KAIZEN
KAIZEN means improvement and continuing improvement in personal life, social life, home life, and working life. When applied to the workplace KAIZEN means continuing improvement involving everyone – managers and workers alike.
KAIZEN is a Japanese word meaning gradual and orderly, continuous improvement. The KAIZEN business strategy involves everyone in an organization working together to make improvements “without large capital investments”.
KAIZEN is a culture of sustained continuous improvement focusing on eliminating waste in all systems and process of an organization. The KAIZEN strategy begins and ends with people. With KAIZEN, an involved leadership guides people to continuously improve their ability to meet expectations of high quality, low cost, and on time delivery. KAIZEN transforms companies into ‘Superior Global Competitors’
Two Elements of KAIZEN
There are two elements that construct KAIZEN, improvement/change for the better and ongoing/continuity. Lacking one of these elements would not be considered KAIZEN.
For instance, the expression of “business as usual” contains the element of continuity without improvement. On the other hand, the expression of “breakthrough” contains the element of change or improvement without continuity. KAIZEN should contain both elements.
Basic Features For KAIZEN Activities
• Discarding conventional fixed ideas.
• Thinking of how to do it, not why it cannot be done.
• No place for excuses. Starting by questioning current practices.
• Less emphasis on seeking perfection. Doing things right away even if for achieving only 50% of target.
• Correcting it right away, if some mistake is made.
DESCRIPTION:
The rotary motion of the steering handwheel is changed to the linear motion of the drag link through the steering gear box & pitman arm. The drag link pulls & pushes the steering center level. So that this lever turns the right and left front wheels around their kingpins through the two tie rods and knuckle arm.
The whole system has a self restoring property & is designed for easy steering and high durability. The self restoring action is reliable the operating effort required for turning the hand wheel is small & the system components are easy to service. The rotary joints of the steering linkage are of ball & socket type. There are mainly three types of steering systems manufactured in Sona.
RECIRCULATING-BALL STEERING
Recirculating-ball steering -is used on many trucks and SUVs today. The linkage that turns the wheels is slightly different than on a rack-and-pinion system.
The recirculating-ball steering gear contains a worm gear. You can image the gear in two parts. The first part is a block of metal with a threaded hole in it. This block has gear teeth cut into the outside of it, which engage a gear that moves the pitman arm (see diagram above). The steering wheel connects to a threaded rod, similar to a bolt, that sticks into the hole in the block. When the steering wheel turns, it turns the bolt. Instead of twisting further into the block the way a regular bolt would, this bolt is held fixed so that when it spins, it moves the block, which moves the gear that turns the
wheels.
STEERING COLUMNS
The main function of steering columns is to provide the rotary motion of steering wheel to main steering assembly. One end of columns is connected with steering assembly. One end of columns is connected with steering assembly while the other end of columns is connected with steering hand wheel. There are two types of steering columns are manufactured in Sona.
