Description
- The invention concerns a linear rolling bearing comprising a guide rail and a guide carriage that partially surrounds the guide rail and is supported by rolling elements for sliding on two long sides of the guide rail, the rolling elements being arranged on each of the two long sides in at least two parallel, endlessly re-circulating rows of rolling elements while being guided by spacers that are situated in said two rows between the rolling elements.
- Linear bearing guides are known in which the rolling elements are guided by separate, inter-connected chain links. These re-circulating chains are configured as pull chains. It is also known from a number of patent publications that such a pull chain can be configured as an open or a closed chain. Furthermore, there already exist several patent applications that describe a pull chain not only for a single row of rolling elements but also as double sprocket chains for two re-circulating rows of rolling elements. One such construction is disclosed in the publication EP 0 845 611 A1. This shows a linear rolling bearing of the initially cited type in which an open chain is used on each long side of the guide rail as a guide for two endlessly re-circulating rows of balls. Each chain comprises in its central region situated between the rolling element rows, a flexible connecting strip on whose long sides spacers are arranged spaced behind one another. Rolling elements configured as balls are arranged in the spaces between the spacers. This construction therefore results in the formation of a double row ball chain. However, this chain has drawback that the individual chain links can rupture easily.
- It is an object of the invention to provide a linear rolling bearing that is silent in running and possesses a high level of operational safety.
- This and other objects and advantages of the invention will become obvious from the following detailed description.
- According to a first proposal, the invention achieves the above objects by the fact that on each long side of the guide rail, a common spacer for both of said two rows is inserted between every two adjacent rolling elements of a first of said two rows and between every two adjacent rolling elements of a second of said two rows. According to a second proposal, the invention achieves the above objects by the fact that on each long side of the guide rail, every two adjacent rolling elements of a first of said two rows and every two adjacent rolling elements of a second of said two rows are guided in a common spacer for both of said two rows. In this way, chains can be dispensed with, so that the drawback of rupture of the chain links is eliminated.
- The features proposed by the invention make it possible to obtain a high degree of reliability. Due to the fact that the spacers of the invention act as double sprocket spacers that are guided by the rolling elements and not, as is the case with pull chains, in separate channels provided for link plates, less friction occurs and thus also less friction loss. Since the invention does not require link plates, it is also possible to reduce design space.
- In their regions situated between the two parallel rows of rolling elements, the spacers may comprise a V-shaped notch into which a retaining bar fixed on the guide carriage adjacent to each long side of the guide rail can engage. The rolling elements guided by a spacer can be enclosed over a larger portion of their circular periphery by the material of the spacer.
- A plurality of spacers can be manufactured as plastic parts in the form of a single composite structure by injection molding, a common, thin connecting web that can be easily torn off being formed on every two successive spacers. In the region of rolling element osculation, one or more spacers may comprise pockets that can be used as lubricant reservoirs. The spacers may also be made out of a porous material that stores and continuously releases lubricant.
- Examples of embodiment of the invention are represented in the drawing and will be described more closely in the following.
- FIG. 1 is an end view of a linear rolling bearing of the invention, also showing a partial cross-section;
- FIG. 2 is a side view of the linear rolling bearing, also showing a partial longitudinal section;
- FIG. 3 is a detail showing two parallel rows of rolling elements with two spacers, in a vertical section;
- FIG. 4 is a view of a spacer as seen in the direction of the arrow IV of FIG. 3;
- FIG. 5 is a detail showing two parallel rows of rolling elements with three spacers modified with respect to FIG. 3, in a vertical section;
- FIG. 6 shows the upper row of rolling elements of FIG. 5 with the spacers, in a vertical section;
- FIG. 7 shows the rolling element rows of FIG. 5 with the spacers comprising lubricant pockets.
- FIGS.1 to 4 show a guide system in end and side views. A
guide carriage 2 is slidingly supported on aguide rail 1 byrolling elements 3. Theguide carriage 2 contains a total of four re-circulatingrolling element rows rolling element rows rolling element row 4 is the upper row whereas therolling element row 5 is the lower row. The system represented in FIG. 2 has a symmetric construction. Therolling elements 3 in the present case are configured as balls. However, it is conceivable to use rolling elements of any other geometric shape, for example, barrel-shaped or cylindrical rollers. Theguide rail 1, on which theguide carriage 2 can slide in axial direction is configured as a profiled rail. Sliding is made possible by the rolling of therolling elements 3 on theguide rail 1 and on theguide carriage 2. - During axial displacement, the
rolling elements 3 circulate in theguide carriage 2. If no spacers were provided, the rolling elements could knock against one another during the displacement of theguide carriage 2 and thus produce noises. To prevent such a production of noises, therolling elements 3 are separated from one another byspacers 6. Eachspacer 6 is configured so as to simultaneously separate tworolling elements 3 of theupper row 4 and tworolling elements 3 of thelower row 5 from one another. Such a spacer is represented in FIGS. 3 and 4. - A further embodiment of a
spacer 7 is shown in FIGS. 5 to 7. In this case, tworolling elements 3 of theupper row 3 are connected to tworolling elements 3 of thelower row 5, so that a total of fourrolling elements 3 are arranged on eachspacer 7. Further, thisspacer 7 is configured so as to surround therolling elements 3 to the extent that they cannot fall out. A plurality ofspacers 7 are arranged in a row behind one another and are in contact with one another through theircontact surfaces 8 as shown in FIG. 5. - In the side view of the spacers6 (or 7) shown in FIG. 4, a V-shaped notch is to be seen that serves to retain the spacers and as an additional guide groove for a
retaining bar 10 also provided in theguide carriage 2. Thisretaining bar 2 can be seen in FIGS. 1 and 2. As an alternative to thenotch 9 shown in FIG. 4, a notch of any other shape may also be implemented. Theretaining bar 10 is connected with both its ends to the ends of theguide carriage 2. Theretaining bar 10 is arranged between therail 1 and thespacers 6 of therolling element rows - If the
guide carriage 2 is removed from theguide rail 1, theretaining bar 10 prevents the spacers 6 (or 7) and therolling elements 3 from falling out of theguide carriage 2. Therolling elements 3, configured as balls, are surrounded by thespacers retaining bar 10 can be made of plastic or wire or any other suitable material. - To simplify mounting, the
spacers 7 made by injection molding can be interconnected by a thin connectingweb 11 as illustrated in FIG. 6. However, this connection should be so thin, that the connectingwebs 11 tear open after a few circulations of the rollingelement rows spacers 7 are then separated from one another. - As shown in FIG. 7, in the region of rolling element osculation, the
spacers 7 can additionally comprisepockets 12 that act as lubricant reservoirs. It is also conceivable to make thespacers 7 of a porous material that stores lubricant and supplies it continuously to the rollingelements 3. - The advantages that can be obtained with the invention are as follows.
- The spacers are guided by the rolling elements. Conventional pull chains require a separate guide channel for guiding link plates; this increases the friction surface and thus also the friction resistance. The use of spacers therefore reduces friction.
- Besides this, conventional pull chains can tear apart as a result of dirt accumulation and under high accelerations, so that operational safety is considerably reduced. The use of spacers endows the system with a much higher operational safety and reliability.
- Finally, design space requirement is also reduced because link plates are dispensed with.
