Background

Lubricating oil is required to be regularly filled into the common composite sleeve or copper sleeve in the using and running process, so that the maintenance cost is increased; the shaft and the sleeve are easy to wear and have short service life in the operation process; the weight is heavy and the price is higher than that of the polymer composite bushing.

Through the retrieval, patent publication number is CN215805765U, discloses a composite bushing with anti-deformation function, including first welt, second welt and interior welt, the inside paste of first welt is connected with the second welt, and pastes at the both ends of second welt and be connected with the holding ring, the inside of second welt rotates and is connected with the interior welt, and the internal connection of interior welt has the ball. This composite bushing with anti-deformation function, the support bar of accessible trapezium structure supports the reinforcement to first welt and second welt, make this composite bushing can not take place to warp when the work is used, thereby reduce the fault rate that produces when composite bushing uses, be favorable to improving the work efficiency of this composite bushing of installation, ball through the inside even block of welt, make the welt more efficient at the rotation of second welt, can improve this composite bushing's lubricity, thereby reduce the wearing and tearing to installing this composite bushing apparatus, be favorable to this composite bushing's long-term use, among the prior art CN215805765U, although in use can be through the ball of the inside even block of welt, make the welt more efficient at the rotation of second welt, can improve this composite bushing's lubricity, thereby reduce the wearing and tearing to installing this composite bushing apparatus, but the defect that exists is: the existing composite bushing needs to be filled with lubricating oil regularly in the use and operation process, maintenance cost is increased, abrasion is easy to occur between a shaft and the bushing in the operation process, and the service life is short.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the problem that exists among the background art, propose a compound bush that single-point hung.

The technical scheme of the utility model: the utility model provides a compound bush that single-point hung, includes outer lane, roller, holder and solid lubricant, the inside solid lubricant that is provided with of outer lane, the solid lubricant both sides are provided with the recess, the inside holder that is provided with of recess, the inside roller that is the ring array and distributes that is provided with of holder, the radius of roller is less than solid lubricant's thickness.

During the compound bush that a single-point hung in this scheme of use, install the outer wall at the pivot with the outer lane, the pivot can take place sliding friction with solid lubricant in the pivoted, and solid lubricant can dissolve partly after the friction, forms emollient and guarantees that the pivoted in-process has lubricated effect, when solid lubricant wearing and tearing consume totally, its thickness can the step-down, and the pivot can contact with the roller this moment, avoids direct and outer lane inner wall contact, causes violent wearing and tearing.

Preferably, the retainer is internally provided with mounting grooves distributed in an annular array, and the rollers are mounted in the mounting grooves. The mounting slots can provide mounting locations for the rollers.

Preferably, a positioning shaft is inserted into the roller, and the positioning shaft is fixedly connected with the inner wall of the mounting groove. Can make the roller can be when solid lubricant wearing and tearing to a certain extent through the setting of location axle, roller and the contact of pivot outer wall, village cover in the past does not have this structure, and when solid lubricant consumed almost, the pivot can with outer lane direct friction, cause wearing and tearing, consequently with the roller setting here, can change sliding wear into rolling wear, reduce the wearing and tearing to the pivot.

Preferably, a rotating shaft is arranged in the outer ring, and the outer wall of the rotating shaft is attached to the solid lubricant. The outer ring can be attached to the rotating shaft through the solid lubricant, so that the solid lubricant can provide a lubricating effect when rotating, a large amount of lubricant is reduced, and the running stability is ensured.

Compared with the prior art, the utility model discloses following profitable technological effect has:

1. the oil-free self-lubricating oil is maintenance-free and self-lubricating, and can be used under the condition of no oil or less oil;

2. the solid lubricant can reduce the abrasion of the outer wall of the rotating shaft by using the roller after being consumed.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the utility model provides a compound bush that single-point hung, including outer lane 1, roller 2, holder 3 and solid lubricant 5, the inside solid lubricant 5 that is provided with of outer lane 1, the inside pivot 8 that is provided with of outer lane 1, 8 outer walls of pivot and the laminating of solid lubricant 5, setting up through solid lubricant 5 can make outer lane 1 and the laminating of pivot 8, when rotating, solid lubricant 5 can provide lubricated effect, reduce a large amount of interpolation of lubricant, and guarantee the steady operation, solid lubricant 5 both sides are provided with recess 4, the inside holder 3 that is provided with of recess 4, the inside roller 2 that is the distribution of annular array that is provided with of holder 3, the inside mounting groove 7 that is the distribution of annular array that is provided with of holder 3, roller 2 installs inside mounting groove 7, can provide the mounted position for roller 2 through mounting groove 7, the inside location axle 6 of pegging graft of roller 2, location axle 6 and mounting groove 7 inner wall fixed connection, can make roller 2 can be when solid lubricant 5 weares to the certain degree through the setting of location axle 6, roller 2 and pivot 8 outer wall contact, there is not the solid lubricant cover in the past, the many cunning wear of lubricant 5, the wearing and tearing that the slide, therefore the outer lane can not be less than the direct wear of roller wear and wear of the roller, the wear of the rolling radius that the rolling, the rolling radius that the roller 2 that will cause here, the wear and wear of the rolling, the rolling radius that the rolling is less than the wear of roller, the wear of the rolling.

In this embodiment, install outer lane 1 at the outer wall of pivot 8, pivot 8 can take place sliding friction with solid lubricant 5 when the pivoted, and solid lubricant 5 can dissolve partly after the friction, forms the lubricated effect that has in-process of emollient assurance pivoted, when solid lubricant 5 wearing and tearing consume totally, its thickness can become low, and pivot 8 can contact with roller 2 this moment, avoids direct and the contact of 1 inner wall in outer lane, causes violent wearing and tearing.

The above embodiments are merely some preferred embodiments of the present invention, and those skilled in the art can make various alternative modifications and combinations to the above embodiments based on the technical solution of the present invention and the related teachings of the above embodiments.
