Abstract
The utility model belongs to the technical field of the universal wheel, especially, the super -silent universal wheel who relates to a simple structure, convenient assembling. A super -silent universal wheel which characterized in that: include wheel hub and the rim of forming by a plurality of gyro wheels, wheel hub is assembled and is constituteed by outside wheel hub, middle wheel hub, inboard wheel hub, the gyro wheel is dolioform, the rim department of wheel hub both sides face evenly is equipped with the recess that a plurality of and dolioform gyro wheel matches, the recess of outside wheel hub side sets up with the recess of inboard wheel hub side is crisscross, be equipped with the shaft hole on two cell walls of outside wheel hub and inboard wheel hub's recess edge wheel hub rotation direction, the gyro wheel is through arranging in minor axis in the shaft hole inlays the recess of locating wheel hub both sides outer fringe. The utility model discloses need not to change the change that the wheel direction can realize advancing direction, the operation is nimble light and handy steady, simple structure, convenient assembling, the maintenance cost is lower.
Description
Technical field
The utility model belongs to cardan wheel technical field, particularly relates to the super-silent cardan wheel that a kind of structure is simple, easy to assembly.
Background technology
Being of wide application of cardan wheel, as the article that case and bag, go-cart, robot etc. need all directions freely to advance.Traditional cardan wheel just can change direct of travel when need forward the direction consistent with external force direction to, therefore generally arranges wheel carrier, vertical shaft etc., and thus, the structure of cardan wheel is general comparatively complicated, assembles also more loaded down with trivial details, short-lived.Also the cardan wheel having part can change direct of travel under external force without the need to wheel turns direction at present occurs, but double freedom mechanism need be formed by large and small waist drum, its wheel hub or support shape also more special, processing inconvenience, the change of direct of travel is also comparatively required great effort.
Utility model content
For overcoming the problems referred to above, the utility model provides a kind of super-silent cardan wheel, and structure is simple, easy to assembly.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of super-silent cardan wheel, the wheel rim comprising wheel hub and be made up of some rollers, described wheel hub is assemblied to form by outside wheel hub, middle wheel hub, inner side wheel hub, described roller is dolioform, the wheel rim place of described wheel hub two sides is evenly provided with the groove that some and dolioform roller mates, the groove of described outside hub side and the groove of inner side hub side are crisscross arranged, the groove of described outside wheel hub and inner side wheel hub is provided with axis hole along two cell walls in hub rotation direction, and described roller is embedded in the groove of wheel hub both sides outer rim by the minor axis be placed in axis hole.
Be arranged on carrier by the cardan wheel of 2 or 4 these utility models, owing to utilizing roller as wheel rim, hub rotation, to a certain roller, applies the external force identical with this roller sense of motion, carrier can be made to move in the direction, realizes 360 degree thus and comprehensively to advance.
As preferably, described roller is 5.Stagger between roller 72 degree of angles, effect of advancing is better.
Further, be connected by screw between described outside wheel hub, middle wheel hub, inner side wheel hub.Assembling and dismounting are all very simple, substantially increase production efficiency, reduce maintenance cost.
Further, described outside wheel hub, middle wheel hub, inner side wheel hub adopt engineering plastics mold pressing to form.Process easy, lighter weight.
The beneficial effects of the utility model are as follows:
1, can realize the change of direct of travel without the need to changing wheel direction, flexible operation is lightly steady;
2, structure is simple, and easy to assembly, maintenance cost is lower;
3, frictional contact surface is little, and muting function is good.
Accompanying drawing explanation
Fig. 1 is exploded view of the present utility model;
Fig. 2 is assembly drowing of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail:
As shown in Figure 1-2, a kind of super-silent cardan wheel, the wheel rim comprising wheel hub and be made up of 10 dolioform rollers 1, described wheel hub is by outside wheel hub 2, middle wheel hub 3, inner side wheel hub 4 is assemblied to form, three is connected by screw 6, the wheel rim place of described wheel hub two sides is evenly provided with 5 grooves mated with dolioform roller, the groove of described outside hub side and the groove of inner side hub side are crisscross arranged, the angle staggered is 72 degree, the groove of described outside wheel hub and inner side wheel hub is provided with axis hole along two cell walls in hub rotation direction, described roller is embedded in the groove of wheel hub both sides outer rim by the minor axis 5 be placed in axis hole.
Be arranged on carrier by the cardan wheel of 2 or 4 these utility models, owing to utilizing roller as wheel rim, hub rotation is to a certain roller, apply the external force identical with this roller sense of motion, carrier can be made to move in the direction, realize 360 degree thus and comprehensively to advance, operate steadily light and handy.
Adopt 5 rollers effect of advancing better, attrition surface is little, and muting function is good, also can increase according to actual needs or reduce number of rollers.
Outside wheel hub, middle wheel hub, inner side wheel hub adopt engineering plastics mold pressing to form, and reduce the quality of cardan wheel.
The utility model is only made up of axle, roller, wheel hub, screw, and assembling is simple, and production efficiency is high, and maintenance cost is low.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
