Abstract
The utility model belongs to the technical field of rollers, and discloses a composite roller. The main technical features are that the composite roller comprises a central spindle with bearings, wherein a composite layer is arranged on the outer side of the central spindle. Therefore, under the condition that the diameter of the roller is not increased, the composite layer on the outer side of the central spindle can be very thick; during use, with the friction of the roller, the diameter of the roller is decreased slowly, the properties of the roller cannot be influenced, the wear resistance is high, and the service life is greatly prolonged. As a further improvement on the composite roller, fin strips are arranged on the periphery of the composite layer; the section shape of the fin strips is trapezoid, or a trapezoid-like shape of which the top end is an arc-shaped surface. Thus, materials are saved, the cost of the roller is reduced, the weight and rotating power of the roller are reduced, the energy waste is effectively reduced, the frictional force between the roller and a conveyer belt can also be increased, and the slipping between the roller and the conveyer belt is avoided.
Description
Technical field
The utility model belongs to cylinder technical field, relates to specifically composite material cylinder.
Background technology
In mine, the conveying place of the solid material such as colliery, chemical industry, great majority adopt and complete with the conveying machinery of cylinder.The cylinder using mostly at present is metal tub, and due to working environment humidity, it is acid or alkaline that environment is, and cylinder is easily corroded, and the wear resisting property of metal is poor, causes greatly reduce its service life.
In order to extend its service life, be enclosed with antifriction rubber layer in metal roller outside, although improved like this wear resisting property of metal roller, extend its service life, there is following defect in this cylinder: one, in use procedure, the easy local shedding of antifriction rubber layer causes part metals cylinder outside exposed, reduced the decay resistance of cylinder, and they are two years old, anti-corrosive rubber layer is thinner, and long-time wearing and tearing meeting wears away this anti-corrosive rubber layer.
Utility model content
The technical matters that the utility model solves is just to provide the composite material cylinder of a kind of corrosion resistance and good, long service life.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is: comprise the mandrel with bearing, have composite layer in the arranged outside of described mandrel.
Its additional technical feature is:
Be provided with fin bar at the periphery of described composite layer;
The cross sectional shape of described fin bar is trapezoidal;
The radial outer side in the cross section of described fin bar is circular-arc.
The composite material cylinder that the utility model provides, compared with the existing technology have the following advantages: one, due to the mandrel comprising with bearing, has composite layer in the arranged outside of described mandrel, like this, in the situation that not improving diameter of cylinder, the composite layer of mandrel can be very thick, in use, and along with the friction of cylinder, diameter of cylinder slowly diminishes, the performance that can not affect cylinder, wear resisting property is good, and greatly strengthen service life; They are two years old, owing to being provided with fin bar at the periphery of described composite layer, the cross sectional shape of described fin bar is trapezoidal, like this, save material, reduced cylinder cost, can reduce quality and the rotational power of cylinder, effectively reduce energy dissipation, can also increase the friction force between cylinder and load-transfer device, avoided skidding between cylinder and load-transfer device; Its three, because the radial outer side in the cross section of described fin bar is circular-arc, in course of conveying, between load-transfer device and cylinder, contact surface is large, has avoided the damage to load-transfer device, has extended the service life of load-transfer device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the longitudinal axial slices of composite material cylinder;
Fig. 2 is the structural representation of the longitudinal radial section of composite material cylinder;
Fig. 3 is the structural representation of the composite material cylinder of built-in bearing;
Fig. 4 is the structural representation with the longitudinal axial slices of composite material cylinder of fin bar;
Fig. 5 is the structural representation with the longitudinal radial section of composite material cylinder of fin bar;
Fig. 6 is the structural representation of the another kind of longitudinal radial section of composite material cylinder with fin bar.
The specific embodiment
The structure of composite material cylinder the utility model being proposed below in conjunction with the drawings and specific embodiments is described further.
As depicted in figs. 1 and 2, be the structural representation of composite material cylinder.Its structure comprises the mandrel 2 with bearing 1, has composite layer 3 in the arranged outside of mandrel 2.Like this, in the situation that not improving diameter of cylinder, the composite layer 3 of mandrel 2 can be very thick, and in use, along with the friction of cylinder, diameter of cylinder slowly diminishes, and can not affect the performance of cylinder, and wear resisting property is good, and greatly strengthen service life.As shown in Figure 3, bearing 1 can be also built-in bearing.
As shown in Figure 4 and Figure 5, be provided with fin bar 4 at the periphery of composite layer 3, the cross sectional shape of fin bar 4 is trapezoidal, like this, save material, reduced cylinder cost, can reduce quality and the rotational power of cylinder, effectively reduce energy dissipation, can also increase the friction force between cylinder and load-transfer device, avoided skidding between cylinder and load-transfer device.As shown in Figure 6, the radial outer side 41 in the cross section of fin bar 4 is circular-arc, and in course of conveying, between load-transfer device and cylinder, contact surface is large, has avoided the damage to load-transfer device, has extended the service life of load-transfer device.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the utility model composite material roller frame, just drops on the scope of the utility model protection.
