轴承杯

Bearing cups are precision-machined housings that support and align bearings in cross/yoke assemblies for smooth rotational motion.

技术定义与适配语境
典型 轴承杯 会按材料、尺寸公差、适配关系和失效风险在 汽车制造 中评估。

Bearing cups are critical components in cross/yoke assemblies, serving as outer races or housings that contain and position rolling-element bearings (typically needle or roller bearings). They provide structural support, maintain bearing alignment under load, protect bearings from contaminants, and facilitate lubrication. In universal joint applications, bearing cups enable the articulation of drive shafts while transmitting torque efficiently.

定义
Bearing cups are critical components in cross/yoke assemblies, serving as outer races or housings that contain and position rolling-element bearings (typically needle or roller bearings). They provide structural support, maintain bearing alignment under load, protect bearings from contaminants, and facilitate lubrication. In universal joint applications, bearing cups enable the articulation of drive shafts while transmitting torque efficiently.
工作原理
Bearing cups work by providing a hardened, precisely machined surface for bearing elements to roll against, distributing radial and axial loads evenly across the bearing assembly. They maintain concentricity and preload, reducing friction and wear while allowing controlled movement in mechanical linkages.
材料
Typically made from case-hardened alloy steels (e.g.AISI 86204140) or through-hardened steels (e.g.52100). Surface hardness: 58-64 HRCcore hardness: 28-35 HRC for toughness. May include corrosion-resistant coatings like zinc plating or phosphate treatments.
Width
12-40 mm
Bore Diameter
10-50 mm
Load Capacity
Dynamic: 5-50 kN, Static: 10-100 kN
Outer Diameter
15-70 mm
Surface Finish
Ra 0.4-0.8 μm
Operating Temperature
-40°C to +120°C
标准
ISO 15DIN 620

常见问题

What is the primary function of a bearing cup in a cross/yoke assembly?

The bearing cup houses and supports bearings, maintaining alignment and distributing loads to enable smooth rotational motion in universal joints.

How do I select the right bearing cup for my application?

Consider load capacity, speed, environmental conditions, material compatibility, and adherence to standards like ISO or DIN. Match dimensions and hardness to bearing specifications.

Can bearing cups be reused after bearing failure?

Generally not recommended. Wear, scoring, or deformation from previous use can compromise performance. Always inspect and replace if any damage is detected.
