Further, the wheel bearing 2 that sidewinders includes side wheel 21, sidewinders wheel shaft 22 and side roller brackets 23, the side
Roller shaft 22 is fixedly connected on the side roller brackets 23, and the side wheel 21 is rotationally connected with described sidewinder on wheel shaft 22.
In 21 rotation process of side wheel, due to the presence of axial force, the side wheel 21 can and the side roller brackets 23 it
Between rub, and 23 hardness of the side roller brackets is softer, be easy to cause the friction of side roller brackets 23 failure, another party
Face, due to the presence of radial force, equipment such as 21 meeting of side wheel and fork truck and sidewindering rub between wheel shaft 22, therefore this
Application is provided with multiple holes or slot on the side wheel 21, is filled with solid lubricant 211 in the hole or slot.It is rubbing
Metal substrate assumes responsibility for most loads in the process.When the side wheel 21 and other component rub, in hole or slot
Solid lubricant 211 shift or invert to rubbing surface and move, form lubrication good, firm attachment on rubbing surface and uniformly cover
The solid transfer membrane of lid, considerably reduces fretting wear.With the progress of friction, the solid lubricant 211 of insertion is constantly mentioned
For rubbing surface, to the good lubrication of rubbing surface when ensure that longtime running, improve the composite track roller uses the longevity
Life.And in hole or slot add solid lubricant 211 method not will increase it is described sidewinder space shared by wheel bearing, more can
Adapt to small device.The features such as wheel bearing 2 that sidewinders is high with bearing capacity, impact resistance, high temperature resistant, self-lubricating capacities are strong,
Especially suitable for heavy duty, low speed, reciprocal or swing etc. is difficult to lubricate and formed the occasion of oil film, also punching not afraid of water and other acid solutions
Etch and wash away.
In a specific embodiment, as shown in Fig. 2, the side wheel 21 is axially and radially provided with multiple pass through
The hole worn, preferably multiple holes the side wheel 21 axially and radially on be uniformly arranged, in hole be filled with solid lubricant
211, solid lubricant film can be so formed on each face of side wheel 21, to the good of rubbing surface when ensure that longtime running
Good lubrication, improves the service life of the composite track roller.
Further, the main track roller 1 includes main roller 11 and main roller shaft 12, and the main roller 11 is arranged in institute
State the outside of main roller shaft 12, wherein main roller shaft 12 is the part connected as composite track roller with equipment, usual main rolling
The head of wheel shaft 12 is designed as chamfering, facilitates installation, and directly main roller shaft 12 can be welded in equipment, can also be by main roller shaft
12 are welded on connecting plate and equipment assembling on round-meshed connecting plate again.In a specific embodiment, the main rolling
Wheel 11 includes inner ring 111, outer ring 112, rolling element 113 and retainer 114, and rolling element 113 is distributed in interior by means of retainer 114
Between circle 111 and outer ring 112, the rolling element 113 is, for example, ball etc., between the inner ring 111 and the main roller shaft 12
To be fitted close, do not relatively rotate, the outer ring 112 is 111 turns of inner ring relatively described under the rolling of the rolling element 113
It is dynamic.
Further, one end of the main roller shaft 12 has hole, and the wheel bearing 2 that sidewinders is located in the hole,

Shape, the side roller brackets 23 can be just placed in the hole.The wheel bearing 2 that sidewinders is arranged in the main roller shaft
In 12 hole, so that the composite track roller is compact-sized, the volume of composite track roller is reduced, so that occupied space
It is smaller, and mounting structure is simplified, to reduce manufacturing cost, and installation and maintenance are easier to.Wherein, the side wheel
21 axial direction is vertical with the axial direction of the main roller 11, so that the rotation direction of the side wheel 21 and main roller 11
Rotation direction it is different, to realize the rotation of both direction.
Specifically, the main roller shaft 12 includes cylindrical ontology 121, and the main roller shaft 12 further includes stopper section
122, the stopper section 122 is located at the outside of the ontology 121, and is preferably integrally formed with the ontology 121.It is described multiple
Closing roller bearing further includes retaining ring 3, and the retaining ring 3 is for fixing position of the main roller 11 in the main roller shaft 12.
The retaining ring 3 and the stopper section 122 limit position of the main roller 11 in the main roller shaft 12 jointly.
Further, the composite track roller further includes protective sheet 4.The protective sheet 4 is located at the main roller shaft 12
Between 23 front opening slot of front opening slot and the side roller brackets, rises and keep the side roller brackets 23 in the main roller
The effect of position on axis 12 prevents the relative rotation for surveying rolling wheel support 23 and the main roller shaft 12.
Further, the composite track roller further includes adjustment structure, described sidewinders wheel bearing 2 described for adjusting
Position in main roller shaft 12, specifically, one end is cylindrical cavity in the main roller shaft 12, and the other end is to adjust screw hole,
Hole is connected to screw hole is adjusted, and is provided in the adjusting screw hole and is adjusted screw 5, the adjusting screw 5 and the side wheel branch
Frame 23 abuts against, by adjusting the position for adjusting screw 5 in the adjusting screw hole, to sidewinder wheel bearing described in adjusting
2 position on the axial direction in the main roller shaft 12, and then can adjust and described sidewinder the equipment such as wheel bearing 2 and fork truck
Sideshake.Further, the composite track roller further includes stop portion 6, and the stop portion 6 is used for the adjusting spiral shell
Nail 5 is locked, and the stability of the sideshake of the equipment such as wheel bearing 2 and fork truck is sidewindered described in guarantee.In a specific embodiment
In, the stop portion 6 is retaining sheet, and the retaining sheet includes circular portion and These strip-shaped sections, the circular portion and the item
Shape part is integrally formed, and the adjusting screw hole is provided with strip groove, should be by the retaining sheet in circle when placing the retaining sheet
Shape part and the junction of These strip-shaped sections carry out bending, so that the circular portion and the These strip-shaped sections are vertical, then by institute
