Abstract
The utility model relates to a high-speed straight guide rail which comprises a guide rial body having a groove, column guide rails, a sliding block, a gap adjusting shaft, eccentric nuts and bearings, wherein, the column guide rails are enchased at both sides of a groove arranged in the guide rail body. Each eccentric nut is provided with an eccentric hole, and the eccentric nut can be rotatablely fixed on the sliding block. One end of the gap adjusting shaft is fixed in the eccentric hole of the eccentric nut, and each bearing is provided with a concave surface matched with the column guide rails. The bearing can be rotatablely fixed on the gap adjusting shaft, and an S shape is formed by the alternatively arrangement of a plurality of the bearings. The bearings can be glidingly fixed on the guide rail body through concave surfaces matched with the column guide rails. The gaps among the bearings and the column guide ways are adjusted by the eccentric nuts by the utility model. Thus, the utility model which is a practical guide rail ntype linear sliding bearing has the advantages of easy fabrication, high yield rate and low cost.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of guide tracked linear slide bearing.
Background technique
Bearing is a kind of accessory that is widely used in fields such as machinery, instrument, and guide tracked linear slide bearing has obtained in the instrument field using widely especially.The quality of its performance will directly influence the precision and the using effect of instrument.
At present, the high-speed straight-line guide rail of leading of industrial use generally comprises guide rail and slide block, and guide rail is provided with ball, and slide block is fixed on the guide rail slidably, and slide block slides on guide rail by ball.The guide tracked linear slide bearing of this structure exists obvious defects, and the gap between slide block and the guide rail is fixing uncontrollable, and therefore, processing is difficulty comparatively, needs higher processing precision, and reject rate is higher, and cost of production is corresponding also higher.
Summary of the invention
The utility model technical issues that need to address are a kind of high-speed straight-line guide rails of design, with overcome processing that prior art exists comparatively difficulty, need higher processing precision, reject rate is higher and cost of production is higher defective.
The technical solution of the utility model:
A kind of high-speed straight-line guide rail comprises rail body, cylinder guard rail, slide block, gap adjustment shaft, eccentric nut and bearing with groove.
Said cylinder guard rail is embedded in the both sides of rail body inner groovy;
Said eccentric nut is provided with eccentric opening, and this eccentric nut is rotatably mounted on the slide block;
One end of said gap adjustment shaft is fixed in the eccentric opening of eccentric nut;
Said bearing is provided with the concave surface that matches with the cylinder guard rail, and bearing is rotatably mounted on the gap adjustment shaft, and a plurality of bearings of addressing are staggered to S shape, and matching with the cylinder guard rail by its concave surface is fixed on it on rail body slidably.
The turn eccentric nut can be adjusted the gap between bearing and the cylinder guard rail, thereby can guarantee that bearing is moving sliding in state of the best.
The utility model has the advantages that fairly obviously, bearing fixing on slide block, and is adjusted gap between bearing and the cylinder guard rail by eccentric nut, therefore easy to process, the yield rate height, cost of production is low, is a kind of comparatively practical guide tracked linear slide bearing.
