What is Ratchet Gear?
Ratchet Gear is a specialized type of device that can only turn in one direction. Most Ratchet gears have teeth that are round on one side and on the other. The part of Rohatka, which interacts with the gear called the latch, slips across the rounded side, but will be caught on the flat side. This one -way rotation causes Ratchet Gears to be suitable for tasks that require discrete points, such as clicking on the dial. Unlike many one -way gearbox systems, horns allow a small amount of backward movement; This makes them better for restless applications where the slip does not cause damage.
Ratchets are actually very simple mechanisms. They usually consist of three parts: Ratchet Gear, latch and shaft. The gearbox sits at the end of the shaft and the shaft is either solid or able to spin. Zápaw sits next to the gear, often with a small spring that pushes the latch points into the rags. When the gear turns around, the latch movesIt yields through the rounded part of the teeth and clicks on the flat side, which provides their unique clicks of the Roste.
Another one -way gearbox, such as screw gears, is unable to move backwards. This is not entirely true for Ratchet Gear. Between clicks - that's, after the latch clicks on one tooth, but before clicking on the next - Ratchet can turn in both directions. This amount of movement is very small, but can be significant depending on the purpose of the device. As a result, horns are more common in human -powered tools.
The most common hand -driven ROHATka is in the key key. These horns have fixed devices and shafts that connect to the socket. The handle and latch are connected but separate from the device. When the user turns the key in one way, the head resistance in the socket causes the swollen to move freely. When Tourned vice versa, ZapaDKA pushes against the gear, moves the power generated into the screw and screws it in.
Most socket keys have a switch that changes the direction of Rocatka. Although there are several ways to design the socket key, the most common method uses the second set of Ratchet Gear. When the switch moves to the second position so that it can pull out the screw, the latch moves to the second gear that has teeth from the first reversal. The internal process works in the same way; The key is unscrewed instead.
