Abstract
The invention discloses a double-row spherical roller bearing with a T-shaped locking device, comprising the inner ring of the bearing, the outer ring of the bearing and two rows of rollers, wherein a shroud extends out of one side of the inner ring of the bearing; the inner wall corresponding to the shroud, of the section of the inner ring is provided with a plurality of slots; the outer wall of the shroud is provided with a locking ring with an opening; and the opening of the locking ring is provided with an opening locking structure capable of drawing and locking the opening. Because the roller bearing is disassembled and assembled by clamping or loosening the inner ring of the bearing through the locking device arranged on the inner ring of the bearing, the roller bearing is convenient to install, disassemble and assemble and has even and reliable locking force to ensure concentricity and reliability for installing the roller bearing so as to improve rotation precision. The double-row spherical roller bearing is suitable for long-axis intermediate support under heavy load and application occasions which have rigorous conditions and always need to be replaced and maintained, such as outdoor dustiness, wateriness, much pollution and the like.
Description
[technical field]
The present invention relates to a kind of biserial spheric roller bearing.
[background technique]
The biserial spheric roller bearing has the advantage of bearing load than big and long service life as one of miscellaneous bearing type, is used for the bearing support of heavier load more.When using at present, the normal interference fit that adopts is installed in the biserial spheric roller bearing on axle (or pointed journal), adapter sleeve or the withdrawal sleeve, though can obtain higher installation coaxality and bearing running accuracy, but installation and removal difficulty, often need the application of changing, keeping in repair for major axis intermediate support and outdoor application, operate very loaded down with trivial details, maintenance cost height, even undermine mutual cooperation or peripheral part.The technology of the present invention is a kind ofly than the long bearing inner ring and at extended end the biserial spheric roller bearing of locking device to be set, and has realized that bearing is with axle reliable fit, easy dismounting and have high coaxality and the running accuracy of installing.
[summary of the invention]
The present invention overcomes the deficiencies in the prior art, provides a kind of and bears heavy duty, reliable lock, easy to loading and unloading, installation coaxality height, thereby obtain the biserial spheric roller bearing of the band T type locking device of high running accuracy.
In order to solve the technical problem of above-mentioned existence, the present invention takes following technical proposals:
A kind of biserial spheric roller bearing with T type locking device includes inside and outside circle of bearing and two row rollers, stretches out a convex shoulder in bearing inner race one side, is provided with several short slots on the inwall of pairing that section inner ring of this convex shoulder; On this convex shoulder outer wall, be provided with the locking ring of a band opening, be provided with the hatch lock locking structure that this opening can be drawn over to one's side locking at the opening of this locking ring.
In improvement project to the biserial spheric roller bearing of above-mentioned band T type locking device, described hatch lock locking structure is a Cock screw, described locking ring has the perforation of inserting for Cock screw and is complementary with the screw thread of Cock screw in the opening both sides tapped hole.
In the improvement project to the biserial spheric roller bearing of above-mentioned band T type locking device, described locking ring is being provided with groove on the inwall of this opening.
Compared with prior art, the present invention has following advantage: because it is the chucking by being arranged on the locking device on the bearing inner race or unclamps bearing inner race and come the dismounting roller bearing, this not only mounts and dismounts conveniently, and coupling mechanism force is evenly reliable, can guarantee coaxality and reliability that roller bearing is installed, thereby the raising running accuracy, its be applicable to heavy duty down the major axis intermediate support and outdoor many dirt, Duo Shui, how condition harshness such as pollutions, often need the application of changing, keeping in repair.
The present invention is further described below in conjunction with the drawings and specific embodiments:
[description of drawings]
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the right elevation of Fig. 1.
[embodiment]
The present invention is a kind of biserial spheric roller bearing with T type locking device, as shown in Figure 1, 2, include inside and outside circle 1,2 of bearing and two row rollers 3, stretch out a convex shoulder 11, on the inwall of these convex shoulder 11 pairing that section inner rings, be provided with several parallel short slots 12 in bearing inner race 1 one sides; On these convex shoulder 11 outer walls, be provided with the locking ring 4 of a band opening 41, be provided with the hatch lock locking structure 5 that this opening can be drawn over to one's side locking at opening 41 places of this locking ring 4, hatch lock locking structure 5 and locking ring 4 have constituted T type locking device, like this when being installed to the present invention on the axle, locking that just can be by hatch lock locking structure 5 is clamped on the inwall of the bearing inner race at short slot 12 places on the axle, thereby realizes the installation of biserial spheric roller bearing; When dismounting, unclamping the hatch lock locking structure gets final product, as can be seen, the present invention is by the chucking that is arranged on the locking device on the bearing inner race or unclamps bearing inner race and come the dismounting roller bearing, this is not only easy to loading and unloading, and coupling mechanism force is evenly reliable, can guarantee coaxality and reliability that roller bearing is installed, thereby the raising running accuracy, its be applicable to heavy duty down the major axis intermediate support and outdoor many dirt, Duo Shui, how condition harshness such as pollutions, often need the application of changing, keeping in repair.The effect of short slot 12 is to make the pressurized contraction deformation under the effect of locking device of the inner ring at this place, thereby makes bearing locking on axle.
In the present embodiment, described hatch lock locking structure 5 is a Cock screw, described locking ring 4 has the perforation 42 of inserting for Cock screw and is complementary with the screw thread of Cock screw in opening 41 both sides tapped hole 43.
In the present embodiment, as shown in Figure 2, described locking ring 4 is being provided with at least one groove 44 on the inwall of this opening 41, can make the clamping of locking device like this and unclamp more flexible.
