Product Description

The flat key pin is a fundamental component in mechanical systems, acting as the linchpin in mechanical transmission. It serves the critical purpose of ensuring circumferential fixation between the shaft and hub, effectively transmitting torque and motion. Below is an in-depth look into its structure, working principle, characteristics, application scenarios, usage methods, and essential precautions.

• Structure: With elegant simplicity, this component is fashioned in the shape of a flat rectangular prism, comprising a head and a key body. The head is available in three distinct forms: circular (Type A), square (Type B), and round (Type C). The key body's sides are the operational surfaces, meticulously designed to fit snugly against the keyway sides of both the shaft and hub, while its bottom surface aligns perfectly with the bottom of the hub and shaft keyway.

Working principle: During assembly, the flat key pin is gracefully inserted into the shaft's keyway. The hub, equipped with a matching keyway, is then seamlessly mounted onto the shaft. This positioning ensures the flat key pin is perfectly situated between the shaft and hub keyways. Functionality is achieved through the frictional forces generated by compression, allowing torque to transmit smoothly, ensuring the harmonious synchronous rotation of the shaft and hub.

• Characteristics

Simple structure: Boasting simplicity, its regular shape and mature processing technology make manufacturing straightforward and cost-effective, enabling easy and large-scale production and application.

Easy disassembly and assembly: Designed for simplicity, it fits directly into the keyway upon installation and can be removed without complex procedures, facilitating effortless equipment maintenance and component swaps.

Good neutrality: Maintains impeccable relative positioning between the shaft and hub, ensuring smooth transmission and ideal for systems demanding high concentricity.

Wide applicability: Universally adaptable, it connects various shaft and hub types, making it a staple in diverse mechanical transmission apparatuses.

• Application scenarios

Motor manufacturing: Employed to connect motor shafts with pulleys and couplings, ensuring the motor's torque is reliably transmitted to the load with optimal efficiency.

Reducer: Critical in channeling power and upholding transmission precision between the reducer's gear shafts and gears at different levels.

Machine tool equipment: Links machine tool spindles with tools, chucks, and more, securing precise power transmission and masterful motion control.

Automotive manufacturing: Essential for linking the crankshaft and flywheel in automotive engines, as well as the transmission's input shaft and gears.

• Instructions for use

1. Specification selection: Choose the appropriate flat key pin size and type by considering shaft diameter, torque magnitude, hub size and structure, and adhering to relevant standards (e.g., GB/T 1096).

2. Keyway processing: Process the keyway on both shaft and hub precisely, matching the dimensions of the chosen flat key pin, ensuring compliance with design specifications for width, depth, length, and surface finish.

3. Install the flat key pin: Begin by clearing the keyway of debris, delicately insert the pin into the shaft's keyway, ensuring tight contact with the shaft groove's base. Align the hub's keyway with the pin, steadily seating it onto the shaft, ensuring seamless entry into the hub's keyway.

• Precautions

Tolerance fit: Meticulously control the tolerance fit accuracy between the flat key pin and keyway. A loose fit may lead to instability and slippage, while excessive tightness could hinder installation and damage components.
