Abstract
The utility model discloses a universal wheel. The universal wheel is capable of preventing deformation, caused by large load, of a pin shaft, and is long in service life. The universal wheel comprises an upper connecting plate and a lower connecting plate, wherein bearings are installed between the upper connecting plate and the lower connecting plate through first bearing frames and second bearing frames, the second bearing frames are connected with the lower connecting plates through bolts and nuts, a main support is installed on the lower connecting plate, the pin shaft is installed on the main support, two sets of idler wheels are installed on the pin shaft, a supporting frame is connected to the pin shaft between the two sets of idler wheels in a rotating mode, and the supporting frame is fixedly connected with the lower connecting plate. According to the universal wheel, due to the fact that the supporting frame is installed on the lower connecting plate between the two sets of idler wheels, pressure borne by the pin shaft can be relieved, then deformation, caused by the large load, of the pin shaft is avoided, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of cardan wheel.
Background technology
Cardan wheel is mounted in a kind of annex moved of being convenient on object bottom or leg.
At present, cardan wheel on main equipment comprises upper junction plate, lower connecting plate, between upper junction plate and lower connecting plate, by two bearing frames and bolt, bearing is installed, and bracing frame is installed on lower connecting plate, bearing pin is installed on bracing frame, two groups of rollers are installed on bearing pin.The weight of carrying due to main equipment is larger, usually causes bearing pin to produce distortion, affects the service life of cardan wheel.
The utility model content
The purpose of this utility model is for the technological deficiency existed in prior art, and a kind of bearing pin distortion caused greatly due to load that can prevent is provided, and improves the cardan wheel in service life.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of cardan wheel, comprise upper junction plate, lower connecting plate, it is characterized in that, by clutch shaft bearing frame and the second bearing frame, bearing is installed between described upper junction plate and lower connecting plate, described the second bearing frame is connected with described lower connecting plate by screw bolt and nut, on described lower connecting plate, main support is installed, on described main support, bearing pin is installed, two groups of rollers are installed on described bearing pin, the bracing frame that has been rotatably connected on bearing pin between described two groups of rollers, support frame as described above is fixedly connected with described lower connecting plate.
Described bearing is pressure bearing.
Compared with prior art, the beneficial effects of the utility model are:
1, on the lower connecting plate between two groups of rollers, bracing frame is installed in cardan wheel of the present utility model, can alleviates the pressure that bearing pin bears, thereby avoid the distortion caused greatly due to load, improved service life.
2, change common ball-bearing casing into pressure bearing in cardan wheel of the present utility model, can increase bearing capacity, improved the service life of cardan wheel.
The accompanying drawing explanation
Figure 1 shows that the front view of the utility model cardan wheel;
Figure 2 shows that the lateral plan of the utility model cardan wheel.
In figure: 1. upper junction plate, 2. clutch shaft bearing frame, 3. the second bearing frame, 4. nut, 5. bearing, 6. bracing frame, 7. lower connecting plate, 8. bolt, 9. main support, 10. roller, 11. bearing pins.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model cardan wheel as shown in Figure 1 and Figure 2, comprise upper junction plate 1, lower connecting plate 7, by clutch shaft bearing frame 2 and the second bearing frame 3, bearing 5 is installed between described upper junction plate 1 and lower connecting plate 7, in cardan wheel of the present utility model, bearing 5 selection pressure bearings.Described the second bearing frame 3 is connected with described lower connecting plate 7 with nut 4 by bolt 8, on described lower connecting plate 7, main support 9 is installed, on described main support 9, bearing pin 11 is installed, two groups of rollers 10 are installed on described bearing pin 11, the bracing frame 6 that has been rotatably connected on bearing pin 11 between described two groups of rollers 10, support frame as described above 6 is fixedly connected with described lower connecting plate 7.
During use, pressure bearing 5 drives lower connecting plates 7, thus drive bearing pin 11 and on two groups of rollers 10 rotate, realize universal the turning in the horizontal surface of object.Due to the supporting role of bracing frame 6, can reduce the application force of load to bearing pin 11, can avoid bearing pin due to the distortion that load causes greatly, improved service life.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a cardan wheel, comprise upper junction plate, lower connecting plate, it is characterized in that, by clutch shaft bearing frame and the second bearing frame, bearing is installed between described upper junction plate and lower connecting plate, described the second bearing frame is connected with described lower connecting plate by screw bolt and nut, on described lower connecting plate, main support is installed, on described main support, bearing pin is installed, two groups of rollers are installed on described bearing pin, the bracing frame that has been rotatably connected on bearing pin between described two groups of rollers, support frame as described above is fixedly connected with described lower connecting plate.
