Precision improves while big reduction so that rapidly and accurately can be passed power at the time of cat ladder when being applied in stairmaster
It is defeated by each travelling mechanism in stairmaster.
In some embodiments, the afterbody of motor is provided with fan, fan and motor shaft coaxial design.Its advantage
It is that stairmaster often not only needs to transfer the weight of stairmaster in itself in cat ladder, it is also necessary to carries the weight such as personnel of wheelchair
Amount, therefore motor needs to provide a large amount of kinetic energy in a short time, produces many heats, the setting of fan can be realized in time will production
Raw heat sheds, and prevents from influenceing operation and the service life of motor.
In some embodiments, the afterbody of motor is provided with cover and covered, and cover lid is fan-shaped engraved structure, and cover housing is in fan
Outside.Its advantage is, while cover lid plays dustproof effect, the heat that fan is shed is diffused into outside motor in time,
And play a part of security protection, prevent fan that operating personnel are run at high speed is hurt from accident occurs.
In some embodiments, motor also includes bearing installing plate, bearing and connecting shaft, and bearing is installed installed in bearing
The center of plate, one end of connecting shaft is connected to the center of bearing installing plate and bearing abuts against, and fan is fixed on the connecting shaft
On, fan rotates around the connecting shaft.Its advantage is that convenient install bearing of the setting of bearing installing plate is fixed, and
Fan is fixed on bearing installing plate by connecting shaft, is coaxially disposed, and the stability of motion is more preferable, is connected firmly.
In some embodiments, the other end of connecting shaft is provided with location division, and fan is located at location division pacifies with bearing
Between loading board.Its advantage is that location division prevents from detaching connecting portion when fan from running at high speed, and can be preferably by fan
It is fixed on the outside of bearing installing plate and is radiated.
In some embodiments, bearing installing plate is provided with the fan-shaped engraved structure corresponding with cover lid.It is beneficial to effect
Fruit is that bearing installing plate also is provided with fan-shaped engraved structure, can be corresponding with cover lid, realizes the fan being arranged between
Timely and effectively diffusion to volume heat caused by motor internal.
In some embodiments, location division is one kind in bolt, locating rod or positioning convex.Its advantage
It is that can play a part of playing positioning while fixation is installed.
