トの向かい合った側に密封的に当接している。In a length measuring system housed in a capsule, the housing or hollow body for receiving the scale or measurement value materializing means and the scanning unit for scanning the scale is provided with a longitudinal slit. Through which an engagement member projects into the interior of the housing for coupling the scanning unit or the measurement materialization means with a movable mechanical part which lies outside the hollow body. The movement of the movable machine part, for example the movement of the movable machine part relative to the stationary machine part of the machine tool relative to the stationary machine part, for example the machine base, is transferred to the scanning unit by an engagement member or of the movable scale. In some cases, it is transferred to this. In order to protect the very sensitive parts present in the housing, its longitudinal slits have to be kept well closed. However, in the region of the engaging members, the possibility of insertable engagement must be provided. From DE 3402 613 is known a measuring device housed in a capsule for measuring the position of two objects which are movable relative to one another, the housing or hollow of which is connected to one of the objects. The body has a slit extending in the direction of movement of its movable object, which is sealed by an elastic sealing lip made of synthetic resin arranged in a roof pattern, and with the other object. An insertion engagement is performed through the engagement member that is coupled. The engagement member is associated with a structural unit provided in the housing or hollow body. German patent DE 2207374 describes one of the measuring devices of the type mentioned above, in which case a housing or hollow body is provided with a sealing element made of metal. The metal foil is held on the edge of the slit by a magnet and is lifted by this magnet only upon actuation of the engagement member. In the case of the measuring device housed in a capsule, which is described in DE 34 15 164 A1, an elastic plate material configured as a spring steel strip or a bronze strip is provided as a sealing member. , Which are arranged parallel to the longitudinal slits of a housing, fixedly and intimately on one side in the housing.
The free edges of the plate sealingly abut the opposite sides of the longitudinal slit of the housing.

る。DISCLOSURE OF THE INVENTION German Patent No. 34
The synthetic resin seal lip of No. 02613 has a tendency to be swelled by being invaded by lubricating oil or a coolant during field operation, whereby the seal lip comes into contact with the engaging member in a corrugated form and a satisfactory guarantee of its sealing action is made. Disappear. Further, under such conditions, hardening and embrittlement of the seal lip can occur. Another disadvantage of the synthetic resin sealing lip is that it causes a large frictional force at the contact portion with the engaging member into which the synthetic resin sealing lip is inserted, resulting in large wear. According to the invention of DE 2207374, the drawbacks of synthetic resin sealing lips are avoided, but the technical effort is great and the presence of a magnetic field in the region of the sensitive seal causes various problems. Very inconvenient for ferromagnetic materials in processing machines. In the technical means of DE 3415164, the unavoidable leaks at the edge of the engaging member are not excluded, i.e. these leaks are synthetic resin seals when metal sealing lips are used. It is essentially larger than the lip case. Another disadvantage is that when using only one sealing lip, the engaging member of its movable mechanical part must be accurately guided such that it constantly abuts its inelastic housing. This is a very precise guide trajectory curve for the movement of the movable mechanical part, for example in the fixed connection of the engagement member to the movable mechanical member, and the It requires precise and therefore cumbersome adjustments. The object of the present invention is to make it simple and to ensure that the sealing of the longitudinal slits of its housing or hollow body has a good long-term behavior even under highly polluted and erosive practical conditions, and A translational measurement contained within the capsule for measuring the relative movement between the two machine parts, which in that case produces the least frictional force between the engagement member and each sealing element. Creating a system.

る。The present invention will now be described in more detail by way of examples with reference to the accompanying drawings. The measuring system shown diagrammatically in section in FIG. 1 is configured as a strip measuring system. This measuring system has a housing in the form of a hollow body 1 extending in the sliding direction, which is fixed by screws 3 to a first machine part 2 such as the machine base of a machine tool (not shown). An engagement member 5 is fixed to a second machine part 4 which is slidable relative to the first machine part and which is moved for the purpose of measurement, which is of the first machine part 2. The relative movement of the second machine part 4 to be measured is transferred onto the graduated scale carrier 6. The graduation carrier 6 used as a scale embodying means is constructed as a thin closed strip, is guided via a transfer roller 7 (only shown in FIG. 1) and inside the hollow body 1. It is located in. Similarly, a scanning unit (not shown) for scanning and detecting the scale of the scale carrier 6 is fixedly arranged in the hollow body 1. Two sealing metal strips 9 and 10 which form a pair of sealing metal strips and are made of a thin spring steel strip for sealing the hollow body 1 which is closed on all sides up to the longitudinal slit 8.
Is provided inside the hollow body 1 and extends in the sliding direction over the entire length of the hollow body 1. The sealing metal strips 9, 10 are in blade-shaped contact with each other by their free edges. The engaging member 5 projects from the outside to the inside of the hollow body 1 between them.
The leaks 11 and 12 (see FIG. 3) at each edge of the engagement member 5, which cannot be excluded here, are sealed by an additional sealing unit consisting of two elastic metal strip sealing pieces 13 and 14. , These strip sealing pieces cover their flared areas on both sides of the engagement member 5 and sealingly abut on the sealing metal strips 9 and 10 on the outside. Advantageously, these metal strip sealing pieces 13 and 1
4 is fixed to the engaging member 5 or the second mechanical portion 4 in a hermetically sealed manner. Shielding member 1 attached to engaging member 5
5 serves as a rough shield of the spreading area of the engagement member 5 against contaminants which can penetrate directly into the hollow body 1 through the longitudinal slits 8. This shielding member 15 can be arranged not only in the hollow body 1 but also on the outside of the hollow body 1 on the engagement member 5 or on the machine part 4. As shown enlarged in FIG. 2, these thin elastic sealing metal strips 9 and 10 are in close contact with the engagement member 9 over a range B of a few millimeters. In this embodiment, the sealing metal strips 9 and 10 each have a thickness of 50 .mu.m, which gives an edge having a thickness of 100 .mu.m. Sealing metal strips 9 and 10
This arrangement, among others, has the advantage that a very good sealing of this is achieved over the entire length of the engagement member 5. In addition, the expansion force for the insertion engagement of the engagement members is distributed over the relatively large contact surface between the engagement member 5 and the respective sealing metal strips 9 and 10, thereby causing a small expansion. Only open pressure is generated. Due to its low friction, the wear at the engagement member 5 and at the respective sealing metal strips 9 and 10 is significantly reduced. Metal strip material for each seal 9
And 10 against the engaging member 5 and the respective metal strips 13 and 14 against the sealing metal strips 9 and 10 are shown in FIG. 3 as a longitudinal section. The engagement member 5 is preferably provided with edge edges 16 and 17, which are in agreement with the natural expansion of the sealing metal strips 9 and 10 in the inner region. Metal strip seal piece 1
Similarly, 3 and 14 are formed so that they follow the outer curve of the respective sealing metal strips 9 and 10 in the outer region. In the embodiment shown in FIG. 4, inside the hollow body 1 an outer sealing metal strip pair consisting of sealing metal strips 18 and 19, and likewise two sealing metal strips 20 and 21. And a pair of inner sealing metal strips. The respective sealing metal strips 18, 19, 20 and 21 of both sealing metal strip pairs are attached at their free ends to the engaging member 5 which projects through the longitudinal slit 8 inside the hollow body 1. Abut in a sealed manner. On the engagement member 5 itself, the two metal strip sealing pieces 22 and 23 forming a sealing unit are moved only slightly by mechanical fixing means 24 or fixedly in an adhesive bond. Are arranged and abut against each sealing metal strip 20 and 21 of the inner sealing metal strip pair.
