SU993073A1 - Device for determination of unbalance value in static balancing - Google Patents

Description

The invention relates to marching, structure and can be used for static balancing of rotors.

A device is known for determining the amount of imbalance in static balancing, comprising a base, a mandrel accommodated thereon for mounting a balanced part, and a measuring mechanism in the form of a sleeve with a pointer indicated by the mandrel of a scale fixed on the basis of the measured weight connected to the sleeve. and the fixation element L1.

The disadvantages of the device are low accuracy and the manufacturer of the HodTb measurement due to the displacement of the measured weight along the axis.

The closest to the proposed technical essence is a device for determining the magnitude of the disbalance during static balancing, comprising a base, a mandrel for mounting a balanced rotor placed on the base and made in the form of a cylindrical body, a measuring mechanism located on the axis of the body and made in the form of a sleeve with arrow pointer.

connected to the mandrel, the scale fixed on the base, and the measured weight, the rotational drive of the measured weight, made in the form of an axis with a gear and spring spaced on it, ONE end associated with the axis, and the other gear with kinematically associated with the measuring wheel load, as well as fixation element С 2.

The known device is characterized by insufficient accuracy of determining the magnitude of the imbalance and low productivity of measurement, which is due to the presence of kinematic

15 transmissions linking the measured weight with the mechanism of its rotation.

The purpose of the invention is to increase the accuracy and productivity of measurement.

The goal is achieved by the fact that in the device for determining the magnitude of the imbalance in static balancing, containing a base, a mandrel placed on it for setting the balanced part and a measuring mechanism in the form of a sleeve with a pointer, fixed to the basis of dimensional cargo, connected with

30 by the sleeve, and the fixation element, dimensional, the load is made in the form of a handle connected to the sleeve so that it can be rotated in the horizontal plane and interacting with the fixation element during rotation. FIG. 1. shows the proposed device; in fig. 2 is a view along arrow A in FIG. one; on league. 3 is a view along arrow B in FIG. one; in fig. 4 - the same, in working condition. The device contains a base 1, a mandrel 2 placed on it with a balancing part 3, supported / on supporting wheels 4 and supporting wheels 5, and a measuring mechanism in the form of a sleeve b with a pointer pointer 7 on a scale 8 placed on base 1, measured weight 9 and fixing element in the form of a collet 10 movably located in the sleeve 6, the Device operates as follows. The balanced part 3 placed on the mandrel 2 is mounted on the support wheels 4 so that it rests on the wheels 5. Then the part on the mandrel is rolled on the wheels 4 to a position of stable equilibrium, in which the heavy part of the part is in the bottom vertical plane. Next, on the seat of the mandrel 2 install the sleeve b and combine the arrow 7 with zero division of the scale.8. Then, the measured weight 9 is rotated in the horizontal plane, while the collet 10 is moved and fixed on the mounting diameter of the mandrel 2. The amount of imbalance is determined by the deviation of the arrow 7 relative to the scale 8. Thus, making the load in the form of a handle connected to the sleeve rotatably in a horizontal plane and interacting with the fixation element improves the accuracy and performance of imbalance determination while statically balancing parts by eliminating the displacement of the dimensional load along the axis during the imbalance determination. Apparatus of the Invention A device for determining the amount of unbalance in static balancing, comprising a base, a mandrel disposed thereon for mounting a balanced part, and a measuring mechanism in the form of a sleeve with a pointer indicated by a mandrel of a scale fixed to the base, a dimensional load connected to the sleeve, and the fixing element, about tl and often so that, in order to improve the accuracy and performance of measurement, the measured weight is made in the form of a handle connected to the sleeve with the ability to rotate horizontally ntalnogo plane and interacting when turning with the element of fixation.
