Description
Technical field
The utility model relates to a kind of rolling guide-rail pairs, and specifically a kind of a plurality of slide blocks can be made staggered reciprocating rolling guide-rail pairs on guide rail.
Background technique
Development along with society, the raising of everybody daily life level, people are also more and more higher to the requirement of some automatic door of public arena, the public transport crowding phenomenon (particularly commuter time) that exists in for example present public transport occasion is the focus of social concerns always, and people wish that the Men Kaide of bus or subway is the bigger the better.Though subway speed is very fast, can save the plenty of time, because the people is many, door is little, cause the contradiction dispute easily because of crowding; And, being subjected to the restriction of door because the volume of the flow of passengers is big, the subway berthing time also will prolong.The area of opening that increases subway door is the effective and feasible method that solves congested problem.And traditional subway door is the transmission component of the secondary (see figure 2) of usefulness guiding pairs (see figure 1) or guide pin bushing as subway door, guiding pairs is similar substantially to the transport characteristics of guide pin bushing pair, to do not having staggered to-and-fro motion on guide rail or lead rail axis, the length of guide rail must just can realize its normal switch greater than the total kilometres of door so only for slide block or axle supporting base.
Existing rolling guide-rail pairs comprises the secondary and roller guide pair of spherical guide, generally is made up of guide rail, slide block, rolling element, back device, retainer etc.Its working principle is to roll in the raceway of guide rail and slide block formation by rolling element, realizes the motion of rolling guide-rail pairs.Traditional rolling guide-rail pairs is because slide block can not do not have staggered to-and-fro motion on guide rail or lead rail axis, for realizing transmission, length to guide rail has strict requirement, in some occasion, traditional rolling guide-rail pairs can not satisfy the requirement of transmission, if just the back-to-back splicing use of traditional guiding pairs can be satisfied this special transmission requirement.
No matter be that all linear rolling guides such as load guiding pairs, radially heavily loaded guiding pairs, miniature guiding pairs or roller load-carrying guiding pairss such as four directions and rolling circular guide rail pair can adopt back-to-back joining method to satisfy usage requirement.But the shortcoming that the guiding pairs of this back-to-back splicing exists is: 1, low precision, and bearing capacity is little; 2, the guiding pairs height dimension of back-to-back splicing is excessive, and guiding pairs size rationality is low.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this utility model provides a kind of rolling guide-rail pairs, this guiding pairs bearing capacity is strong, installing space is little, applicability and reliability height, slide block can be done staggered to-and-fro motion on guide rail, length requirement to guide rail is low, can satisfy special transmission requirement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rolling guide-rail pairs, comprise guide rail, slide block and rolling element, rolling element is arranged in the raceway that is formed by guide rail and slide block, slide block is arranged on the guide rail by rolling element and can moves axially along guide rail, it is characterized in that: be provided with one group and can make staggered reciprocating slide block on the peripheric surface of guide rail on guide rail.
In the utility model, the slide block quantity and the direction that are arranged on the guide rail can be determined as required, generally, two slide blocks can meet the demands, at this moment, the relative both sides of guide rail are provided with two can make staggered reciprocating slide block on guide rail, two slide blocks are in a plane, and be the bilateral rolling guide-rail pairs this moment.If desired, two slide blocks also can be in two orthogonal planes.
When needs are provided with four slide blocks, on corresponding four Vertical direction of guide rail, be provided with four and can on guide rail, make staggered reciprocating slide block, the motion of four slide blocks is not disturbed mutually.
In the utility model, single slide block is secondary the same with the Placement and the conventional guide rails of guide rail, on slide block, be provided with and the suitable groove of the sectional shape of guide rail, be respectively equipped with the raceway that cooperatively interacts in the both sides of groove and the both sides of guide rail, the rolling element of bearing load is arranged in the raceway, slide block is arranged on the guide rail by rolling element and can moves axially along guide rail, the back device that is used for rolling element is turned to is fixed on the two ends of slide block, establish retainer between slide block and the back device, so that guarantee that rolling element can not fall down from slide block.The utility model adopts the mode of slide block all being installed in a plurality of sides of guide rail, can finish multi-direction big stroke motion under the short situation of rail length.
The utility model can be designed to low noise type, by increase the mode that keeps chain between rolling element, to intercept the friction between the rolling element, eliminates the rolling element collision, reduces guiding pairs operation noise; Keep the use of chain that the collision between the rolling element is disappeared, the wearing and tearing of rolling element reduce, and can also have a small amount of lubricating grease in keeping chain, so just can realize long-term Maintenance free maintenance, have prolonged working life.Compared with prior art, the utility model is except having the secondary high capacity of conventional guide rails, high rigidity, low noise, precision height, the good characteristics such as the life-span is long, wearing and tearing are little, low energy, friction factor are little, compact structure, highly versatile, also having following advantage:
1) bearing capacity is strong.The utility model guide rail all has one or several raceway up and down, slide block can be installed respectively, see Fig. 3, the twice that is common rail pair or guide pin bushing pair with the installable slide block quantity of the guiding pairs of length like this, because the bearing capacity and the slide block quantity of same rail pair are proportional, so the utlity model has bigger bearing capacity.
2) save installing space.The utility model can not have the crossing operation of interference, with common guiding pairs or guide pin bushing parafacies ratio, the attainable range of novel guiding pairs slide block of equal length is common rail pair or guide pin bushing pair 2 times, sees Fig. 4, thereby when stroke one timing, the required installing space of guiding pairs can reduce greatly.
3) applicability height.The utility model is the same with traditional guiding pairs to be designed to different sectional shapes, and the secondary sectional shape of conventional guide rails can be easy to change into the utility model sectional shape, see Fig. 5, the user can select the guiding pairs of optimal cross section shape according to the difference of the bearer properties of own equipment.Slide block on the guiding pairs also can be designed to wide type or narrow type according to mounting type, and the user can realize installing from top to bottom or mounting type from the bottom up when the assembling of guiding pairs and slide block.
