Product Description

The flat key pin, a pivotal mechanical component, is indispensable in mechanical transmission. It serves a crucial function by ensuring circumferential fixation between the shaft and the hub, proficiently transmitting torque and motion. Below is an in-depth exploration of its structure, working principle, characteristics, varied application scenarios, usage methods, and essential precautions.

• Structure: The flat key pin boasts a straightforward, streamlined structure, resembling a flat rectangular prism, and is comprised of a head and a key body. The head is versatile with three distinct shapes: circular (Type A), square (Type B), and round (Type C). The key body's sides act as working surfaces, snugly aligning with the keyway sides on both the shaft and wheel hub, and making contact with the hub keyway's bottom surface and the shaft keyway's bottom surface for optimal performance.

Working Principle: In the assembly process, the flat key pin is deftly inserted into the shaft's keyway, and the hub with its corresponding keyway is then fitted onto the shaft, positioning the flat key pin securely between the shaft and hub keyways. During operation, torque is transmitted efficiently as the key's side makes contact with the shaft and hub groove sides, relying on frictional force from compression to achieve synchronized rotation of the shaft and hub.

• Characteristics

Simple Structure: With its regular shape and established processing technology, the flat key pin is characterized by low manufacturing complexity and economical cost. It is perfectly suited for large-scale production and widespread application.

Easy Disassembly and Assembly: The flat key pin is user-friendly, as it can be easily inserted into the keyway during installation. Its design eliminates the need for complicated operations during disassembly, facilitating maintenance and component replacement.

Good Neutrality: Ensuring precise relative positional accuracy between the shaft and the wheel hub, the flat key pin provides smooth transmission, ideal for systems demanding high concentricity.

Wide Applicability: Versatile and adaptable, the flat key pin is suitable for diverse types of shaft and hub connections, finding extensive use across various mechanical transmission devices.

• Application Scenarios

Motor Manufacturing: The flat key pin is essential for connecting the motor shaft to the pulley and coupling, ensuring that the motor's torque is effectively transmitted to the load end with high efficiency.

Reducer: This component plays a critical role in transmitting power and ensuring transmission accuracy between the gear shafts and gears at all levels within a reducer system.

Machine Tool Equipment: Facilitating precise power transmission and motion control, the flat key pin connects the machine tool spindle to cutting tools, chucks, and various components.

Automotive Manufacturing: Commonly employed in connecting the automotive engine's crankshaft and flywheel, as well as the transmission's input shaft and gears, ensuring reliable performance.

• Instructions for Use

1. Specification Selection: Select the suitable size and type of flat key pin based on the shaft diameter, transmitted torque magnitude, and hub size and structure, while consulting relevant standards (e.g., GB/T 1096).

2. Keyway Processing: Accurately process the shaft and hub keyway according to the flat key pin's dimensions, ensuring the keyway's width, depth, length, and surface roughness meet design criteria.

3. Install the Flat Key Pin: Begin by removing debris and iron filings from the keyway. Carefully insert the flat key pin into the shaft keyway, ensuring firm contact between the key's bottom surface and the shaft groove. Align the hub keyway with the flat key pin and gently fit it onto the shaft, ensuring smooth entry into the hub keyway.

• Precautions

Tolerance Fit: Vigilantly control the tolerance fit accuracy between the flat key pin and the keyway. A loose fit could cause key loosening in the keyway, impacting transmission stability and potentially leading to slippage, whereas excessive tightness may complicate installation and cause damage to keys and keyways.
