Abstract
The invention relates to a self-aligning roller bearing with sealing and installation holes. The self-aligning roller bearing comprises an outer ring (1), an inner ring (2), two rows of spherical rollers (3) and a holding frame (4). The self-aligning roller bearing is characterized in that the installation holes are formed in the axial direction of the end faces of the outer ring (1) and the inner ring (2); an oil cup lubricating channel is formed in the outer ring (1) and is detachably provided with a stopper; the self-aligning roller bearing further comprises a sealing bearing which is composed of an outer sealing support (7) and an inner sealing support (5). The outer sealing support (7) and the inner sealing support (5) are connected with the outer ring (1) and the inner ring (2) through fasteners (9) respectively. It is proved through tests that the requirement for supporting of a petroleum drilling machine winch can be better met, and the self-aligning roller bearing has the beneficial effects of being high in load, long in service life and high in reliability.
Description
Technical field
The present invention relates to a kind of with sealing and the selfaligning roller bearing of mounting hole.
Background technique
The turntable bearing of existing band mounting hole adopts single double four-point contact ball pivoting support usually, double row reducing ball pivoting support, spin combines pivoting support with roller, and double tapered roller pivoting support, three-row roller pivoting support etc., mainly bear axial force and tilting moment.Its shortcoming is as follows: it is little to bear radial ability; After installing, aligning performance is poor.And existing selfaligning roller bearing, usually by bearing bore diameter and axle interference or transition fit, external diameter coordinates with bearing support and realizes bearing and install, without mounting hole; The sealing of bearing is usually on housing; Its shortcoming is as follows: to application circumstances, bearing bad adaptability; Sealing is added on bearing support housing, designs compact not.
Summary of the invention
The object of this invention is to provide a kind of high load, long lifetime, the band sealing of high reliability and the selfaligning roller bearing of mounting hole, can be too thick or housing assembling is complicated and reliably use under mainly bearing the occasion of radial force at axle.
With sealing and the selfaligning roller bearing of mounting hole, comprise outer ring, inner ring, two row spherical roller and retainers, its specialization is: all have mounting hole in the end face axial of described outer ring and inner ring; This outer ring has cascade oiling passage, and detachably stopper is installed on this cascade oiling is logical; Also comprise sealing supporting, sealing supporting is supported by external sealed and interior sealing support forms, and the support of this external sealed supports with interior sealing and is connected with aforesaid outer ring and inner ring respectively by fastening piece.
The end face axial wherein supported at external sealed has mounting hole, is provided with radial location step on this mounting hole side, is provided with seal groove, is provided with the first seal ring in sealing groove on this radial location step side.
The end face axial wherein supported in interior sealing has mounting hole, is provided with radial location step on this mounting hole side, is provided with seal groove, is provided with the second seal ring in sealing groove on this radial location step side.
Bearing of the present invention improves on prior art basis, and at its outer ring and inner ring all with can with the through hole of bolt connection or tapped hole, retainer be integral cage, and band lubrication channel, carries the pivoting support of sealing.And be specially adapted to following situations: 1. restricted to installation conditions, namely axle is too thick or housing assembling is complicated, mainly bears the occasion of radial force; 2. bearing is to the occasion of installing tilt sensitive; 3. bearing working in the wild, occasion difficult in maintenance; 4. requirement is had to bearing life, consistent with this equipment overhaul cycle, be generally more than 3 years.Through probationary certificate, oil-well rig winch can be met better and support needs, there is the effect of high load, long lifetime, high reliability.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of with sealing and the selfaligning roller bearing of mounting hole, comprise outer ring 1, inner ring 2, two row spherical roller 3 and retainer 4, mounting hole (through hole or tapped hole) is all drilled with in the end face axial of described outer ring 1 and inner ring 2, by bolt, outer ring 1 (or inner ring 2) and shell flange (or axle) can be coupled together, make host design compact structure, safeguard easily.This outer ring 1 has cascade oiling passage, and detachably stopper is installed on this cascade oiling is logical.Also comprise sealing supporting, the two ends of sealing supporting are connected with aforesaid outer ring 1 and inner ring 2 respectively by fastening piece 9, and are equipped with sealing configuration in joint.
Embodiment 1:
Wherein seal the structure of supporting as shown in Figure 1, according to the reliability of sealing, the end face can fitted at sealing supporting and inner ring 2 (or outer ring 1) designs sealing configuration, sealing supporting is Hardened And Tempered Steel, end face can offer seal groove, such as O shape ring recess, is provided with O shape circle as seal ring in this O shape ring recess.
Further, improvements of the present invention are as follows:
1. Internal and external cycle 1 is with mounting hole (through hole or tapped hole), and wherein cascade oiling passage is with in outer ring 1;
2. roller 3 is dribbled the spherical roller 3 of basal plane, and retainer 4 is two half CD type retainers 4;
3. arrange separately sealing supporting, sealing (installation) groove is opened in sealing supporting, and end face can offer O shape ring recess;
Using method of the present invention is:
As shown in Figure 1, during assembling, first retainer 4 and part roller 3 are enclosed within inner ring 2, then inner ring 2 assembly, utilize aligning function to be loaded on outer ring 1, then fill remaining roller 3 by filling slot.In O shape circle is loaded, external sealed supports in the shape ring recess of O, and the positioning step supported by interior external sealed, is connected as one sealing supporting with socket head screw with outer ring 1 (or inner ring 2); Seal ring sealing is supported in seal groove, seal lip is overlapped in ring face again.
Claims (3)
1. one kind with sealing and the selfaligning roller bearing of mounting hole, comprise outer ring (1), inner ring (2), two row spherical rollers (3) and retainer (4), it is characterized in that: all have mounting hole in the end face axial of described outer ring (1) and inner ring (2); This outer ring (1) has cascade oiling passage, and detachably stopper is installed on this cascade oiling is logical; Also comprise sealing supporting, sealing supporting supports (7) by external sealed and interior sealing support (5) forms, and this external sealed support (7) supports (5) with interior sealing and is connected with aforesaid outer ring (1) and inner ring (2) respectively by fastening piece (9).
