gear calculation about multi nut remover
ABSTRACT
The main concept of the proposed system is nut fitting & removing without human help for driving. The heart of the project and implementation is motor. The components used here for efficient function of individual blocks are Motor, Nut fitting arrangement (spanner) and spur gear arrangement.The main objective of the model is to remove the nuts of a wheel at once and not one at a time. The principle of the model is the usage of spur gear to transmit relative motion to other gears. In the model, the primary spur gear is connected to the motor shaftwhich has rotational motion due to the motor. The driver gear is the primary gear and the driven gears are the secondary gears. The primary gear is placed on the centre of the model. The secondary gears are in mesh with the primary gear. The secondary gears are placed at calculated distance at the base plate to make prefect meshing and for the perfect spacing of the tool. A primary gear is attached to the drive axle. A plurality of secondary axles extends through the cover. Each of the secondary axles has a first end positioned within the housing and a second end extending outwardly away from the cover. Each of a plurality of secondary gears is attached to one of the first ends. The secondary gears are each in communication with the primary gear. Each of a plurality of couplers is attached to one of the secondary axles. The project and implementation has to give the positive & negative potential to the motor. If we push the corresponding switch for forward rotation, it helps to fix the nut, or else if we push the corresponding switch for reverse rotation, the given polarity will be changed oppositely and it helps to remove the nut. The motor can be operated according to the operator s requirement. The electric power can be given by the battery. The operator should lift the model and place at the appropriate place to tighten or remove the nut.
INTRODUCTION
Vehicle is an important machine in human daily life. Nowadays, each family has at least one car to make the transportation easy and faster. For a car, the tool set-up for each vehicle is a T-nut wrench and car jacker which is hard to use for a women or teen to open their car s nut. One of the problems of a vehicle is tire problem. If the vehicle tires have some problem then the user must remove the tires and fix the problem. And for a car user, it s difficult to remove tire s nut especially for women users. The obstacles are time waste and force needed. In Malaysia automotive market there is no tool that is easy to use to remove the nuts. The time to open a car s tire nut is too long and has waste
the car user s time with utilization of high force that is hard for women users. To resist the time waste and high force needed a tool have been designed to remove four tire nuts in one time with force used decrement.
