Description

Cardan wheel

Technical field:

The utility model relates to a kind of cardan wheel.

Background technology:

At present, the prior art cardan wheel generally comprises support, wheel, is used to connect the top board of load and is arranged on going up on the support to be changeed bowl and changes bowl down, wherein, be equipped with some steel balls between last commentaries on classics bowl and the support and between following commentaries on classics bowl and the support, top board, go up to change bowl, change between bowl and the support and normally use the rivet riveting together down, and wheel and support bottom also are the employing rivet usually.The cardan wheel of this structure is all rivetted by rivet owing to each parts, therefore it has the following disadvantages: 1, position on the cardan wheel between each parts and distance are fixing dead, it can not be along with suitable adjustment is carried out in the variation of load size, thereby make cardan wheel can't reach best even stress-bearing capability, damage parts easily, reduce the safety performance of its use, in other words, be closely to act on mutually under the effect of rivet between each parts of cardan wheel, neither one unloads the space of power between each parts, under the effect that is subjected to gravity, there is serious friction force between parts and the parts, time one length will be damaged parts; 2, cardan wheel can bear very big pressure in long-term use, this make the commentaries on classics bowl go up quick-fried pearl phenomenon to occur easily is the steel ball fragmentation, thereby influence the service life of cardan wheel, and adopt the connection mode of rivet make the prior art cardan wheel the replacing steel ball and current maintenance becomes very loaded down with trivial details and effort.

The utility model content:

The technical problems to be solved in the utility model is, provides a kind of not only easy to maintenance, laborsaving, and can be according to position, the distance between the load size regulated at will parts, the cardan wheel of safety performance height and long service life.

Technical solution of the present utility model is, a kind of a kind of cardan wheel with following structure is provided, and it comprises support, wheel and is arranged on going up on the support changes bowl and change bowl down; Described going up between commentaries on classics bowl and the support and between following commentaries on classics bowl and the support is equipped with some steel balls; Described go up to change bowl, support and change down between the bowl by the detouchable compound type double-screw bolt that can adjust close-fitting degree between them and be used to connect load connect; Described wheel is connected by the detouchable combined bolt that can adjust the close-fitting degree between them with the support bottom.

After adopting above structure, compared with prior art, the advantage that the utlity model has is: because compound type double-screw bolt and combined bolt are not only detachable in the utility model, change bowl, support and change close-fitting degree between the bowl down and the close-fitting degree between wheel and the support bottom but also can adjust respectively, therefore the utility model is not only easy to maintenance, laborsaving, and can be according to position, the distance between the load size regulated at will parts, thereby its safety performance is improved, and long service life prolongs.
