Double Disk Brake Motor Housing Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radial brake systems in winches and hoists face limitations in brake performance adjustability and generate heat that causes thermal degradation of synthetic ropes, as the brake system is integrated into the drum, leading to inefficient heat management.
Innovation Solution
A double disk brake system integrated into a motor housing or drum support housing, featuring a disk brake with friction disks, input and output couplers, and a cam follower, which adjusts the brake pad size to enhance performance and dissipate heat through the motor housing, reducing thermal transfer to the rope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a radial brake system is integrated into the drum, then the brake system is compact, but heat is transferred to the rope through the drum causing thermal degradation
Solution Approach 1:
The brake system is extracted from the drum and relocated to the motor housing. The housing now serves as the heat dissipation structure, while the drum is freed from thermal exposure. This spatial separation eliminates the harmful heat transfer to the rope while maintaining compact integration within the motor housing.
2Device complexity
If a radial brake system is used, then the brake system is simple in structure, but brake performance adjustability is limited
Solution Approach 1:
The brake system incorporates an adjustable cam mechanism that allows dynamic modification of brake pad engagement characteristics. The cam profile and positioning can be adjusted to change the mechanical advantage and braking force, providing adaptability in brake performance without fundamentally altering the simple radial brake structure.
3Volume of moving object
If the brake system is integrated into the drum, then packaging is efficient, but heat management is poor
Solution Approach 1:
The motor housing acts as an intermediary heat sink and dissipation structure. By positioning the brake system within the motor housing, the housing's thermal mass and surface area serve as a mediator to absorb and dissipate brake heat away from the rope, improving heat management while maintaining efficient packaging.
