Rotary Table Bearing Lubrication Through Integrated Oil Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rotary table devices require regular maintenance for grease lubrication of bearings, which is burdensome for operators, as the lubricating oil does not effectively reach the bearing in conventional horizontal rotary table devices with a vertical main shaft axis.
Innovation Solution
A communication passage is integrated into the frame to connect the space and accommodation space, allowing lubricating oil to flow and lubricate the bearing, eliminating the need for grease lubrication by ensuring the oil reaches the bearing through strategically placed communication passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If grease lubrication is used for the bearing, then the bearing can be lubricated without requiring oil circulation, but regular maintenance for grease replenishment is required which burdens operators
Solution Approach 1:
The bearing lubrication system is designed to automatically replenish itself using the oil circulation system. The oil supply passage delivers lubricating oil directly to the bearing, and the oil returns to the storage space through the return passage, creating a self-sustaining lubrication system that eliminates manual grease replenishment
Solution Approach 2:
The invention uses a hydraulic oil circulation system where lubricating oil is pumped from the storage space, delivered through supply passages to the bearing, and returned through return passages to the storage space. This hydraulic system automatically provides continuous lubrication without manual intervention
2Strength
If the bearing is provided between the lower surface of the table and the upper surface of the frame, then the table can be supported with respect to the frame, but the lubricating oil cannot reach the bearing in conventional horizontal rotary table devices
Solution Approach 1:
The invention introduces oil supply passages and return passages as intermediary channels to connect the oil storage space with the bearing. These passages act as mediators to deliver lubricating oil to the bearing location and return it to the storage space, solving the problem of oil delivery to the bearing in the horizontal rotary table configuration
Solution Approach 2:
The invention adds a new dimensional aspect to the lubrication system by creating a three-dimensional oil circulation network with supply passages extending to the bearing location and return passages bringing oil back to the storage space. This spatial arrangement enables lubrication in the horizontal rotary table configuration where conventional oil levels cannot reach the bearing

AI summary
A rotary table device includes a table provided on one end-side of a main shaft rotatably supported in a frame; and a drive transmission mechanism transmit rotation of an output shaft of a drive motor to the main shaft and including a drive transmission member and accommodated in an accommodation space formed in the frame. The table is supported with respect to the frame by a bearing provided between a lower surface of the table and an upper surface of the frame, and a space is provided between the lower surface of the table and the upper surface of the frame. The frame is provided with a communication passage configured so that the space and the accommodation space communicate with each other.
