Description

The invention relates to automatic noKaabiBaromiiKi recorders using a compensation measurement method, and can be used to record and display measured speeds. The known two-channel recording devices, comprising a housing with a rotary lid and a scale, within which there are two tracking systems with an executive engine along a single channel connected by a flexible transmission with a carriage carrying a writing device and a pointer of reference, and a lenticular mechanism, they do not allow the high quality of registration and indication of the parameters of technological processes and do not allow the operator to observe by the approach of the process being serviced,; are located far from the instruments that cannot be directly at production facilities due to the lack of operational space and the necessary protection from the harmful effects of high temperatures, chemical reagents, electromagnetic fields, shocks, vibrations, moisture, etc., 2. - racirecquek: areas of application of two-channel regulators and an increase in the registration and indication of veterinary measurements ,. This goal is achieved so that a duplicating circular switch is installed on the rotary lid of the device with a pointing central arrow along each channel connected by a flexible gear with a drum fixed on the shaft carrying a helical spring fixed on the rotary cover and connected through a flexible coupling with a profiled shaft, mechanically connected with a hollow shaft, movably mounted on the instrument case, with a profiled end made on one end of the hollow shaft, and Its adjustable diameter drum is connected by a flexible gear with the motor shaft. Fig, 1 shows a structural diagram of the proposed device; ka fig 2, a general view.

The device comprises a housing with a rotatable lid (not shown on the Drawing), inside which there is a tape mechanism and two tracking systems with an executive motor ID (ID) along

each channel on whose shaft the drum 1 (1) is attached, connected by a flexible gear 2 (2) to the carriage 3 (h) carrying a writing device with a reference indicator and having the ability to move along the scale 4 (4), and the drum 5 (5 ) associated with a flexible gear 6 (b) with a split drum 7 (7) having an adjustable diameter and fixed to the end of the empty shaft 8 (8) located in the supporting

bearings of the housing 9 (9) and having a conical socket and fixed on the chassis of the device, at the other end of the shaft 8 (8) there is a profiled end B (A), for example, i in the form of an open worm nut. On

The device cover is mounted in bearings with the shaft of the driven half coupling 10 (10) with the coil spring 11 (11) fastened on it by the drum 12 (12) and the flexible coupling 13 (1e) connected to the shaft 14 (14) mechanically connected, for example, by means of a key 15 (15 /) with a shaft 8 (8) and a closed protective casing 16 (16). The bend front 17 (17) connects the drum 12 (12) to the sleeve 18 (18), on which the clamp & indicating arrow j 19 (19v, indicating the measurement results on the duplicating circular scale 2O, at the maximum mark of which a stop 21 is installed in the instrument cover

The device works as follows

The measured value is recorded on a carrier by a writing device located on the array 3 (G), moved along the main scale 4 (4) by the executive motor ID (ID), which through flexible transmission 6 (6) the split drum 7 (7) and the hollow shaft 8 (8) simultaneously transmits rotation to shaft 14 (14), which rotates the central arrow 119 (197 relative to the duplicating far-seeing dial scale 20. When opening the instrument cover, the key 15 (15) of the shaft 14 (14 leaves the keyway of the hollow shaft 8 (8 ). At the same time, the shaft 14 (14) under the action of the spiral springs 11 (11) and is deployed through the drum 12 (12), a flexible transmission 17 (17 and bushing 18 (18f) rotates the arrow 19 (19), pressing it against the stop 21 as shown in phantom

in fig. 1. With such a position of the arrow on the process of assembling the device, it should be combined 1 1 the position of the key 15 (1 in) and the sockets of its hollow keyway of the hollow shaft 8 (8). In this case, the reference indicator on the carriage 3 (3) should also be located at the maximum reading of the main Scale 4 (4). Such matching of the elements of the kinematic chain of the device allows closing the lid at any position of the pointer on the main scales. When closing the lid of the device, the conical end of the shaft 14 (14) first slides along the conical surface of the bell of the housing 9 (9), then along the profiled surface of the shaft end 8 (8), at the same time, spiggly | yo before the key 15 (15) is aligned with the keyway of the shaft 8 (8). In this case, the rotation of the shaft 14 (14) leads to the rotation of the arrow 19 (19) and its adjustment to the reference division of the scale 2O, which corresponds to the reference division of the main scale 4 (4).

The proposed two-channel recorder; the pointing device allows for the long-term reading of readings on a duplicate dial, increased in length by several times in comparison with the main scale of the instrument, by means of the central arrow; associated with the actuator of the tracking system for each channel, using a device containing a kinematic junction of a flexible drive, moving the central arrow synchronously with respect to the reference indicator on the main scale of the instrument, while ensuring high accuracy of recording and display of measured parameters
