Jiaozuo brake

Brakes are a safety protection device mainly used to control the movement of machinery. When selecting a brake, it is necessary to choose the appropriate one based on its usage environment. There are many types of brakes, and when purchasing from a brake factory, how should we choose the product that is suitable for ourselves?

1： The selection of normally open or normally closed brakes is mainly based on the magnitude of braking torque, working properties, and working conditions. For example, the lifting and luffing mechanisms of lifting machinery must use normally closed brakes; For the operation and rotating mechanisms of various vehicles and lifting machinery, in order to accurately stop, it is necessary to control the torque and use normally open brakes.

2： Consider the size of the space used. For occasions with sufficient space, external block brakes can be used. Space is limited, and usually belt type, disc type, or inner shoe type brakes are selected.

3： Select the type based on the function and working requirements of the brake. The structure of hydraulic brakes is not complex, and hydraulic cylinders are the main executing components of hydraulic brakes. They are energy conversion devices that convert the hydraulic energy of liquids into mechanical energy to achieve linear reciprocating motion or reciprocating oscillation of the working mechanism. Hydraulic brake hydraulic cylinders have a simple structure and reliable operation, and are widely used in various mechanical equipment. In addition to being used alone, hydraulic cylinders for hydraulic brakes can also be combined with other mechanisms to achieve special functions. For mechanisms with high safety requirements, double brakes are generally installed to control the braking and separation of the power shaft through oil pressure, pressure relief braking, and pressure boosting separation

It can be used in both dry oil-free and wet oil-immersed environments

With manual release function, the friction plate can be manually released during pressure relief

Multi friction plate structure, long service life

There are many types of brakes, including service brake, disc brake, crane brake, electric hydraulic brake, etc., and different brake systems can play different roles. Let's take the service brake as an example and share with you the role it can play!

The motor is in a power generation state from time to time when parking or being dragged by a load. Simply put, it is in a power generation state when the speed is opposite to the torque direction. At this time, the motor will convert mechanical energy into electrical energy.

Assuming that the equipment controlling the motor can only absorb energy from the grid and cannot send it back to the grid, the motor brake is needed to consume some of the remaining energy.

When the brake motor is powered on, the motor and brake coil are energized together. At this moment, the magnetic disc of the brake overcomes the pressure of the tension spring and is attracted to the side of the magnetic pole group, causing the conflicting plate to detach from the brake plate, allowing the motor to start.

Two types of diagrams, YWZ4 and YWZ

When the power supply is cut off, the magnetic disc is pushed out by the tension spring due to the disappearance of the magnetic field, causing the conflict plate on the magnetic disc to collide with the brake plate, and quickly braking the motor. This series of products has good friction performance of the spindle brake, low braking spark, and no damage to the dual; Yaw noise free, good friction performance, and non damaging dual brake friction materials. The friction material brake friction material technology has reached the international advanced level through technical appraisal by the provincial scientific research department
