The main concept of the proposed system is the installation of nuts and elimination without human help for driving. The heart of the project and the implementation is engine. The components used here for the efficient function of the individual blocks are the motor, the arrangement of the nut lining (wrench) and the gear arrangement of the gearwheel. The main purpose of the model is to remove the nuts of a wheel immediately and not one at a time. The principle of the model is the use of the straight gear to transmit relative motion to other gears. In the model, the primary straight gear is connected to the motor shaft having rotational movement due to the motor. The driving gear is the primary gear and the driven gears are the secondary gears. The primary gear is placed in the center of the model. The secondary gears are meshed with the primary gear. The secondary gears are placed at a distance calculated on the base plate to make the gear perfect and for the perfect spacing of the tool. A primary gear is attached to the drive shaft. A plurality of secondary axes extends through the cover. Each of the secondary shafts has a first end located within the housing and a second end extending outwardly from the cover. Each of a plurality of secondary gears is attached to one of the first ends. The secondary gears are in communication with the primary gear. Each of a plurality of couplers is attached to one of the secondary shafts. The project and the implementation have to give the positive and negative potential to the engine. If we push the corresponding switch for forward rotation, it helps to fix the nut, or if we push the corresponding switch for the reverse rotation, the given polarity will be changed opposite and will help to remove the nut. The engine can be operated in accordance with the operator's requirements. The electric power can be given by the battery. The operator must lift the model and place it in the appropriate place to tighten or remove the nut.
Known power screw drivers which are driven by electric or pneumatic motors have a relatively high rotation speed to obtain a short screw-in time. Since the maximum tension moment for the screw to be screwed requires a certain torque, the driving power of the screwdriver must also be raised according to the relatively high rotation speed, although a high torque is required for only a short Time during tightening of the screw, unless some shock action is used in order to produce this degree of peak. The limitation of the degree of tightening of the screw is normally effected by means of ratcheting couplings or striking mechanisms. When screwing in expansion bolts, this tightening degree must be kept constant within very tight, since these screws, are tightened almost to their limit of elasticity during the screwing. Torque-sensitive screwing actuators having shock effects are useless for this purpose. The degree of tightening achieved depends to a large extent on the number of strokes applied, which however can not be kept constant due to the rapid succession of blows, while in addition the power of individual blow is variable within wide limits due to the indeterminable reaction of the Work Part, screw and screw tool in the striking operation. In addition, the impact effect causes a rapid wear on the impact surface, which results in a considerable variation of the face of the blows and a relatively short life of the screwdriver.
