LIMON is the manufacturer of linear motion products, ball screw is also our powerful product, which is interchangeable with TBI, we are not only produce right hand screw, but also left hand screw.
What is the difference between left and right hand ball screw？LIMON will answer your today.
What is left and right hand ball screw?
Ball screw is composed of screw, nut, steel ball, preloaded sheet, reverse device, and dust filter, which is the most commonly used in precision machinery. The ball screw is divided into a single arc, double arc according to the thread; According to the direction, there are left rotation, right rotation; According to the number, they were divided into single head, double head, multi head; According to the different spiral direction of the thread, the thread is divided into true buckle thread and reverse buckle thread. Its main function and great significance is to convert the rotational motion into linear motion. Besides, its has the characteristics of high precision, reversibility and high efficiency.
What is the difference between left and right hand ball screw?
Due to the different running direction of the lead screw and the different running direction of the equipment, there are left and right rotation of the lead screw production requirements. But this screw is only used in very special occasions, so the use is less.
left and right hand ball screw means the direction in which the screw rotates as it moves. The function of the screw is to convert rotational motion into linear motion, so the screw has a direction of rotation when operating on the machine. In general, the majority of left and right hand ball screw for a small amount, there are also right hand called forward, left hand called reverse. Because of low friction resistance, left and right hand ball screw is widely used in various types of industrial equipment and precision instruments.
How to distinguish left and right hand ball screw？
Screw orientation refers to the direction in which the screw thread is wound around its axis. Right-handed threads run clockwise and left-handed threads run counterclockwise. The origin of thread rotation is rooted in human physiology: whether a screw of different rotation is ergonomic depends on the dominant hand.
Today, most screws use right-handed threads, and it is difficult to find left-handed screws for applications that do not specifically require them. However, there are some applications that specifically require the use of left-handed ball screw.
Purpose and application of left and right hand ball screw
Sometimes, left-handed screws are implemented for the mechanical advantage of reverse threading. For example, some cars utilise left-handed threads on their left-hand wheels, which, unlike the wheels on the right, rotate anti-clockwise. This use of reverse-threaded fasteners prevents them from loosening gradually under the torque of the wheels. This particular use of left-handed screws is probably the most common, and is commonplace in products such as bicycle pedals, turnbuckles, or many types of machinery with a rotary blade.
Left-handed threads are also known as reverse threads. These threads are used in specialized applications in which the application of pressure would force a right-handed screw or bolt to come loose.
Some applications that benefit from the use of left-handed fasteners include:
- Automotive: Some tires’ bolts are reverse threaded to keep torque from loosening them
- Heating and plumbing: Pipes are often fitted with both right- and left-handed threads to provide an extra layer of defense from leakage
- Safety: Gas-supply valves use left-handed threads to differentiate them from the valves that control oxygen.
