Abstract
The present invention relates to a rolling bearing for supporting the rotation of a fish torpedo type tank body of an iron-mixing vehicle and load bearing, which is composed of a bearing seat, trunnions, an inner sleeve, an outer sleeve, rolling bodies and an oil cup, wherein the rolling bearing is arranged on the trunnions at both ends of a tank body of an iron-mixing vehicle; the outer sleeve is divided into an upper half sleeve and a lower half sleeve, and the lower half sleeve is inlaid in the bearing seat; the rolling bodies form a cylindrical shape, both ends of the cylindrical rolling bodies are respectively provided with a section of small cylinder, the rolling bodies are arranged between the trunnions and the outer sleeve, and a gap is arranged between the rolling bodies; the side face of the bearing seat is provided with an anti-thrust end face sliding bearing whose outer edge is provided with a groove, and an O-shaped sealing ring is arranged in the groove. The present invention has the advantages that because no holding frame is arranged between the rolling bodies, the rolling bodies are farthest placed so that the load bearing performance of the rolling bearing is effectively strengthened, and the service life of the rolling bearing is extended.
Description
Technical field
The invention belongs to axial antifriction bearing, particularly a kind of support torpedo type mixed iron car tank body rotation and load-bearing rolling bearing.
Background technology
Supporting rotation of torpedo type mixed iron car tank body and load-bearing bearing is one of vitals of metal mixer car, and nationality is to connect the principal and subordinate moved end by tank body.At present, the bearing that supports mixed iron flask body rotation of torpedo and load-bearing adopts sliding surface bearing mostly, mainly is made up of bearing housing and bearing support, and tank body rotates and is actually Frictional Slipping between gudgeon and the bearing housing.The problem of this bearing is: friction is sliding friction between axle and the bearing, and frictional coefficient is big, lubricated difficulty (oil most likely).
Summary of the invention
The objective of the invention is to avoid the deficiency on the above-mentioned prior art, provide that a kind of to have supporting capacity big, safe and reliable to operation, the transmission efficiency height, long service life, the support torpedo that maintains easily mixes rotation of iron flask body car and load-bearing rolling bearing.
According to support torpedo type mixed iron car tank body rotation of the present invention and load-bearing rolling bearing, by bearing support, gudgeon, interior overcoat and rolling body, oil duct is formed, it is characterized in that this bearing is arranged on the gudgeon at metal mixer car tank body two ends, its gudgeon is directly as the interior cover of rolling bearing, overcoat is divided into first cover and second cover, first cover is the bearing support loam cake, second cover is embedded in the bearing support, described rolling body is cylindrical, respectively be provided with one section small cylinder at cylindrical rolling body two ends, its rolling body is arranged between gudgeon and the overcoat, be provided with the gap between each rolling body, in the bearing support side Thrust Faces sliding surface bearing is housed, described Thrust Faces sliding surface bearing outer rim is provided with groove, and in groove " O " RunddichtringO is set.
According to support torpedo type mixed iron car tank body rotation of the present invention and load-bearing rolling bearing, described Thrust Faces sliding surface bearing is the convex-concave structure body, be installed on the small cylinder and bearing base at rolling body two ends, and by screw retention.
According to support metal mixer car tank body rotation of the present invention and load-bearing rolling bearing, described Thrust Faces sliding surface bearing outer rim groove is " trapezoidal " groove.
Because the present invention has adopted said structure, compared with prior art, the present invention has following advantage:
1, supporting capacity is big, and the transmission efficiency height is safe and reliable to operation.Owing to do not have retainer between the rolling body of the present invention, and so can place rolling body to greatest extent, when not changing bearing physical dimension, can strengthen its supporting capacity effectively, the setting of Thrust Faces sliding surface bearing, the axial motion that has stoped rolling body effectively becomes rolling resistance by traditional slip when making the tank body rotation, has improved transmission efficiency.
2, installation, maintenance is convenient, long service life.Because overcoat has adopted split type structure, have to make and install simply, maintenance is changed convenient; The present invention has adopted end-face seal ring in addition, therefore, having guaranteed that gudgeon bead and bearing face are lubricated, also guarantees the lubricated of rolling bearing rolling body simultaneously, has prolonged the work-ing life of bearing.。
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is a side-view of the present invention.
Accompanying drawing 3 is the upward view of bearing base of the present invention.
Accompanying drawing 4 is the enlarged view of Fig. 2 I of the present invention portion.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
Referring to accompanying drawing 1,2, support torpedo type mixed iron car tank body rotation of the present invention and load-bearing rolling bearing are made up of bearing support 7, gudgeon 8, interior overcoat and rolling body 5, lubricating cup 4, this bearing totally is four stud shaft bearings, see accompanying drawing 3, gudgeon 8 is arranged on the metal mixer car tank body two ends, its gudgeon 8 direct interior covers as rolling bearing; Overcoat of the present invention is divided into first cover 1 and second cover 6, is split type structure, and first cover 1 is the bearing support loam cake, and second cover 6 is embedded in the bearing support 7, has made things convenient for the installation and the maintenance of bearing.
For guaranteeing the safe operation of bearing, the present invention is equipped with Thrust Faces sliding surface bearing 2 in the bearing support side, and referring to accompanying drawing 4, described Thrust Faces sliding surface bearing 2 is the convex-concave structure body, be installed on the small cylinder 10 and bearing base 7 at rolling body 5 two ends, and fixing by screw 9.The small cylinder 10 at rolling body 5 two ends withstands the medial surface of Thrust Faces sliding surface bearing 2, its small cylinder 10 is used for guiding and installs and use, 5 of rolling bodys are movable between the boss of Thrust Faces sliding surface bearing 2 like this, therefore, prevented the axial motion of rolling body 5 effectively, guaranteed that rolling body 5 is all the time reliably around its raceway rotation.
The outer rim of Thrust Faces sliding surface bearing 2 of the present invention also is provided with groove, its groove is " trapezoidal " groove, and " O " RunddichtringO 3 is set in groove, " trapezoidal " groove can make sealing-ring 3 clamp within it, and difficult drop-off, the effect of sealing-ring 3 is that maintenance lubricating grease does not leak and prevents that dust from entering bearing inside, can guarantee that bearing runs well as long as regularly in bearing, fill grease like this, not only help improving the lubricating condition of roller, guarantee that gudgeon bead and bearing face are lubricated, also guarantee simultaneously the lubricated of rolling bearing rolling body, the work-ing life of improving bearing.
Compare with rolling bearing with tank body rotation of routine support torpedo type mixed iron car and load-bearing, this rolling bearing can improve supporting capacity and transmission efficiency, uses safer, reliable.
