopt the following technical scheme that.
A kind of mounting device of bearing is used to install and use the single-row tapered roller bearing of segmentation retainer, described
Mounting device includes: baffle portion, is used to that taper roller and the segmentation retainer to be prevented to skid off the single-row tapered roller axis
The raceway of the inner ring held；And mounting portion, it is used to the mounting device being fixed to the inner ring.
Preferably, the width of the baffle portion is greater than the gap between the adjacent taper roller.
Preferably, the ratio of the axial length of the length on the extending direction of the baffle portion and the segmentation retainer is 1/
3 or more and 1 or less.

1/2 and less than 1.
Preferably, the mounting device further includes interconnecting piece, and the interconnecting piece is for connecting the baffle portion and the peace
Dress portion, the interconnecting piece and the baffle portion it is at an angle extend so that the baffle portion and the taper roller are substantially flat
Row.
Preferably, the length on the extending direction of the interconnecting piece is set such that the taper roller and the baffle portion
Between minimum range be 2mm to 3mm.
Preferably, the mounting portion extends simultaneously from the interconnecting piece to the direction opposite with the extending direction of the baffle portion
And shape is at an angle between the mounting portion and the interconnecting piece, so that the periphery of the rib of the mounting portion and the inner ring
Face is substantially parallel.
Preferably, the mounting portion is provided with the thickness extension through the mounting portion, the through-hole that passes through for screw.
A kind of installation method of bearing has installed and used the single-row tapered roller of segmentation retainer using mounting device
Bearing, the installation method include the following steps:
The inner ring that fixed part is provided at large end face of the single-row tapered roller bearing is face-down with the big end
It is placed on platform,
Taper roller and the segmentation retainer on code on the inner ring,
The mounting portion of the mounting device is fixed on to the fixed part of the inner ring, thus by the gear of the mounting device
Plate portion prevents the taper roller and the segmentation retainer from skidding off the raceway of the inner ring.
Preferably, will by the taper roller that the mounting device is fixed together, the segmentation retainer and
After the inner ring is installed on axis and makes its outer ring cooperation with the single-row tapered roller bearing, removed from the inner ring
The mounting device.
The baffle portion of mounting device and installation method through the invention, mounting device by taper roller and is segmented retainer
It is maintained in inner ring raceway, it is therefore prevented that taper roller and segmentation retainer fall or skid off.It is thereby achieved that segmentation has been used to protect
Hold the installation of the single-row tapered roller bearing of frame.
