Description
Technical field
The present invention relates to a kind of shaft coupling technology, specifically a kind of heat transfer for substantially reducing drive shaft and driven between centers
Self cooled shaft coupling.
Background technique
In high-temperature flue gas forced discharge system, exhaust fan long-term work is in hot environment, this is to the electricity for driving exhaust fan
Machine proposes very harsh condition: the drive shaft of exhaust fan is usually metal, it is the good conductor of heat, can be directly by high temperature
Conduction is to inside motor, and motor is driven by enamel-cover line winding group, and heatproof is limited, is isolated if do not done, and will be unable to using being
Motor used in this high-temperature flue gas exhaust fan having has done many specially treateds, causes motor volume very big, weight is very heavy, and cost is big
Increase, the motor as used in water heater exhaust fan.There is relatively good method that the high temperature of exhaust fan is isolated? so not only
Ordinary motor can be used, and overall cost can be greatly reduced, by searching for the relevant technologies and patent, without referential side
Case.
Summary of the invention
The object of the present invention is to provide a kind of shaft couplings that self cooling is realized by itself high speed rotation, by that will drive
Axis be directly connected to be converted into radial transition to outer ring after connect, the heat through radially connected conduction is made because of whole high speed rotation
It is quickly dissipated to surrounding and realizes automatic cooling, so that motor holding be made to work at a lower temperature.
To achieve the above object, according to an aspect of the invention, there is provided full symmetric spoke type structure, the spoke
The outer ring two sides axial direction junction connected, and the central axle sleeve connected is then two parts symmetrical and that angle is staggered, respectively
Connect driving shaft and driven shaft.
The spoke structure, the axis relative to center are full symmetric dynamically balanced structures, theoretically driven shaft
Point-blank with driving shaft, Chong Die with center axis.
The thermally conductive pathways of the spoke structure are oriented to couplings outside lane, then edge from side center along spoke direction
Outer ring circumference is oriented to other side center spoke, and from the side spoke surrounding guiding centre set, such heat transfer distance substantially increases
Add, radiates on the way faster.
The spoke structure and driving shaft and driven shaft synchronous rotary, outmost turns linear velocity is high, and heat dissipation is obvious.
For further isolation conduction, outer ring can be decomposed into two symmetric parts: the portion connecting with driving shaft spoke
Point and the part with driven axis connection, be isolated between two parts with heat-insulating material, but to ensure that stable connection is reliable, along axis pair
Claim and have dynamic balance structure, there can be no fall off.
In order to strengthen air cooling effect, the fan balde structure of tilt angle is can be used in spoke, can be rotated by the blade
When generate wind, further cool down driving motor.
Compared with the prior art, the invention has the advantages that:
Heat transfer distance is increased by spoke structure, expands radiating area and air-cooled effect, drops axial heat transfer significantly
It is low.
Detailed description of the invention
Fig. 1 is the cross-sectional view of one basic structure of the embodiment of the present invention
Fig. 2 is the schematic diagram of two basic structure of the embodiment of the present invention
Specific embodiment
The circular ring structure of 6 spokes of band is set in embodiment one: Fig. 1, outer ring is linked together with 6 spokes, at symmetric configuration,
Central area is divided into 2 parts: 3, left side spoke spaced apart is fixedly connected with left side center, A-A as shown, 3, the right spoke
Item is fixedly connected with the right center, B-B as shown.
Due to 6 spokes relative to center axis direction be it is full symmetric, there is dynamic balance structure, be suitable for high speed
Rotary motion.
Fastening screw or other fixed forms can be used in the fixation of driving shaft and driven shaft and shaft joint center.
Welding structure can be used in spoke and center, and shaft coupling is made to form monoblock type list part.
The advantages of this programme is that metal plate punching part can be used in spoke structure, low in cost.
It is made of in embodiment two: Fig. 2 three components, A-A section view graph structure in such as embodiment one of component 1, component 3 is strictly according to the facts
B-B section view graph structure in example one is applied, component 1 is connected among component 2 with the connecting shaft 2 of three symmetric configurations, is formed whole
Body connector.
Component 1 and component 2 be all in the axial direction it is symmetrical, there is dynamic balance structure, and component 3 is laid out along axisymmetrical,
Therefore the connector is along axisymmetrical and dynamic balancing on the whole.
Fastening screw or other fixed forms can be used in the fixation of driving shaft and driven shaft and shaft joint center.
The advantages of this programme is using after separated structure, and axial heat is only capable of conducting along several tie points, and at tie point
It in the state of running at high speed, can effectively carry out air-cooled, two-way that effect is thermally isolated is more preferable.
Above-described embodiment is only that the preferred embodiment of the present invention is described, not to the spirit and scope of the present invention
It is defined, under the premise of not departing from design philosophy of the present invention, professional and technical personnel in the art are to technical side of the invention
The various changes and modifications that case is taken, all belong to the scope of protection of the present invention.
