Abstract
The invention relates to a linear guide rail applicable to high-load occasions, and the linear guide rail comprises a rail and a sliding block. Four lines of ball chains are arranged in the sliding block; four rolling running surfaces matched with the ball chains are formed on the rail; returners are installed at two ends of the sliding block; the sliding block and the returners form a circulating loop for the ball chains to perform circulating motion; a roller running groove is formed on the upper surface of the rail, a line of roller chain is arranged in the sliding block; and the sliding block and the returners form a roller circulating loop for the roller chain to perform circulating motion. The linear guide rail has the advantage that the line of the roller chain is added on the basis of the prior art and is used for bearing high load, reducing the stress and abrasion of the ball chains, prolonging the service life of the linear guide rail, and improving the accuracy of the linear guide rail during high load running.
Description
Technical field
The present invention relates to the linear guidance device technical field, especially a kind of linear rail that is applicable to the high capacity occasion.
Background technique
Linear rail claims again line rail, slide rail, linear guides or linear slide rail, is used for the straight reciprocating motion occasion, has the rated load higher than linear bearing, can bear certain moment of torsion simultaneously, can be in the situation that high capacity realizes high-precision straight line motion.The effect of linear rail is to support and the guided-moving parts, does linear reciprocating motion by given direction.Decide according to pressing friction character, linear rail can be divided into the kinds such as sliding friction guide rail, rolling friction guide rail, elastic-friction guide rail, fluid friction guide rail.Now commonly used is the rolling friction guide rail, comprises track and slide block, is provided with rolling element in slide block, has the rolling tread of rolling element on track, and slide block by rolling element and track sliding movingly.
Existing linear rail generally has four row rolling elements, and wherein two row are positioned at the shoulder position of track, and other two row are positioned at the waist location of track.This type of linear rail is applicable to the not high occasion of load, and when needs bore high load, wearing and tearing aggravation after the rolling element of this type of linear rail is received present and increased caused precision to reduce, and shorten working life.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the not high technical problem of load that prior art cathetus guide rail can bear, a kind of linear rail that is applicable to the high capacity occasion is provided, can improve the load capacity of linear rail, improve precision when high capacity, increase the service life.
the technical solution adopted for the present invention to solve the technical problems is: a kind of linear rail that is applicable to the high capacity occasion, comprise track and slide block, be provided with four row ball chain in described slide block, have four rolling treads that match with ball chain on track, the two ends of described slide block are equipped with recoverable capsule, slide block and recoverable capsule form the circulation loop for the ball chain shuttling movement, offer the roller groove that travels on the upper surface of described track, be provided with the roller chain that row can move in described slide block in roller travels groove, form the roller circulation loop for the roller chain shuttling movement on described slide block and recoverable capsule.
As preferably, the slenderness ratio of the roller that described roller chain adopts is 3～6.
As preferably, described roller chain and roller travel and are transition fit between groove and slide block.When slide block bore larger load, slide block pushed roller chain to orbital direction, and roller chain is just got involved and born pressure, and roller chain is in free state when bearing load is not high.
The invention has the beneficial effects as follows, the linear rail that is applicable to the high capacity occasion of the present invention, novel, be easy to make, set up a row roller chain on prior art, in order to bear high loading, reduce the stressed of ball chain, the wearing and tearing of less ball chain, the working life of prolongation linear rail, the precision when improving the long-term high capacity operation of linear rail.

Fig. 2 is the sectional view that is applicable to the linear rail most preferred embodiment of high capacity occasion of the present invention;
Fig. 3 is the stereogram of track described in the present invention.
In figure: 1. track, 11. rollers travel groove, 2. slide block, 3. ball chain, 4. recoverable capsule, 5. roller chain.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
as shown in Figures 1 to 3, the linear rail most preferred embodiment that is applicable to the high capacity occasion of the present invention, linear rail comprises track 1 and slide block 2, be provided with four row ball chain 3 in slide block 2, have four rolling treads that match with ball chain 3 on track 1, the two ends of slide block 2 are equipped with recoverable capsule 4, slide block 2 forms with recoverable capsule 4 circulation loop that supplies ball chain 3 shuttling movements, offer the roller groove 11 that travels on the upper surface of track 1, being provided with row in slide block 2 can be at the travel roller chain 5 of groove 11 interior motions of roller, form the roller circulation loop for roller chain 5 shuttling movements on slide block 1 and recoverable capsule 4.
As preferably, the slenderness ratio of the roller that roller chain 5 adopts is 3～6.
Roller chain 5 and roller travel and are transition fit between groove 11 and slide block 2, are interference fit between ball chain 3 and rolling tread and slide block 2.When slide block 2 bore larger load, slide block 2 was to track 1 direction extruding roller chain 5, and roller chain 5 is just got involved and born pressure, and roller chain 5 is in free state when bearing load is not high.
The present invention sets up a row roller chain 5 on prior art, to play the effect of bearing pressure when the enduring high capacity, reduce stressed on ball chain 3, reduce the wearing and tearing of ball chain 3, thereby extend the working life of linear rail, the precision when improving the long-term high capacity operation of linear rail.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
