Abstract
The utility model relates to a castor which is formed by that a circular rotary ball is embedded in a supporting seat with an upper part in circular shape or other any shape and a lower part in super-semicircular. Since the rotating shaft and the bearing of the existing castor used for support and rotation are omitted, the castor can rotate with high sensitivity, and the disadvantage of difficult distortion of the existing castor is avoided. The castor exceeds the existing castor in production process, the adoption of raw materials and cost, and the castor has wide value in use and favorable economic benefit.
Description
The present invention is a kind of novel universal wheel.
Existing cardan wheel generally all is by a bearing, and the double-decker of a rotating shaft and a wheel (or changeing ball) combines.Owing to be that double-deck rotating part forms, when several wheels are fixed on the same object, when rotating to either party, because each is taken turns and adjusts simultaneously direction, each takes turns unbalance stress, direction can occur and adjust inconsistent and the shortcomings such as dumb and distortion effort that cause.Its production technology is also comparatively complicated and cost is higher.
The objective of the invention is to create a kind of rotation flexibly, production technology is simple, cost is lower.Broad-spectrum New-type universal castor.
Technical spirit of the present invention, realize by following technical process:
1. make that top is rounded, square or other shape arbitrarily, the bottom is super semi-round footstock.
2. make a ball.
3. ball is installed in the super semicircle footstock.(referring to Figure of description) this figure is installation diagram.
4. because the bottom diameter of super semicircle footstock is littler than ball diameter, when assembling, installs into and can realize with the rising-heat contracting-cold method.
The present invention has saved the complicated level of existing universal wheel, only gets final product with the semicircle footstock of the ball peace excess of imports.Not only rotate flexibly, and several wheel is fixed on the same object.When rotating simultaneously, the dumb problem of the inconsistent effort that causes of rotation direction of also having avoided each wheel to cause because adjusting simultaneously direction.
The present invention is needed raw material in producing enforcement, can use nonmetallic materials, such as various industrial plastics such as Maranyls (nylon).These materials have self lubricity and antisoiling function, its stable chemical performance, and intensity can reach requirement, so be very suitable easy non-metallic material.
The present invention can be according to market and consumption person's needs in the production implementation process, the production plurality of specifications, and turning to bulb diameter can be 5, and---between 300 millimeters, wherein take diameter as 10---100 millimeters are the most commonly used.
Claims (3)
1, a kind of New-type universal castor is characterized in that a circle is turned to ball, is installed in a top and is positive square or circle, and the bottom is in the super semicircular footstock.
2,, it is characterized in that available Maranyl (nylon) makes according to the 1. described novel universal of claim wheel.
3, according to claim 1., 2. described novel universal wheel, it is characterized in that changeing ball diameter 5---between 300 millimeters.
