Abstract
The utility model relates to a linear guideway pair with reversers, which comprises the reversers at two ends of a slide block of the linear guideway pair, wherein steering rollaway nests in the two reversers are Gothic double arc rollaway nests. The steering rollaway nests are Gothic double arc rollaway nests, so that the contact area of balls and the steering rollaway nests is reduced, and noise generated when the balls turn around is reduced.
Description
Technical field
The utility model relates to a kind of linear guide pairs with reverser.
Background technique
Along with the development of Modern Manufacturing Technology, so that traditional development along with Modern Manufacturing Technology, so that huge variation has occured traditional manufacturing industry, Numeric Control Technology, electromechanical integration and industrial robot have obtained using more widely aborning.Location accuracy, guiding accuracy and the feed speed of mechanical transmission mechanism are improving constantly simultaneously, make traditional guide mechanism that great change occur.Since beginning commercialization in 1973, linear rolling guide has replaced traditional sliding straight guide rail gradually with its exclusive characteristic, is widely used in industrial production.Adapted to machinery now for highi degree of accuracy, high-speed, energy saving and the requirement of shortening product development cycle, be widely used in the machinery that various heavy combination working machine tools, numerical control machine tool, highi degree of accuracy electrodischarge cutting machine, grinding machine, industrial robot and even general industry use.At present, the manufacturer that produces linear rolling guide abroad mainly concentrates on the U.S., Britain, Germany and Japan and other countries.Domestic manufacture view at linear rolling guide also is in the starting stage.In the prior art, because the orbit radius of reverser is slightly larger than ball radius, so slide block is in moving process, raceway in ball and the reverser is that single-point contacts, area of contact is little, impact force during turning concentrates on the raceway bottom, and noise is large, and how overcoming the problems referred to above is technical barriers of related domain.
The model utility content
The technical problems to be solved in the utility model provides a kind of linear guide pairs that is provided with the reverser of low noise.
In order to solve the problems of the technologies described above, the utility model provides a kind of linear guide pairs with reverser, comprises the reverser at the slide block two ends that are provided with described linear guide pairs; The raceway that turns in described two reversers is Gothic duplex circular ares profile race.
Further, the retainer global design makes the easy to assembly of described linear guide pairs, in the situation that screw is not installed, described butt hook has pinned the reverser at two ends, can put into track to slide block assembly and carry out damping test.Described linear guide pairs also comprises guide rail, described slide block is provided with the groove that matches with the sectional shape of described guide rail, both sides are respectively equipped with at least one deck track corresponding with described guide rail in the groove of described slide block, and at least two be connected between described two reversers and the retainer corresponding with the cambered surface of described track both sides, and the cambered surface of the cambered surface of described retainer and the described track of homonymy is configured for keeping the raceway of described ball.
Further, in order better to pin the reverser at two ends, the two ends of described retainer are provided with the butt hook that links to each other with two reversers respectively.
Technique scheme of the present utility model has the following advantages compared to existing technology: (1) described raceway that turns to is Gothic duplex circular ares profile race, reduces ball and the described area of contact that turns between the raceway, the noise of generation when reducing ball and turning to; (2) retainer global design makes the easy to assembly of described linear guide pairs, in the situation that screw is not installed, described butt hook has pinned the reverser at two ends, can put into track to slide block assembly and carry out damping test.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is linear guide pairs structural drawing of the present utility model;
Fig. 2 is Gothic duplex circular ares profile race sectional drawing of the present utility model;
Fig. 3 is retainer structural drawing of the present utility model.
Embodiment
See Fig. 1, a kind of linear guide pairs with reverser comprises the reverser 3 at slide block 6 two ends that are provided with described linear guide pairs; The raceway that turns in described two reversers 3 is Gothic duplex circular ares profile race.
Gothic duplex circular ares profile race: being shaped as of the rolling surface of steel ball " some contact " structure, employing with the steel ball circular arc ditch of approximate curvature directly, form " Gothic shape " ditches (Gothic) with two circular arc ditches.Its reason is, during the point contact, load rating is little, and single circular arc ditch is when axle direction bears loading, and point of contact is easily mobile, and feed accuracy is bad, and axial stiffness also reduces.
Described linear guide pairs also comprises guide rail 1, described slide block 6 is provided with the groove that matches with the sectional shape of described guide rail 1, both sides are respectively equipped with at least one deck track corresponding with described guide rail 1 in the groove of described slide block 6, and at least two be connected between described two reversers 3 and the retainer 5 corresponding with the cambered surface of described track both sides, and the cambered surface of the cambered surface of described retainer 5 and the described track of homonymy is configured for keeping the raceway of described ball 4.
The two ends of described retainer 5 are provided with the butt hook 5-1 that links to each other with described two reversers 3 respectively.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
Claims (3)
1. linear guide pairs with reverser comprises the reverser at the slide block two ends that are provided with described linear guide pairs; It is characterized in that, the raceway that turns in described two reversers is Gothic duplex circular ares profile race.
2. the linear guide pairs with reverser according to claim 1, its this be characterised in that, described linear guide pairs also comprises guide rail, described slide block is provided with the groove that matches with the sectional shape of described guide rail, both sides are respectively equipped with at least one deck track corresponding with described guide rail in the groove of described slide block, and at least two be connected between described two reversers and the retainer corresponding with the cambered surface of described track both sides, and the cambered surface of the cambered surface of described retainer and the described track of homonymy is configured for keeping the raceway of described ball.
3. the linear guide pairs with reverser according to claim 2, its this be characterised in that: the two ends of described retainer are provided with respectively and described two butt hooks that reverser links to each other.
