Definitions
- the invention relates to a rheometer for determining the deformation and / or
- Flow behavior of a test substance with a measuring vessel which is open to one side and which forms a cavity in its interior for receiving the test substance, a measuring body arranged in this cavity and a shaft connected to the measuring body via the open side.
- Such a rheometer is known from document DE 199 11 441 Al.
- This document describes a rheometer with a measuring cup, a measuring cylinder arranged in the measuring cup and an input or output shaft which is connected on the one hand to the measuring cylinder via the open side of the cup and on the other hand to a drive and / or torque measuring unit.
- the object is achieved according to the invention by the features of independent claim 1.
- Preferred embodiments of the invention are specified in the subclaims, each of which can represent an aspect of the invention individually or in combination.
- the measuring vessel has a sleeve element which extends from the side of the measuring vessel opposite the open side into the interior of the
- Measuring vessel extends, the shaft completely engages through the sleeve element. In this way, the shaft is passed through the measuring vessel, which makes the structure compact. As mentioned, the shaft completely passes through the sleeve element so that it is connected to the measuring body via the open side.
- the test substance is to be understood as the sample whose deformation and / or flow behavior is to be investigated.
- the rheometer has a drive and / or torque measuring unit connected to the shaft, which is arranged on the side of the measuring vessel opposite the open side.
- This unit can be arranged directly on the measuring vessel on this opposite side, which makes the construction quite compact.
- the cavity (for receiving the test substance) completely or at least partially surrounds the sleeve element.
- the measuring vessel has a shape similar to a wreath-baking shape.
- the measuring body is detachably connected to the measuring body.
- the detachable connection can
- the measuring vessel is designed to be rotationally symmetrical.
- Fig. 1 a rheometer according to a preferred embodiment of the invention in a sectional view.
- the measuring vessel 12 is a measuring vessel 12 open to one side 20, which in turn has a cylindrical outer shape and has a sleeve element 22 arranged inside the measuring vessel 12.
- This sleeve element 22 extends from a bottom 24 of the measuring vessel 12 on the side 26 opposite one side 20 to almost the opening of the measuring vessel 12.
- a cavity 28 for receiving a test substance 30 to be examined (which can also be called Can designate sample).
- the sleeve element 22 forms a bushing for the shaft 16, which on the one hand is connected to the drive or
- Torque measuring unit 18 and on the other hand is connected to the measuring body 14.
- the shaft 16 extends from one side to the other 20, 26 of the measuring vessel, completely penetrating the sleeve element 22.
- the drive or torque measuring unit 18 is either a motor or a
- the shaft 16 serves as a reference to the measuring body 14
- Drive shaft for transmitting a torque from the drive unit 18 (motor) to the measuring body 14 or as an output shaft for transmitting a torque from the
- the drive or torque measuring unit 18 is arranged on the side 26 of the measuring vessel 12 opposite the opening of the measuring vessel 12, ie below the measuring vessel 12.
- the shaft 16 extends through the measuring vessel 12 to the side 20 of the vessel 12 on which the opening is located, that is to say the top of the measuring vessel. There, the shaft 16 is detachably connected to the measuring body 14.
- the measuring body 14 is designed, for example, as a measuring paddle or as a measuring cylinder.
