Introduction

It is not wrong to say that time is money in big industries. To save the valuable time in our industries and vehicle racing cars. We will try to introduce a new thing that is four nut opener with size adjuster .It is a device that used in automobile for opening nut of wheel simultaneously. As in car racing the time is most important factor so by using this device we can reduce consumption of time in changing of tyre.This device can also used in industry to mount a new tyre at minimum time . The most important thing is that it can used for varying BCD(Bolt circle dia.) and no.of cars. BCD ,the dia on which a wheel nut is mounted. By using such device we will open all nuts simultaneously.

Working

The working of this device is so simple. As the input power given to the sun gear by means of manual or automation. It will transmitted to the planet through sun gear . As the sun revolve the planet ,it cause revolution of spanner spindle .This spanner spindle attached to car wheel nut and nut are open by the screw. As per requirement, all the car BCD are not same so we have to change the BCD of device also. To perform this function the sun has straight bevel gear at particular angle. As the BCD of tyre wheel change the movement of planet on the sun gear help in achieving required BCD . In this way we can perform the function of opening of all four nut of car wheel . By doing this we can achieve the high productivity.

RE: FOUR NUT OPENER ppt
Most trucks have lug nuts set at around 500 foot pounds of torque. It is very difficult to generate this kind of power alone, even if you have a cheater bar and a sturdy wrench. But with the Cheater Wrench, you can multiply your torque at a 78:1 ratio, meaning you can generate upwards of 5,000 foot pounds of torque! That's easily enough to remove any lug nut from any truck. Other torque multiplier lug nut wrenches are not as powerful and come with weak one year warranties. We are so confident in the Cheater Wrench that we provide a full lifetime warranty. If it breaks removing any lug nut, just send it back and we will replace it. Just remember, you cannot use an impact gun with the Cheater Wrench. Only spin the input shaft with the handle provided to keep your Cheater Wrench working smoothly and removing any hard to break lug nut.

Adjustable Multinut wheel opener is a special purpose tool
made to open/close all the nuts of a wheel in one time with less
effort. Although various methods are used for opening nuts, they
require a lot of effort to open a single nut. The main objective of
work is to develop a single tool with multiple mechanisms,
which can be made use during assembling and dismantling of
wheels in automobiles. It can be successfully used as a standard
tool irrespective of the model of the vehicle. Also it can be used
in assembly line of automobiles, garages, workshops and service
stations.
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
bevel gear to transmit relative motion to other gears. Generally
bevel gears are used for transmitting power between non parallel
intersecting shafts. So bevel gear arrangement is used for
actuating the four socket spanners at a time. Twelve driven gears
and one pinion gear are used. The cam and follower mechanism
is used for making the project adjustable. For this purpose radial
cam is used because the follower moves in the direction
perpendicular to the cam axis. And spherical face follower is
used because the side thrust and wear is considerably low. The
pinion gear is meshing with four auxiliary gears which are in turn
connected to a gear whose axle containing the socket spanners at
its end. The auxiliary gear connected to a hollow shaft (main
shaft) which is acting as a guide for follower. The other end of
the follower is connected to a bevel gear. A lock nut arrangement
is provided for connecting the main shaft to follower at any
desired position.

The adjustable wheel opener is a special tool made to open / close all the nuts of a wheel in one go with less effort. Although several methods are used to open the nuts, they require a lot of effort to open a single nut. The main objective of the work is to develop a single tool with multiple mechanisms, which can be used during the assembly and dismantling of wheels in automobiles. It can be used successfully as a standard tool regardless of the vehicle model. It can also be used in assembly line of cars, garages, workshops and service stations.

In general bevel gears are used to transmit power between parallel non-intersecting axes. Therefore, the bevel gear arrangement is used to drive the four socket wrenches at a time. Twelve driven gears and a pinion are used. The cam and follower mechanism is used to make the project adjustable. For this purpose a radial cam is used because the follower moves in the direction perpendicular to the axis of the cam. And the spherical face follower is used because the lateral thrust and wear is considerably low. The pinion gear is meshed with four auxiliary gears which in turn are connected to a gear whose shaft contains the plug pins at its end. The auxiliary gear is connected to a hollow shaft (main shaft) which acts as a guide for the follower. The other end of the follower is connected to a bevel gear. A safety nut arrangement is provided to connect the main shaft to the follower in any desired position. When the pinion is turned, the auxiliary gears are also rotated which, in turn, give a rotating movement to the socket wrench. This helps tighten or loosen the screws. The adjustment to remove the bolts having different pitch circle diameter is achieved by turning the cam. The followers are in contact with the cam when the cam is turned, the follower will move linearly. After reaching a desired position, the follower is locked with the hollow shaft to rotate them as a single axis. The cam is then put back in its initial position to prevent the cam from getting severely worn while the follower is rotating.
