Main Feature

• Brake linings are plug-in style, which are easy to replace.
• Interlocking shoes clearance balancing device and shoe auto-aligning device, constantly equalize the clearance of brake shoes on both sides and no need to adjust, thus completely avoid one side of brake Lining sticking to brake disc.
• Self-lubricating bearings are equipped at main hinge points, which bring high efficiency of transmission, long performance life and unnecessary to lubricate during the course of operation. The closing time is short (only 0.25-0.4s).
• Wear-self-compensation devices can realize self-compensation of shoes clearance and relatively constant brake torque It avoids the trouble of adjusting.
• Enclosed spring tube protects spring from damage and contamination.
• The Ed series thrusters are characterized by flexible action and long operating life.
• Brake closes in case of power failure (Fail-Safe Principle).Braking by spring power. Lifting by thruster.

 

Operating Condition

• Ambient temperature:-20℃~+50℃
• Relative humidity:air relative humidity is not more than 90%
• Voltages:AC 3 phase 380V,50Hz

    Also produces 60Hz or different voltages as needed, please indicate when ordering.

• Operating duty:Intermittent (S3-60%,1200 times per hour) and continuous(S1)
• Altitude in accordance with GB755-2019 of the place of use. When lower than -20℃ promoting the YH-10 aviation hydraulic oil instead of oil or belt as required and heat exchanger, for details refer to the Ed driver samples.
• Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion products.
• Special requirements can be discussed before production. 

 

Standards Compliant

• The braking torque parameters of YPZ₂I,II and III conform to the German standard DIN15433,while those of YPZ₂IV,V and VI conform to the German standard DIN15433 and JB/T7020-2006.
• They are equipped with Ed series thrusters which comply with DIN15430 standard.

FAQ:

Q1: What are the requirements for the brake disc when installing an YPZ2 brake?

A: The brake disc surface must be free from oil, rust, welding scars, or cracks. The end face runout should not exceed 0.15 mm for discs with a diameter ≤500 mm, and should not exceed 0.2 mm for discs with a diameter >500 mm. The typical surface roughness is 3.2 μm; excessively rough or overly smooth surfaces can both impair braking performance.

 

Q2: How to prevent the brake from seizing or failing to fit over the brake disc during installation?

A: Before installation, rotate the spring pull rod counterclockwise to reduce compression, and turn the connecting pull rod in the opposite direction to spread the two brake arms apart, ensuring the gap between the friction pads is 2–3 mm wider than the brake disc thickness. Take care that the pull rod does not detach from its inner sleeve, and never lift the brake by the pull rod to avoid deformation and sticking.
