Description
Technical field
The present invention relates to a kind of field of mechanical technique, more particularly to a kind of the linear guide.
Background technology
The linear guide is also known as line rail, sliding rail, linear guides, linear slide rail, is used for straight reciprocating motion occasion, and can hold
Certain torque is carried on a shoulder pole, can realize high-precision linear motion in high-load situations, this.The linear guide movement effect be for
Support and guided-moving component, linear reciprocating motion is done by given direction.The linear guide mainly compares used in required precision
In high mechanical structure, between the moving element and retaining element of the linear guide do not have to intermediate medium, and use rolling rolling element.
Currently, traditional the linear guide has the following defects.
1, at work, sliding block recycles sliding by rolling element to the linear guide on guide rail, and rolling element is in contact shape two-by-two
At circulating rolling, the direction of motion between the position that rolling element is in contact two-by-two is opposite so that rolling element exists and mutually rubs two-by-two
It wipes, friction easy tos produce heat to influence the speed of service of rolling element, and prolonged friction causes the abrasion of rolling element, shortens
The service life of rolling element, maintenance times frequently increase, and cost increases.
2, the linear guide has the installation of different direction according to different workplaces, since the installation of different direction is put
It sets, the lubricating oil in lubricant reservoir cannot meet the fuel feeding and lubrication in each orientation, influence the normal operation of the linear guide,
When lubricating oil uses that only lubricating oil is arranged at bottom, lubricating oil can not just arrive top, to reach between guide rail and sliding block
It recycles in raceway, influences operation and the lubrication of the linear guide.
3, there is gap between sliding block and guide rail in the linear guide, when sliding block is covering guide rail, be easy external at work
Molecule enter guide rail both sides slot, when sliding block cover again guide rail operation when so that molecule is entered Zhu Gou, Yi Zao
At between sliding block and guide rail rolling element it is stuck.
Invention content
In order to overcome the shortcomings of that existing research, patent of the present invention provide a kind of the linear guide, compact-sized stabilization, design
