Изобретение относитс к машиностроению , в частности к гаечным ключам с различными приспособлени ми дл вращени гаек.The invention relates to mechanical engineering, in particular to wrenches with various means for rotating the nuts.

По основному авт. св. № 818850 известен инерционный гайковерт, содержащий корпус с руко ткой силовой привод с выходным валом, корпусной МСХ (механизм свободного хода), обгонна муфта, шпиндель с закрепленными на нем рабочим органом, планетарный редуктор, имеющий водило, сателлитные шестерни, выполненные неуравновешенными , установленные на водиле, жестко св занном со шпинделем и с внутренней обоймой корпусного МСХ, закрепленной на корпусе, а гайковерт снабжен размещенной на выходном валу привода солнечной шестерней, взаимодействующей с неуравновешенными сателлитными шестерн ми .According to the main author. St. No. 818850 is known an inertial nut wrench, comprising a housing with a handle, a power actuator with an output shaft, a hull-free MSH (free wheeling mechanism), an overrunning clutch, a spindle with a working body fixed on it, a planetary gearbox with carrier, satellite gears made unbalanced, mounted on the driver rigidly connected with the spindle and with the inner case of the hull-mounted hull-mounted clamp mounted on the case, and the wrench is provided with a sun gear located on the output shaft of the drive, which interacts with unbalanced gear wheels.

Недостатком известного гайковерта вл етс невысока точность параметров зат жки , низка производительность труда.A disadvantage of the known wrench is the low accuracy of the tightening parameters, low labor productivity.

Цель изобретени - повышение точности параметров зат жки и повышение производительности .The purpose of the invention is to improve the accuracy of the tightening parameters and increase productivity.

Поставленна цель достигаетс за счет того, что гайковерт снабжен выходным механизмом свободного хода, посредством которого водило планетарной передачи св зано со шпинделем.This goal is achieved due to the fact that the wrench is provided with an output free-running mechanism, by means of which the planetary gear carrier is connected with the spindle.

На чертеже изображена структурна схема гайковерта.The drawing shows the structural scheme of the wrench.

Гайковерт инерционный содержит корпус 1, в котором размещен электродвигатель 2, на вал которого посажена солнечна шестерн 3, взаимодействующа с неуравновешенными сателлитами 4, которые вращаютс вокруг осей водила 5. Водило 5 жестко св зано с внутренними обоймами корпусного и выходного 6 и 7 МСХ и устанавливаетс в корпусе I на подшипнике. Наружна обойма корпусного 6 МСХ жестко крепитс на корпусе 1. Наружна обойма выходного 7 МСХ жестко св зана со шпинделем 8.The inertial impact wrench contains a housing 1 in which an electric motor 2 is placed, on its shaft a sun gear 3 is fitted, interacting with unbalanced satellites 4, which rotate around the axes of the carrier 5. The carrier 5 is rigidly connected with the inner cages of the hull and output 6 and 7 MSH and is installed in the case I on the bearing. The outer casing of the hull 6 MSH is rigidly mounted on the housing 1. The outer yoke of the output 7 MSH is rigidly connected to the spindle 8.

Работа гайковерта инерционного осуществл етс следующим образом.The inertial wrench operation is performed as follows.

Claims

Solar shchestren 3, brought into rotation by the electric motor 2, rotates the unbalanced satellites 4. The centrifugal forces of the unbalanced satellites turn the carrier 5 into one or the other side, and the smaller the resistance on the spindle 8, the greater amplitude it will fluctuate, the less a cool moment is transmitted to the spindle. When the carrier is slowed down, the Vrus satellites come at maximum speed, the maximum centrifugal forces tend to turn the carrier 5, the maximum steepness, and the moment is transmitted to the spindle 8. In order to force the spindle to rotate in one direction, the pulses in the opposite direction should not be perceived. This is carried out with frame and output fur. The forward pulse closes on the spindle through the output MCX, while the inner race of the MCH rotates freely relative to the outer race. The reverse impulse closes on the housing 1 through the hull MCX, while the inner cage of the output MCX rotates freely relative to the outer one, i.e. the specified wrench has a continuously variable transmission, which allows to obtain an infinitely variable tightening speed of the threaded connections depending on the resistance moment and allows fully utilize the power of the drive motor. In addition, the required precision of tightening is achieved, labor productivity is increased. The formula of the invention inertial wrench according to ed. St. No. 8 8850 is distinguished by the fact that, in order to increase the accuracy of the tightening parameters and increase productivity, it is equipped with an output free-running mechanism, through which the planetary carrier is connected with the spindle.
