Description

FORCE-TO-TORQUE CONVERSION DEVICE
Description
The invention relates to mechanical engineering, in particular to radial force-to- torque conversion devices.
It is known a planetary gear, comprising a main gear wheel, a carrier with satellites and a sun wheel, which due to its construction is capable, within a geometrical axis of rotation, to vary, add and distribute the angular speeds and/or the torque applied [1]·
The disadvantage of this planetary gear lies in the fact that the principle of operation is based only on the application of rotational or torque moments.
The technical problem solved by the invention consists in creating a compact device converting radial force, applied and maintained constantly on the handle of the hollow carrier, into a constant torque on the output shaft, as well as increasing the reliability and maintainability.
The radial force-to-torque conversion device, according to the invention, eliminates the above-mentioned disadvantage by the fact that it comprises a cylindrical body, fixed on a base and closed with a cover. On the base is mounted by means of a bearing a hollow carrier, equipped with a handle, passing through a transverse through channel, made in the body. In the carrier is fixed a primary pinion, which is engaged with two satellites, mounted on one end of some shafts, and on the opposite end thereof is mounted a satellite. The satellites are engaged with an intermediate gear wheel, which in turn is engaged with a first sun wheel, mounted on an output shaft, on which is mounted a second sun wheel, engaged with a double gear wheel, placed on the end of a satellite, the opposite end of which is mounted by means of a base bearing, the satellite being engaged with a main wheel, fixed in a drum, one end of which is mounted by means of a base bearing, and at the opposite end is fixed a main wheel, which is connected to paired satellites, mounted, in pairs, on a shaft, on the free ends of which are mounted satellites. The paired satellites are engaged with a double gear wheel, each being mounted by means of bearings on satellites, the wheels being engaged with a main wheel, fixed in the body. The shafts are fixed, in pairs, on an abutment bar. The technical result of the invention consists in the creation of a compact device converting the radial force, applied and maintained constantly on the handle of the hollow carrier, into a constant torque on the output shaft, while the direction of the rotational moment on the output shaft depends on the direction of the constantly applied and maintained moment of radial force.
The features of the invention make it possible to convert the force applied and maintained constantly on the handle into a constant torque on the output shaft, due to the use of conjugation of the modules between the gear wheels and the planetary gears, wherein in applying and constantly maintaining a radial force on the handle of the hollow carrier, the occurring moments of force interact in accordance with the lever rule.
The invention is explained by the drawings in FIG. 1 and FIG. 2, which represent:
- FIG. 1 , radial force-to-torque conversion device, general view in section;
- FIG. 2, the schematic diagram of the moments of forces of the device, top view.
The radial force-to-torque conversion device, according to the invention, comprises the base 1 , on which is fixed the cylindrical body 2, closed with the cover 3 (Fig. 1). In the body 2 is made the transverse through channel 4 and are fixed the main wheels 5 and 6, which are engaged with a double gear wheel 7 and 8, each of which is mounted by means of the bearings 9 and 10 on the satellites 11 and 12. The device further comprises the paired satellites 13, 14 and 15, 16, mounted, in pairs, on a shaft 17 and 18, the drum 19 with the main wheels 20 and 21 and the bearing 22, the hollow carrier 23 with the handle 24, the bearing 25 and the primary pinion 26, the satellites 27 and 28 (Fig. 2), mounted on a shaft 29 and 30, the intermediate gear wheels 31 and 32, the sun wheels 33 and 34, mounted on the output shaft 35, the double gear wheel 36, the satellite 37 with the bearing 38 and the abutment bars 39 and 40 of the shafts 17, 18 and 29, 30.
The radial force-to-torque conversion device operates as follows.
Upon application and constant maintenance of the force F on the handle 24, rigidly fixed on the hollow carrier 23, which can freely displace in the transverse through channel 4, made in the body 2, there takes place an initial angular displacement of the carrier 23, which with one end is mounted by means of the bearing 25 on the base 1 , the initial angular displacement of the carrier 23 is transmitted through the teeth of the primary pinion 26, fixed on the other end of the carrier 23, towards the satellites 27 and 28, mounted on one end of the shafts 29 and 30, and at the opposite end thereof is mounted a satellite 11 and 12. The satellites 27 and 28, through the intermediate gear wheels 31 and 32, transmit the angular displacement to the sun wheel 33, mounted on the output shaft 35 and then to the sun wheel 34, which is also mounted on the shaft 35. Next, from the sun wheel 34, the angular displacement is transmitted through the double gear wheel 36, placed on the end of the satellite 37, the opposite end of which is mounted by means of the bearing 38 on the base 1 , to the main wheel 21 of the drum 19, one end of which is mounted by means of the bearing 22 on the base 1 , and then to the main wheel 20, which transmits the angular displacement towards the paired satellites 13, and 15, 16, placed on the shafts 17 and 18, on the free ends of which are mounted the satellites 11 and 12. The angular displacement from the satellites 14 and 16 is transmitted to the double gear gears 7 and 8, mounted by means of the bearings 9 and 10 on the satellites 11 and 12, which move on the inner teeth of the main wheels 5 and 6, which are rigidly fixed in body 2. At the same time, the force F, applied and constantly maintained on the handle 24, transmitted to the hollow carrier 23 through the teeth of the primary pinion 26 and the satellite 27 generates a moment of force, which acts on the shaft 29 with a value of Mi1 = F-r, acting on the satellite 11 at the peripheral location of the shaft 29, also, the initial angular displacement of the hollow carrier 23 through the teeth of the primary pinion 26, of the satellite 28 and the intermediate wheel 32 generates a moment of force, which acts on the shaft 18 with a value of M2 1 = F-3-r, acting on the satellite 11 at the peripheral location of the shaft 18, in the direction opposite to the moment of force Mi1. Thus, as a result of action of the moments of force IvV and M2 1 with a multilateral direction and an unequivocal value of the action, the satellite 11 tends to rotate towards the action of the moment of force M2 1.
According to the same principle, the initial angular displacement of the carrier 23 through the teeth of the primary pinion 26 and the satellite 28 generates a moment of force, which acts on the shaft 30 with a value of Mi2 = F-r, acting on the satellite 12 at the peripheral location of the shaft 30, also, the initial angular displacement of the hollow carrier 23 through the teeth of the primary pinion 26, of the satellite 27 and the intermediate wheel 31 generates a moment of force, which acts on the shaft 17 with a value of M2 2 = F-3-r, acting on the satellite 12 at the peripheral location of the shaft 17, in the direction opposite to the moment of force M-i2. Thus, as a result of action of the moments of force Mi2 and M2 2 with a multilateral direction and an unequivocal value of the action, the satellite 12 tends to rotate towards the action of the moment of force M2 2 Thus, satellites 11 and 12 under the action of the moments of force M2 1 and M2 2 rotate on a generator of the main wheels 5 and 6 and transmit the torque moment through the double gear wheels 7 and 8 to the paired satellites 13, 14 and 15, 16, mounted on the shafts 17 and 18 to the main wheel 20 of the drum 19, which from the main wheel 21 , through the double gear wheel 36 and the satellite 37, transmits the torque moment to the sun wheel 34, which maintains the torque moment at the shaft 35.
At the same time, the F force applied to the handle 24 is not removed, that is, it is kept constant, the hollow carrier 23 does not rotate, and the satellites 27 and 28 move on the inner teeth of the primary pinion 26.
Upon removal of the F force from the handle 24, the hollow carrier 23 is actuated, and the satellites 27 and 28 cease to move on the teeth of the primary pinion 26, blocking the rotation of the intermediate wheels 31 and 32 as well as the rotation of the sun wheel 33. In this case, the moments of force M/, M2\ and M2 2, acting on the shafts 17, 18 and 29, 30, are equal to zero, therefore the rotations transmitted from the satellites 11 and 12 through the kinematic constraints on the output shaft 35 stop. In order to resume the rotation of the output shaft 35, it is necessary to apply and constantly maintain again the force F on the handle 24, while the direction of the torque on the output shaft 35 depends on the direction of the radial force F applied and maintained constantly.
