Abstract
The utility model relates to a linear guide rail, which comprises a basic body and roller of two guide rails. The rectangular guide channels are provided at opposite sides of main bodies of two guide rail. The rollers are arranged crosswise inside the rectangular guide channels of the main bodies of two rails, and the end face and circle surface respectively contacts with surfaces of rectangular guide channels. The utility model not only increases moving accuracy of the guide rail, but also increases load of guide rail. A certain speed and safety still can be maintained even in case of heavy load. With low noise, the utility model can works under comparatively high temperature.
Description
Technical field
The utility model relates to a kind of linear rail.
Background technique
Linear rail at present commonly used adopts the steel ball means of rolling, but the bearing load amount is little, and movement velocity is limited, and noise is more serious, and steel ball contacts steel ball easy to wear with the some face of guide rail, has a strong impact on the precision that guide rail moves reciprocatingly.Improve guide precision, prolong guide rail working life, increase the load and the movement velocity of guide rail, the drawback that overcomes existing linear rail is necessary.
The model utility content
The purpose of this utility model provides a kind of linear rail, but existing linear rail bearing load amount is little, movement velocity is limited to solve, noise is serious, the not high deficiency of kinematic accuracy.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of linear rail, comprise two guide rail matrixes and roller, the opposite side of two guide rail matrixes respectively is provided with the right angle guide groove, and described roller is arranged in a crossed manner in the right angle of two guide rail matrixes guide groove, the bottom surface of described roller and circumferential surface respectively with described right angle guide groove plane contact; Respectively be provided with the restriction nut at two guide rail matrix two ends; The described roller outside is provided with roller rolling retainer.
The beneficial effect of linear rail described in the utility model is: improved the kinematic accuracy of guide rail, also improved the load capacity of guide rail, and still can keep certain speed, safety and stability under heavily loaded situation; Can in higher temperature environment, work; Noise is little.
