Description

The utility model relates to hand tools for screwing and unscrewing threaded fasteners.

Multipliers or manual torque amplifiers are universal devices whose purpose is to disassemble and assemble threaded joints. The principal feature of such devices is that they allow you to develop large values of the working (output) torque with initially small values of the applied (input) force. A multiple increase in the moment of force occurs due to the planetary gear reducer located inside such a key. It has a high gear ratio and increases the angular velocity of the output shaft. The developed force depends on the design of the mechanism and the set of gears in the planetary gearbox.

Depending on the type of drive, torque multipliers can be:

- mechanical hand. Used at low workloads with threaded joints;

- with pneumatic drive. Used for fasteners in conditions where the use of a hand tool is impractical, and the use of an electric drive is impossible;

- with electric drive. Such a key-multiplier is used for high-performance work on tightening and loosening a large number of fasteners.

The prior art manual multiplier (US 5616095, class B25B 17/02, publ. 01.04.1997), comprising a housing with a removable reaction support, inside the housing of which there is an annular gear, the first and second gears located inside the gear wheel and rotating around input eccentric shaft, pins, input eccentric shaft and output shaft.

Technical problem - the device has a complex structure to increase torque.

The problem in this utility model is solved by the fact that the arsenal of technical means is expanding with improved technical characteristics, namely the transmission of increased torque while maintaining the compactness of the device.

The technical problem is solved due to the fact that the device contains a housing with a horizontal plane of the connector, coaxial input and output shafts, two planetary gears installed in the housing and transmitting torque from the input to the output shaft, while the housing is configured to install a reaction support and the axles of the planetary gear satellites are mounted on parallel non-axial axes.

The principle of operation of the device.

дюйма. При вращении ручки приводится во вращение входной вал 4, который через нарезанную на входном валу шестерню передает крутящий момент первому планетарному механизму 7. Сателлиты первого планетарного механизма, обкатываясь по коронной шестерне, неподвижно соединенной с корпусом устройства, приводят в движение водило второго планетарного механизма 8. Водило второго планетарного механизма, сателлиты которого обкатываются по коронной шестерне второго планетарного механизма, передает крутящий момент выходному валу 6. Выходной вал имеет выходной квадрат 1

дюйма, на котором устанавливается необходимая для работы торцевая головка или любое другое устройство. Реакционная опора 5 устанавливается на стакане 1 корпуса.The handle of the drive (not shown in the drawings) of the multiplier is fixed on the input shaft 4 through the input square

inches. When the handle is rotated, the input shaft 4 is rotated, which transfers the torque to the first planetary gear via a gear cut on the input shaft 7. The satellites of the first planetary gear, rolling around the ring gear, fixedly connected to the device’s body, drive the carrier of the second planetary gear 8. The carrier of the second planetary gear, the satellites of which are driven around the crown gear of the second planetary gear, transmits torque to the output shaft 6. The output shaft has an output hydrochloric square 1

inch, which is installed necessary for the work of the socket head or any other device. The reaction support 5 is installed on the glass 1 of the housing.

Thus, there is amplification and transmission of torque from the input shaft 4 to the output shaft 6 with a gear ratio of 25: 1.

The tightening force is 6000 n / m. The overall dimensions with the reaction support removed are as follows: the length of the device is 360 mm, the width is 120 mm, the height is 255 mm, the mass of the reaction support is 4 kg, and the mass of the device is 10.6 kg.

The housing of the device can be made of steel and closed with a cover 3 using screws 10 located around the circumference. Under the cover there is a locking ratchet 9, presented in the form of a spring, which must be tightened before the force to twist or unscrew is directed to the bolt. The locking ratchet provides the spring load and ensures that the input tightening torque is directed directly to the bolted connection. The planetary gears are mounted on needle bearings.

The resource of the claimed device is 60,000 hours, an average service life of 8 years.

Thus, the claimed utility model provides an expansion of the arsenal of technical means with improved technical characteristics and a simultaneous increase in torque while maintaining the compactness of the device.
