15-tooth rubber couplings
Definition
15-tooth rubber couplings connect the engine and hydraulic pump. They are round and have 15 teeth spaced around the edge. Each tooth fits into a slot on the pump or engine. The main part is made from strong rubber. This makes the coupling both flexible and tough. The design helps it handle twisting and small mistakes in alignment.
Here is a quick overview of the main features:
Feature | Description |
|---|---|
Tooth Count | 15 |
Application | Yanmar VIO70/75/80, Komatsu PC70FR‑1 excavators |
Material | High-quality rubber for durability and vibration damping |
Maintenance | Plug-and-play compatibility for easy installation and reduced downtime |
These couplings fit certain mini-excavator models. They use strong rubber so they last a long time.
Function in pump drives
When you start your mini-excavator, the engine makes power. The 15-tooth rubber couplings move this power to the hydraulic pump. The rubber helps absorb shocks and cuts down on vibration. This makes the machine run quietly and smoothly. If the engine and pump are not lined up, the coupling still works well. Its flexible design helps protect both the engine and pump from harm.
You can fix things faster with these couplings. The plug-and-play design lets you change them quickly. This means your equipment is not out of use for long. Your pump drive will last longer and work better.
YNF Rubber is a top maker and seller of these couplings. You can count on their products to work well for your equipment.
Performance benefits
Power transfer
You want your mini-excavator to work hard every day. The power from the engine must move smoothly to the hydraulic pump. 15-tooth rubber couplings help you do this. The teeth on the coupling fit tightly with the engine and pump. This tight fit lets you transfer power without slipping. The strong rubber material holds up under pressure. You get steady power, even when the machine works in tough conditions.
When you use 15-tooth rubber couplings, you protect your pump drive. The rubber teeth grip well and do not wear out quickly. You do not lose energy between the engine and the pump. This means your mini-excavator can lift, dig, and move with full strength. You finish your work faster and with less trouble.
Tip: Always check your coupling for signs of wear. A good coupling keeps your machine running at its best.
Vibration absorption
Machines shake when they work. Too much vibration can damage parts and make your mini-excavator noisy. 15-tooth rubber couplings absorb these shakes. The rubber acts like a cushion. It takes in the shocks from the engine and stops them from reaching the pump.
You will notice less noise and smoother movement. The coupling keeps the hydraulic system safe from sudden jolts. This helps you avoid leaks and other problems in the pump. Your machine feels easier to control, and you do not get tired as quickly.
Less vibration means:
Quieter operation
Longer life for your pump and engine
Fewer repairs
YNF Rubber designs these couplings with high-quality rubber. Their focus on innovation gives you better anti-vibration solutions. You get a product that lasts longer and works better in real-world jobs. When you choose YNF Rubber, you choose a company that cares about your equipment’s performance.
Durability and maintenance
Service life
You want your mini-excavator to last as long as possible. The design of 15-tooth rubber couplings helps you reach that goal. The strong rubber material resists wear and tear, even when your machine works hard every day. The flexible teeth handle twisting forces and small misalignments. This means the coupling protects both the engine and the pump from damage.
When you use these couplings, you do not have to worry about sudden breakdowns. The rubber absorbs shocks and keeps the parts safe. You get more hours of work before you need to replace the coupling. This longer service life saves you time and money.
Maintenance needs
You can keep your equipment running smoothly with simple checks. The design of these couplings makes maintenance easy. You do not need special tools or skills. Regular inspections help you spot problems early and avoid bigger repairs.
Here is a table that shows how often you should check and maintain your coupling:
Maintenance Activity | Interval |
|---|---|
Thorough visual inspection | 2,500 hours |
Bolt torque inspection/recertification | 5,000 hours |
Complete coupling disassembly inspection | 10,000 hours |
You can see that you do not need to check the coupling very often. The long intervals show how reliable the design is. When you follow this schedule, you help your mini-excavator stay in top shape.
Tip: The coupling can handle small misalignments. This feature helps prevent damage to the engine and pump. You get fewer repairs and less downtime.
If you want the best results, choose a trusted supplier like YNF Rubber. Their products help you get the most out of your equipment.
Comparison with other couplings
Metal vs. rubber
You may wonder if metal couplings work better than rubber ones. Metal couplings feel strong and last in some machines. However, they do not absorb vibration well. When you use metal couplings, you often hear more noise. The machine may shake more, which can damage the pump and engine over time.
Rubber couplings, on the other hand, act like a cushion. They soak up shocks and reduce noise. Your mini-excavator runs smoother and quieter. You also protect your equipment from sudden jolts. This means fewer repairs and longer life for your pump drive.
Here is a quick comparison:
Feature | Metal Couplings | Rubber Couplings |
|---|---|---|
Vibration Absorption | Low | High |
Noise Level | High | Low |
Flexibility | Low | High |
Maintenance Needs | More | Less |
Note: YNF Rubber offers high-quality rubber couplings that help your mini-excavator perform at its best.
Tooth count differences
You might see couplings with different numbers of teeth. Some have fewer teeth, while others have more. The number of teeth changes how the coupling fits and works. Fewer teeth can mean less grip and more wear. Too many teeth can make the coupling stiff and hard to install.
15-tooth rubber couplings give you the right balance. The teeth fit snugly and spread the load evenly. This design helps your mini-excavator handle tough jobs without slipping or breaking. You get smooth power transfer and less stress on your pump drive.
If you want the best results, choose the 15-tooth design from YNF Rubber. You get a coupling that matches your machine’s needs and keeps it running strong.
Operator advantages
Reliability
You want your mini-excavator to work when you need it. 15-tooth rubber couplings help you reach this goal. These couplings handle small misalignments between the engine and pump. This means you do not have to worry about shafts lining up perfectly every time. The flexible rubber design absorbs shocks and vibrations. Your machine runs smoother, and sensitive parts stay safe from sudden jolts.
You also get better load distribution. The coupling spreads the force evenly across all teeth. This reduces stress on any single part. You see fewer breakdowns and less unplanned downtime. Your mini-excavator stays ready for work, even in tough conditions.
