Abstract
The invention provides a hardware connection structure for a permanent magnet synchronous motor. The hardware connection structure comprises a permanent magnet synchronous motor, a connecting shaft and a gear, which are sequentially connected, wherein the gear is connected with a synchronous belt taking a steel wire rope as a strength layer and coated by a polyurethane or neoprene ring-shaped belt; and the inner circumference of the synchronous belt is dentiform and is meshed with a tooth-shaped belt wheel. The hardware connection structure omits additionally calculating reduction gear ratio and torque calculation, adopts a manner of directly connecting with the gear to control on-off of a freezer door, has the advantages of small size, easiness in mounting, simple structure, convenience in maintenance and simplicity in debugging, without needing additional calculation, and is lower in requirements on mounting staff.
Description
Technical field
The present invention is applicable to machine field, relates in particular to a kind of hardware syndeton of permagnetic synchronous motor.
Background technology
Continuous progress along with society, can utilize freezer to solve Vegetable Preservation, and problem such as transportation, does but problem is freezer keep temperature again with for what? answer is exactly door--cold-storage door, it is AC asynchronous motor and DC Brushless Motor that cold-storage door now adopted more, these motor all exist a lot of problems, the motor that has can't be realized the adjustable of speed, the motor that also has can't be realized stable adjustable-speed, if want the deceleration device that adds of realizing that these functions so must be extra, could realize the switch motion of cold-storage door, complex structure is arranged, the failure rate height, the maintenance cost height, control precision is poor, shortcomings such as inefficiency can't satisfy the demand of high-grade freezer opposite house machine.
Summary of the invention
The invention provides a kind of hardware syndeton of permagnetic synchronous motor, select the ultrasonic wave Long-distance Control, with the cold-storage door control device that permagnetic synchronous motor drives, make simple in structurely, do not need additional deceleration device, dependable performance.
Purpose of the present invention is achieved through the following technical solutions:
A kind of hardware syndeton of permagnetic synchronous motor comprises the permagnetic synchronous motor, connecting axle and the gear that connect successively.
Be connected with synchronous band on the described gear, band is strength layer with the steel wire rope synchronously, outward coated with the endless belt of polyurethane or neoprene, and the dentation of the interior Zhou Weiyu gear engagement of being with synchronously.
Compared with prior art, the advantage of technical scheme of the present invention is:
Connected mode: the mode that current cold-storage door adopts asynchronous motor to add worm and gear more is controlled the motion of cold-storage door, type selecting, installation and debugging all bother very much, words with Induction Motor Control, at first need to calculate the value of moment when of slowing down, obtain selecting worm and gear to control again after the operation result, so just make installation volume very big, and install inconvenient; As the words that adopt permanent magnet synchronous motor to control, just do not need extra the calculating moment when of slowing down, adopt the mode that directly connects gear to control the open and close of cold-storage door, have only a motor to add a gear, overall volume is very little, installs also very convenient.
Control mode: prior art is to adopt chain to realize the motion of cold-storage door, utilize the control mode noise of chain bigger, get rusty easily, control precision is lower, the control mode of band solves the problems referred to above and adopt synchronously, band is to be strength layer with the steel wire rope synchronously, outward coated with the endless belt of polyurethane or neoprene, band interior week make dentation, itself and profile of tooth belt wheel are meshed.During band transmission synchronously, gearratio is accurate, and the control precision height is little to the axle active force, compact conformation, oil resistant, resistance to wear is good, and ageing resistace is good, general serviceability temperature-20 ℃-80 ℃, v＜50m/s, P＜300kw, i＜10 are for requiring synchronous transmission also to can be used for the low speed transmission.
Description of drawings
Fig. 1 is the schematic diagram of the hardware syndeton of a kind of permagnetic synchronous motor of the present invention.
Number in the figure explanation: 1. permagnetic synchronous motor, 2. connecting axle, 3. gear.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Consult Fig. 1, the hardware syndeton of a kind of permagnetic synchronous motor of the present invention comprises the permagnetic synchronous motor 1, connecting axle 2 and the gear 3 that connect successively.
Be connected with synchronous band on the gear 3, band is to be strength layer with the steel wire rope synchronously, outward coated with the endless belt of polyurethane or neoprene, and the dentation of interior Zhou Weiyu gear 3 engagements of being with synchronously.
During band transmission synchronously, gearratio is accurate, and the control precision height is little to the axle active force, compact conformation, oil resistant, resistance to wear is good, and ageing resistace is good, general serviceability temperature-20 ℃-80 ℃, v＜50m/s, P＜300kw, i＜10 are for requiring synchronous transmission also to can be used for the low speed transmission.
Above-described embodiment just is to allow the one of ordinary skilled in the art can understand content of the present invention and enforcement according to this for technical conceive of the present invention and characteristics being described, its objective is, can not limit protection scope of the present invention with this.Variation or the modification of every equivalence that the essence of content has been done according to the present invention all should be encompassed in protection scope of the present invention.
