Abstract
The utility model relates to a universal wheel which is used on the goods delivery van, the medical equipment, the furniture and the household appliance. The universal wheel is mainly composed of a rolling ball, a shell, a roller, a guide connecting sleeve, a connecting screw rod, etc. A roller steel bowl is arranged above the roller, and the inner surface of the steel bowl is provided with a spherical surface groove for placing the roller. A rubber bowl is arranged between the steel bowl and the shell, and the inner surface of the rubber bowl is provided with a strong slot. The vibration and the noise are reduced when the universal wheel is rotated, and the roller ball can not be dead pressed under the larger born pressure, because the rolling ball and the roller are not directly contacted with the shell, and the rubber bowl is provided. Additionally, the utility model has the advantages of simple structure, flexible rotation, etc.
Description
The utility model relates to a kind of cardan wheel that is used on article carrying car, medical facilities, the roving furniture of need and the household electrical appliance etc.
At present, its spin of the cardan wheel of Xiao Shouing and shell direct contact produce very big noise on the market, and vibration is bigger, and when too big, spin kills easily as pressure.The CN2031771U patent disclosure a kind of spherical universal castor, on a horizontal circumference of shell inner surface, there are several to place the spherical groove of ball, spheroid can be rotated to any direction neatly, but because metal balls and metal case direct contact, so can't solve noise and the big problem of vibration.
The purpose of this utility model is to overcome the existing deficiency of above-mentioned cardan wheel, provides a kind of noise little, vibrates for a short time, simple in structure, rotates cardan wheel flexibly.
Task of the present utility model realizes in the following manner: cardan wheel mainly is made up of parts such as spin, shell, ball, guiding adapter sleeve, connecting screw rod and coupling nuts, above spin, be provided with the steel bowl, evenly be provided with 3～8 spherical grooves of placing ball on the horizontal circumference of steel bowl inside face, the central horizontal face folder α angle of groove and ball, the α angle is 35～55 °, and the rubber bowl that has vibration damping and reduce function of noise is housed between steel bowl and the shell.
For the contact point between ball and the spin is increased, bearing surface increases, thereby it is more flexible that cardan wheel is rotated, on two varying level circumference of ball and steel bowl inside face, evenly be provided with 3～6 spherical grooves of placing ball respectively, the central horizontal face of groove and spin presss from both sides a α angle, and the α angle is 35～55 °.
In order to increase the elasticity of rubber bowl, on the inside face of rubber bowl, evenly be provided with 4～8 powerful grooves.
Spheroid can be made with materials such as bakelite, pottery, glass.
Vibrationproof low-noise universal wheel of the present utility model is because ball and spin are all not direct and housing contacts, and between steel bowl and shell, had additional rubber bowl, make vibration and noise lower greatly, it is more steady that transport trolley and household electrical appliance are moved, and bearing under the bigger pressure, ball can not be crushed to death yet.In addition, the utility model also has rotation flexibly, advantage simple in structure, easy to manufacture, cheap.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is the view of the utility model A-A cross-sectional plane;
Fig. 2 is a longitudinal construction scheme drawing of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Embodiment:
With reference to Fig. 1, Fig. 2, vibrationproof low-noise universal wheel is by spin 1, metal case 2, ball 3, guiding adapter sleeve 5, parts such as connecting screw rod 6 and coupling nut 8 are formed, bearing quality steel bowl 10 is housed above spin 1, evenly be processed with 3 spherical grooves 7 of placing ball on two different horizontal circumference of steel bowl 10 inside faces respectively, spherical groove 7 on the same horizontal circumference is the folder hexagonal angle mutually, spherical groove 7 symmetries on two horizontal circumference are staggeredly arranged, spherical groove 7 on one of them horizontal circumference is 40 ° with the angle of spin 1 central horizontal face, spherical groove 7 on another horizontal circumference is 50 ° with the angle of spin 1 central horizontal face, between steel bowl 10 and shell 2, rubber bowl 4 is housed, evenly is provided with 6 powerful grooves 9 on the inside face of rubber bowl 4.
Claims (3)
