Is your device facing the following challenges?
The excavator bucket suddenly hits a rock, causing the transmission system to suffer a severe impact and leading to frequent damage to bolts and bearings?
Does the crusher frequently stall momentarily due to uneven feeding, causing the motor to overload and trip? Is production repeatedly interrupted as a result?
When the cold rolling mill bites into the steel billet, the load suddenly changes, accelerating wear on the transmission components and keeping maintenance costs persistently high?
If the above issues exist, the root cause often lies in: The power transmission link lacks effective buffering and protection. 。
As a leading manufacturer in the field of hydraulic transmission, Zhongxing Hydraulics will delve into the following question in this article: Why... Limited-torque hydraulic coupling (Especially Model YOX500 ) is a key component for addressing the pain points in the transmission systems of high-impact equipment such as excavators, crushers, and cold rolling mills.
I. Working Principle: From “Hard Against Hard” to “Soft Overcomes Tough”
Traditional rigid couplings directly transmit impact torque to the equipment, whereas... Limited-torque hydraulic coupling Then, a connection is established between the motor and the equipment. Hydraulic buffer unit It transmits power through the working fluid between the pump impeller and the turbine, thereby achieving three core functions:
Motor light-load startup The motor starts nearly under no-load conditions and then smoothly accelerates to full load, significantly reducing the inrush current and protecting both the motor and the power grid.
Automatic overload protection When the device freezes up or becomes overloaded, a slip occurs inside the coupler, limiting the output torque to a safe level and thereby protecting the motor and transmission components.
Absorb shock and vibration The hydraulic fluid medium effectively cushions shocks and vibrations at the load end, ensuring smoother transmission and significantly extending the overall service life of the equipment.
For heavy-duty equipment with severe load fluctuations, installing a suitably rated torque-limiting hydraulic coupling is a fundamental measure to enhance the reliability of the transmission system.
II. Core Selection Guide: Key Parameters of the YOX500 Hydraulic Coupler
As the original manufacturer, we ensure that technical specifications are transparent. The following are: YOX500 Limited-Torque Hydraulic Coupler The core technical data are an important basis for your accurate equipment selection:
| Parameter Item | Specific values/notes | ||
|---|---|---|---|
| Input speed and transmitted power | 1000 r/min: 25-50 kW 1500 r/min: 68–144 kW |
||
| Overload factor | Startup: 1.5–1.8 | Braking: 2-2.5 | |
| Transmission efficiency | Approximately 96% | ||
| External dimensions (mm) | D: Φ582 | A: 435 | A1: 316 |
| Shaft hole size (mm) | Maximum input/output aperture: Φ90 (length 170) | ||
| Oil capacity (L) | Minimum: 10.3 | Maximum: 20.5 | |
| Weight | 105.5 kg |
Parameter Interpretation and Application ：
Power matching With a power range of 68–144 kW at 1,500 rpm, it perfectly meets the requirements of auxiliary drive systems for medium-sized excavators, large crushers, and cold rolling mills.
Security Guardian A braking overload factor of up to 2–2.5 provides a quantified safety margin, enabling the equipment to withstand extreme impacts.
These precise parameters form the core foundation for the professional selection services provided by the original equipment manufacturer.
