3115531400 安百拓联轴器 3115 5314 00 驱动器 阿特拉斯·科普柯凿岩机 COP1638HD

Tough Driver Coupling. Less Energy Lost Between Piston and Bit.

The 3115531400 driver sits between the piston and the shank adapter on Atlas Copco COP 1638HD+, 1838+, and 2238HD+ rock drills. It's a sintered steel part, induction hardened, that takes repeated high-frequency hits and passes that force through without eating it up. The contact faces are ground smooth to keep friction low, which helps you hold consistent penetration rates in hard rock. When the driver wears, your drill loses punch and the steel takes more punishment. This one is made to keep the shock train efficient for more meters between teardowns.

Highlights
Key Advantages
  • Fits straight in on Atlas Copco COP 1638HD+, 1838+, 1838HD+, 1838HE+, 1838MUX+, 2238HD+ – no shimming, no modifying.
  • Sintered steel body, induction hardened to 58–62 HRC. It doesn’t mushroom or spall under normal high-cycle impact loads.
  • Contact geometry matches the piston face and shank adapter profile. Energy passes through without spreading sideways, so the drill string gets the hit, not the housing.
  • Ground and polished on bearing surfaces. Less drag means the rotation unit works easier and you don’t scuff the mating part.
  • Proven in headings, benches, and foundation bores where operators run long shifts and don't want to swap parts every week.
Use Cases
Applications
  • Underground development and production drilling with COP hydraulic drifters on jumbos
  • Tunnel face drilling where consistent penetration and low vibration matter shift after shift
  • Quarry and construction bench drilling – anchors, foundations, piped bedding
  • Heavy-duty surface drilling rigs working abrasive ground with COP 1838+ or 2238HD+ hammers

3115531400 驱动器 阿特拉斯·科普柯
3115531400 驱动器 阿特拉斯·科普柯是一款精密工程部件，专为阿特拉斯·科普柯液压和气动钻井系统中的最佳扭矩传递、机械稳定性和长期耐用性而开发。作为凿岩机冲击机构的关键元件，该驱动器确保从活塞到冲击元件的精确能量传递，最大限度地减少能量损失，同时最大化钻井功率和一致性。

按照原始设备制造商精确尺寸制造，3115 5314 00 驱动器 阿特拉斯·科普柯可与阿特拉斯·科普柯凿岩机和钻孔机无缝兼容。它是维持采矿、隧道施工和建筑行业钻井机械运行完整性的必备备件。

3115531400 驱动器 阿特拉斯·科普柯的功能与应用

能量传递中的核心作用

3115531400 驱动器 阿特拉斯·科普柯 用作活塞与钻柄适配器之间的联轴部件。其设计旨在通过直接接触面高效传递冲击能量，确保在钻井过程中动能损失最小。这样可确保稳定的钻进速度，并减少整个冲击系统的磨损。

在高性能凿岩机中，即使驱动器几何形状的微小缺陷也可能导致不对中和能量效率低下。因此，该驱动器的精密设计和硬化表面对于平稳、强劲和精确的钻井操作至关重要。

在重型机械中的应用

3115 5314 00 驱动器 阿特拉斯·科普柯 广泛用于各种在苛刻条件下运行的阿特拉斯·科普柯钻机和钻车，如：

  • 井下采矿和隧道施工

  • 采石和建筑基础钻孔

  • 露天作业

  • 液压和气动凿岩机系统

它作为稳定和驱动接口，保持旋转精度并提供连续扭矩，无机械打滑或振动。

FAQ
FAQ
Is this driver a direct fit for my COP 1638HD+?
Yes. It matches the OEM dimensions and hardness spec for COP 1638HD+, as well as the 1838+ series and 2238HD+. You pull the old one, clean the seat, slide this in, and go back to drilling.
How can I tell if my current driver needs replacing?
Look for pitting on the impact faces, mushrooming at the edges, or a drop in drilling speed with no other obvious cause. Also check if the shank adapter shows uneven wear. A worn driver absorbs energy instead of passing it, so your bit doesn't get the full hit.
What material is the 3115531400 made from?
It's a sintered steel alloy, through-hardened then induction hardened on the wear surfaces up to 58–62 HRC. That gives a tough core and a hard skin that doesn't crack or spall under repetitive impact.
What's the usual lead time for this part?
We keep these in stock whenever possible. Typical shipping is 1–3 working days after order confirmation. If we're backordered, expect 2–4 weeks. Send us your quantity and location, we'll give you a firm date.
Is this a genuine Epiroc part?
We supply OEM-spec parts built to the same drawings and heat-treat recipes that Epiroc uses. You get the same hardness, the same profile, and the same service life without the premium brand markup.
