Definitions
- the invention relates to a mechanical seal according to the preamble of the main claim.
- Mechanical seals are known in a wide variety of embodiments and generally consist of a rotating slide ring and a stationary counter slide ring. A spring element presses the two parts against each other.
- a sealing ring is attached to the stationary counter slide ring, with the aid of which a liquid escape from a housing and along the stationary counter slide ring is to be prevented.
- the sliding ring rotating with a shaft is sealed off from the shaft in order to prevent liquid from escaping along the shaft.
- the design of the mechanical seal depends on the operating conditions, the premises at the installation site and the media to be sealed.
- the invention has for its object to develop an anti-rotation device for simple mechanical seals consisting of slide and counter slide ring, which can be installed in a simple manner without additional aids.
- This object is achieved in accordance with the characterizing part of the main claim;
- the fact that the anti-rotation device is fastened outside the housing makes it possible to retrofit it later, for example during repair work, on construction sites or when adapting a centrifugal pump to changed operating conditions.
- Subclaims 2 to 4 describe how this anti-rotation device is attached to the stationary counter slide ring and to the housing.
- a particularly advantageous embodiment is the option described in claim 4, according to which the anti-rotation device is designed as a cap, which can be pushed onto the housing shoulder in the simplest way. There it is attached by means of pressing, adhesive, or ' other known means. An inexpensive. Manufacturing as a sheet metal part is possible.
- connection between the cap and the stationary counter slide ring can be made by projections of the cap acting in the axial or radial direction. Furthermore, it is also possible for a collar which extends in the axial direction to bear against the counter sliding ring in a non-positive or positive manner.
- FIG. 1 Another embodiment of the invention also shows that instead of a cap, a spring element can be attached to the housing shoulder, which engages non-positively on the housing and with a spring end in a form-fitting manner on the counter slide ring.
- An embodiment of the invention is shown in the drawing as a cross section through a mechanical seal mounted on a shaft and is described in more detail below.
- a rotating slide ring (2) is attached to a shaft (1) in a rotationally fixed manner.
- Spring elements not shown here, press this slide ring against a stationary counter slide ring (3) which is held in the housing (5) with the aid of a sealing ring (4).
- the housing (5) is designed as a molded sheet metal part, but can also consist of any other material.
- the housing (5) has a housing shoulder (6) which covers the stationary counter sliding ring (3).
- An anti-rotation lock (7) pushed onto the housing shoulder (6) from outside engages here with a projection (8) extending in the radial direction to the shaft in a groove (9) of the stationary counter slide ring (3).
- This projection (8) can also run parallel to the shaft and engage in a corresponding recess in the counter slide ring (3). Furthermore, it is possible to design the anti-rotation device (7) in such a way that a collar pointing towards the inside of the housing or away from the housing positively or non-positively encloses the stationary counter sliding ring (3) on the outside or inside.
- a spring element in the form of a tension or compression spring element can also be used. This would then have an inner diameter which guarantees a firm fit on the housing shoulder (6) and a free end of the turn engages in a recess (9) in the stationary counter sliding ring (3). It should be noted that the winding direction of the spring element and the direction of rotation of the shaft ensure that the spring element is tightened.
