Air Compressor Transmission Mechanism With Bearing-Locked Torque Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressor transmission mechanisms experience reduced air compressing efficiency and shortened service life due to deformation of plastic bases at high temperatures and improper engagement of the piston and bearing, leading to idle rotation and friction issues.
Innovation Solution
A transmission mechanism where the piston is rotatably connected to the torque gear, accommodated within the central orifice, and secured using a screw bolt that engages with the bearing, preventing removal and allowing smooth reciprocation without friction between the toothed portion and the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the base is made of plastic material, then the manufacturing cost is reduced, but the base softens at high temperature causing deformation and reduced air compressing efficiency
Solution Approach 1:
The base structure is segmented into two distinct parts: the main base body remains plastic for cost-effectiveness, while the receiving orifice is separately manufactured from heat-resistant material and integrated into the base. This segmentation allows each component to be optimized for its specific functional requirements without compromising the overall cost advantage.
Solution Approach 2:
The base assembly becomes a composite structure combining plastic material for the base body with heat-resistant material for the receiving orifice. This composite approach allows the structure to simultaneously achieve low cost (from plastic) and high temperature resistance (from heat-resistant material), resolving the contradiction between manufacturing cost and reliability.
2Productivity
If the piston moves reciprocately in the conventional setup, then the air compression function is achieved, but the piston causes idle rotation of the post and deformation of the bearing
Solution Approach 1:
The bearing is introduced as an intermediary component between the post and the receiving orifice. This bearing mediates the interaction by providing a proper bearing surface that supports the post's rotation without causing idle rotation or deformation, while still allowing the piston's reciprocating motion to drive the air compression function.
Solution Approach 2:
Instead of allowing the piston to directly drive the post through the receiving orifice wall (which causes deformation), the invention inverts the approach by providing a dedicated bearing structure that properly supports the post. The post rotates within the bearing rather than the bearing deforming under the post, reversing the harmful interaction.
3Device complexity
If the receiving orifice accommodates both the bearing and the driven gear, then the structural integration is achieved, but the driven gear fractions the inner wall causing piston offset and broken components
Solution Approach 1:
The receiving orifice structure is segmented to provide distinct functional zones: one area for the bearing to support the post, and another area for the driven gear to mesh with the drive gear. This segmentation prevents the driven gear teeth from interfering with the bearing installation and eliminates the fractioning of the inner wall, maintaining component integrity while achieving structural integration.

AI summary
A transmission mechanism of an air compressor (2) contains: a piston (54), a torque gear (57), a connection rod (53) rotatably connected with the piston (54), a cylinder (4) configured to accommodate the piston (54), wherein a central orifice (510) of the torque gear (57) corresponds to an internal ring (62) of a bearing (6) in a second positioning orifice (32) of a base (3), and a screw bolt (52) is inserted through the torque gear (57) to screw with the central orifice (510) from the internal ring (62) of the bearing (6), such that the torque gear (57) matingly contacts with the bearing (6) along the screw bolt (52), and the bearing (6) is not broken, thus moving the piston (54) in the cylinder (4) stably.
