Abstract
The utility model discloses a kind of oscillating bearing roll riveting erecting device that three taper rollers are housed.The top of the die inner ring (1) of described device is Morse taper shank, and its lower surface is processed as tapered roller raceway; Three equally distributed cone tanks of bottom processing of die retainer (8), three taper rollers (9) are arranged on respectively in the cavity of the cone tank formation bottom die inner ring (1) lower surface tapered roller raceway and die retainer (8), thrust ball bearing II (7), the thrust ball bearing I (4) of described die inner ring (1) lower end shoulder, round nut I (2), round nut II (3) are axially fixed in die inner ring (1) above by connecting flange (6), and described die retainer (8) connects with connecting flange (6) by hexagon socket cap head screw (5).The utility model adopts three taper rollers to make the oscillating bearing flange of outer ring fluting, has improved the service life of this roll riveting device and the roll riveting installation effectiveness of oscillating bearing.
Description
Technical field
The utility model relates to a kind of oscillating bearing roll riveting erecting device, adopts three taper roller roll extrusion oscillating bearing outer ring notches, and because taper roller is solid, intensity is high, thereby improves the service life of rolling element.
Background technology
Oscillating bearing, also referred to as spherical bearing, has a wide range of applications in fields such as Aero-Space, engineering machinery, water conservancy and hydropowers.And the installation of oscillating bearing is fixing, directly affect its service life, fixing improper if oscillating bearing is installed, easily produce the phenomenon of bearing enclose locking; Therefore oscillating bearing mounting process is launched to research, have great importance.
< < Chinese patent > > disclosed " a kind of roll riveting fixing device that assembles oscillating bearing " (201110083785.X), has disclosed and a kind of oscillating bearing has been fixed on to the frock in bearing saddle bore.This frock can realize oscillating bearing roll riveting flange, make it to be fixed on bearing race, but roll riveting wheel is hollow-core construction, and intensity is low, fragile.
Summary of the invention
In order to improve the intensity of rolling element, the utility model provides a kind of oscillating bearing roll riveting erecting device that three taper rollers are housed, and adopts three taper rollers to replace the roll riveting wheel of roll riveting fixing device.
The utility model solves the technical scheme that its technical problem adopts: a kind of oscillating bearing roll riveting erecting device that three taper rollers are housed, comprises taper roller, round nut I, round nut II, connecting flange, thrust ball bearing I, thrust ball bearing II and hexagon socket cap head screw.The top of the die inner ring of described device is Morse taper shank, and its lower surface is processed as tapered roller raceway; Three equally distributed cone tanks of bottom processing of die retainer, three taper rollers are arranged on respectively in the cavity of the cone tank formation bottom die inner ring lower surface tapered roller raceway and die retainer.Thrust ball bearing II, thrust ball bearing I, round nut I, the round nut II of described die inner ring lower end shoulder are axially fixed in connecting flange on die inner ring, and described die retainer connects with connecting flange by hexagon socket cap head screw.
The intersection point of the axis extended line of described three taper rollers is on the axis of roll riveting device.
The beneficial effects of the utility model are: adopt three taper roller roll extrusion oscillating bearing outer ring notches, because taper roller is solid, intensity is high, thereby has improved the service life of roll riveting erecting device.Meanwhile, this device dismounting, easy for installation, is convenient to timely convenient replacing taper roller, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the oscillating bearing roll riveting erecting device cutaway view that three taper rollers are housed;
Fig. 2 is die inner ring partial sectional view;
Fig. 3 is die retainer schematic diagram.
In above-mentioned accompanying drawing, 1. die inner ring, 2. round nut I, 3. round nut II, 4. thrust ball bearing I, 5. hexagon socket cap head screw, 6. connecting flange, 7. thrust ball bearing II, 8. die retainer, 9. taper roller.
The specific embodiment
Embodiment
During assembling, in the oscillating bearing roll riveting erecting device cutaway view that three taper rollers are housed shown in Fig. 1, first thrust ball bearing II is contained on the shoulder of die inner ring 1 bottom, afterwards, connecting flange 6, thrust ball bearing I4 are installed, then round nut I2, round nut II3 are screwed on the external screw thread of die inner ring 1 and screw.Three taper rollers 9 are placed in the cone tank of die retainer 8, then die retainer 8 is arranged on connecting flange 6, with 6 hexagon socket cap head screws 5, tighten.
The top Morse taper shank of die inner ring 1 connects with power set, die retainer 8 is the retainer of three taper rollers 9, and during device work, die inner ring 1 rotates, three taper rollers 9 are close to the rolling path rolling of die inner ring 1, and drive 8 rotations of die retainer.
During work, this device is fixed on to existing rotation to be had again on the power set of axially-movable, and the oscillating bearing of outer ring fluting is placed in seat ring and is fixed on together on workbench, makes it can not be axially and radial motion.The center of the oscillating bearing roll riveting erecting device that three taper rollers are housed is aimed at the center of oscillating bearing, by given rotating speed, feed speed and feeding displacement, carries out roll riveting operation.
Claims (2)
1. the oscillating bearing roll riveting erecting device that three taper rollers are housed, comprise taper roller (9), round nut I (2), round nut II (3), connecting flange (6), thrust ball bearing I (4), thrust ball bearing II (7) and hexagon socket cap head screw (5), it is characterized in that: the top of die inner ring (1) is Morse taper shank, and its lower surface is processed as tapered roller raceway; Three equally distributed cone tanks of bottom processing of die retainer (8), three taper rollers (9) are arranged on respectively in the cavity of the cone tank formation bottom die inner ring (1) lower surface tapered roller raceway and die retainer (8), thrust ball bearing II (7), the thrust ball bearing I (4) of described die inner ring (1) lower end shoulder, round nut I (2), round nut II (3) are axially fixed in die inner ring (1) above by connecting flange (6), and described die retainer (8) connects with connecting flange (6) by hexagon socket cap head screw (5).
2. the oscillating bearing roll riveting erecting device that three taper rollers are housed according to claim 1, is characterized in that: the intersection point of the axis extended line of three taper rollers (9) is on the axis of roll riveting device.
