Yaa fig. 13, 14. 15, 16, 17 shows the rotor of the RT.

The rotor PT consists of a shaft 25. At one end of which a flat circular plate 26 is rigidly, coaxially and perpendicularly fixed to it, through circular holes 27 and a blind key groove 28 are made to the second perpendicular to its plane. The opposite end of the shaft 25 ends with a tetrahedron 29, an annular groove 30 is made between the plate 26 and the tetrahedron 29, and a threaded portion 31 is formed on the shaft between the annular groove 30 and the plate 26.

The rotor PT also includes a drum 32 and a grill 33 with a central through circular hole for the shaft 25 and circular holes similar to the holes of the shaft 27.

The drum 32 is made in the form of a cylinder with flat ends (Fig. 13. 14). A through hole is made in the drum body, in

which passes the corresponding section of the shaft 25 (Fig, 14).

The through body is made through

. circular holes 34 located 5 just like the holes 27 in the plate 26 of the shaft 25, while the axis of the holes 34 are parallel to the longitudinal axis of the drum 32. Each hole 34 of the drum communicates with a through longitudinal groove 35 located along the radius of the drum and made from a circular hole 34 to the outer surface of the drum.

Pushers are installed in all holes 34 of the drum.

5 rods 36 of circular cross section with a supporting collar 3 in its middle part and a threaded section 38 from the supporting collar 37 to one end of the shtos.

On the threaded section 38 of each rod

0 threaded pin 39 and thrust nut 40 {Fig. 16), and the dimensions along the length of the nut 40 and the pin 39 are chosen so that with the nut screwed to the stop and locked, for example, with

5 from self-unscrewing, on the threaded portion 38 of the stem there remains a portion of free thread between the cotter 4 of the shaft 40 and the end of the support collar 37, within which the pin 39 can move along the thread.

0 At the end of each rod, a groove 41 is made for a screwdriver.

The rotor of the PT is assembled as follows,

In the central hole of the drum 32

5, the shaft 25 is passed until the end of the drum abuts against the end of the plate 26. The drum is oriented in such a position that the centers of all the holes 34 in the drum are aligned with the centers of the corresponding holes 27

0 and shaft plate 26. The dowels 42, which are arranged in such a way that when the holes 27 and 34 are aligned, enter the longitudinal grooves 35 of the drum, are prevented from mutual circular displacement of the shaft and the drum.

5 Next, pushers are installed in the holes 34 of the drum 32 so that the ends of the thrust nuts 40 are in contact with the plate 26 of the shaft 25, and the pins 39 of the pushers are placed in the longitudinal grooves 35 of the bar 0, while the rods 36 of the pushers and pins 39 protrude beyond the dimensions of the drum, and the dimensions of are selected so that they can also be freely displaced in the longitudinal direction relative to the bar 5. On the rods 36 of all pushers install springs 43 in contact with the ends of the support collar 37.

Next, a grate 33 is installed on the shaft 25 throughout the entire central hole, the holes of which enter with a protrusion

the ends of the rods 36 of the pushers, and the lattice itself is fixed against rotation by means of its keys 44, which are located in the longitudinal grooves 35 of the drum.

Thereafter, a nut 45 is screwed onto the threaded portion 31 of the shaft, which lifts the ends of the drum 32 to the ends of the plate 26 and the grill 33.

On the outside of the grill 33, the serial numbers of the rods are plotted near each rod, in this case the number of rods is exactly sixteen.

The lock also includes a clutch (Fig. 18-23).

The coupling includes a housing 46 in the form of a stepped cylinder with an internal through-stepped cylindrical hole. On the outside, a flange 47 in the form of an annular plate, in which a through hole 48 of a conical shape is formed, is rigidly fastened with it.

In the coupling housing, on the base side of the larger diameters, on the side of the inner cylindrical hole of larger diameter, a through stepwise cylindrical hole is made, the axis of which is perpendicular to the axis of the coupling body 46, in which the button 49 is installed, connected by a thread to the latch 50, while the button 49 is spring-loaded relative to clutch housing with spring 51.

Also, in the body of the larger base of the coupling body, two through threaded holes are made perpendicular to the axis of the housing, in which threaded pins 52 and 53 are screwed. A tooth 54 is rigidly fixed to it from the outside of the smaller base of the coupling housing.

A cylindrical sleeve 55 is mounted in the inner cavity of a larger diameter of the coupling housing with the possibility of axial displacement, spring-loaded relative to the step of the cavity of the coupling housing by a spring 56.

In the sleeve 55, a through cylindrical bore 57 is made, ending with a tetrahedral bore 58. The diameter of the bore 57 is selected so as to mate with the corresponding portion of the shaft 25 of the rotor PT along the landing, and the size of the four-bore bore 58 allows it to fit four without turning - grannik 29 of the rotor shaft of the RT.

On the lateral surface of the sleeve 55 perpendicular to its axis, a through groove 59 is made, into which a threaded pin enters

53 screwed into the sleeve housing to prevent the sleeve from falling out.

On the side surface of the sleeve 55 are also made two grooves 60 for the retainer

50 buttons.

The lock also includes a stator ST (Figs. 2, 6, 27), made in the form of a hollow cylindrical sleeve with a flange 61 and with ribs 62 made on the inner side surface of the stator (Fig. 34). At the end of the stator, opposite the end with the flange 61, tabs 63 (Fig. 8) are made with holes for screws 3 used for fastening to the door.

5 Assembling a pre-pinned lock is carried out as follows.

The rotor PT is mounted coaxially with the stator CT in the inner cavity of the stator so that the rotor plate 26 25 abuts against the stator flange 61 (Fig. 6.27) and the grating 33 is in contact with the inner side surface of the stator, while the pusher pins 3 are placed between

5 ribs 62 stator with overlap.

The stator ST together with the rotor RT are installed in the cylindrical hole of the door (Fig. 6), while ETORL the stator is located with its flange on the outside of the door,

0 and tabs 63 on the inside of the door (Fig. 8).

Next, a housing is mounted on the rotor shaft 25 through the hole 10, orienting it so that its plate 11 is

5 is oriented to the inner surface of the door 1, and the cylindrical part 7 of the housing was located below (Fig. 3, 6). After installing the trim 2 from the outside of the door, the screws 3 are passed through the holes 13 of the box part 9 of the housing through the holes 24 in the valve box and the gate of the gate, the holes in the doors are passed and screwed into the blind threaded holes in the trim.

Two other screws 3 are passed through holes 15 made in tides 14 of the other part 7 of the housing, then through the holes in the legs of the stator 63 (Fig. 8), through the holes in the door and screwed into the blind holes in the cover 2.

Then, a spring 64 and a ball 65 are installed in the hole 16 (Fig. 11), and a coupling is mounted on the rotor shaft 25 along its central hole so that the flange 47 of the housing 46 of the coupling faces the lock body and into the hole 48 (Fig. 18) Sha'ik 65 sinks.

The clutch is fixed on the shaft 25 and with the help of a threaded pin 52, the end of which enters after it is wrapped in the annular groove 30 of the shaft

The shaft 25 and the coupling can be in two positions.

Fig. 6 shows a state in which the shaft 25 and the coupling are disconnected while the shaft square 29 is outside the coupling and the sleeve 55 is kept from axial displacement by the latch 50 of the button 49 (Fig. 20), which is located in the groove 60 of the sleeve 55 of the coupling.

When the button 49 is pressed, the latch 50 leaves the groove 60, the sleeve, under the action of the spring 56 (Fig. 5, 6), moves to the position shown in Fig. 7, and the latch 50 enters the second groove 60 of the sleeve, the shaft square 29 enters a tetrahedral hole 58 bushings 46,

In this position, the shaft 25 and the coupling are engaged.

Preliminary encryption of the lock is carried out as follows.

Before installing the rotor in the stator (Fig. 13-17) with a screwdriver, the blade of which is installed in the groove 41 on the end of the rod 36 of the pusher, the rod is rotated, Some of the pins 39 are set to the stop in the ends of the thrust nuts 40 (Fig. 27, 29). In this position, the pins 39 are engaged with the stator ribs 62 and therefore do not interfere with the rotation of the rotor.

The other part of the pins 39 is in a position where their ends abut against the ends of the support collars 37 of the rods (Figs. 31, 33), and in this position, the pins are engaged with the stator ribs 62 and therefore prevent rotation of the rotor.

A key is used to open the lock (Figs. 245, 25 and 26).

The key is made in the form of an annular rim 66, connected by means of radial jumpers 67 with an annular plate 68, located in the cavity of the bead 66 and aligned therewith. In the plate 68, threaded holes 69 are made whose axes are perpendicular to the plane, and the number corresponds to the number of pushers in the rotor. Radial spaced threaded holes are made in key rim 66.

In the neutral position, all the pins 70 of the key are screwed into the radial holes of the rim, the number of pins 70 corresponds to the Number of pushers of the lock (Fig. 24).

In FIG. 25 shows the key in the operating position.

For example, three pins 70 are turned out of the threaded holes of the rim 66 and screwed into the holes 69 of the plate 68.

In this case, for definiteness, it is shown that the pins 70 are screwed into the holes with numbers 1, 2, and 3 for convenience, all

holes 69 are numbered - i to 16), while the numbers and location of holes 69 correspond to the numbers and location

. stocks (Fig. 15).

 this case pusher pins with

Numbers 1, 2, and 3 are predefined in position as shown in FIG. 31 and 33,

The pushers pins with numbers from 4 to 16 are installed in the position, as shown in Figs. 27 and 29,

The lock opens as follows

The pins 70 of the key are inserted into the hole 27 of the plate 26 of the shaft 25, the key being oriented in the necessary direction so that the key of the key 71 fits into the corresponding groove 28 in the shaft plate. When the key is pressed, the pins 70 depress the respective rotor pushers and disengage (Fig.

0 32 and 34) pins 39m of the rib 62 of the stator. Then the key is rotated around its own axis, rotation through the key key 71 and the groove 28 of the plate 26 is transmitted to the shaft 25, which in this case should be engaged with

5 coupling (Fig. 7).

Further, rotation from the shaft through the shaft square 29 is transmitted to the sleeve 55 of the sleeve and through the threaded pin 53 is transmitted to the sleeve body 46. In this case, the tooth 54

0 clutch s depresses the lock 17 of the locking mechanism, the tooth 18 of which disengages from the teeth of the valve 22, and the tooth 54 of the coupling interacts with the teeth of the valve 22 and informs it of the progressive movement of 5 x (movement.

When the clutch is rejected (Fig. 6), the rotation of the rotor does not transmit the movement of the bolt of the locking mechanism,

When pushing pushers arranged as shown in FIG. 27 and 29, their pins 39 are engaged with the stator ribs 62 and thereby prevent rotation of the rotor.

The number of combinations N e lock is determined from the following expression:

N ITCM1.

1 ml

where M is the total number of pushers; Q mi is the minimum number of pushers whose pins mesh with the stator ribs;

gp2 is the maximum number of pins whose pushers are engaged g with stator ribs.

For example, with M 16; mi 5; ma 11, N 61542.
