Abstract
The utility model discloses an externally hung type motor revolutions counter, which comprises a count display mechanism, a revolutions input mechanism connected with the rotating shaft of a motor, and a speed-reducing transmission mechanism. The speed-reducing transmission mechanism is reduced in transmission ratio. One end of the speed-reducing transmission mechanism is connected with the revolutions input mechanism and the other end of the speed-reducing transmission mechanism is connected with the display input component of the count display mechanism. According to the technical scheme of the utility model, the externally hung type motor revolutions counter is simple in structure and low in manufacturing cost. Due to the adoption of the externally hung type motor revolutions counter, the actual service time of the drive device of each motor can be known more accurately. Therefore, the motor revolutions counter enables the development of operation schemes and maintenance plans to be more reasonable. Moreover, the maintenance cost is saved.
Description
Technical field
The utility model relates to the metering of motor rotating cycle and reads, and is specifically related to a kind of external hanging type motor revolution counter.
Background technology
When calculator room equipment operation and maintenance, often only according to each motor, determine whether to switch running time or noly need maintenance.The application of converter technique makes the fully loaded work duration of the reality of motor be shorter than its running time.If weigh judgement according to the real work rotating cycle of motor, can grasp more accurately it and move actual duration, extend maintenance period before, cost-saving.
summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of simple in structure, low cost of manufacture and can grasp accurately each motor driving apparatus motor revolution counter of service time.
In order to solve the problems of the technologies described above the technical solution of the utility model, be: external hanging type motor revolution counter, comprise the revolution input mechanism of counting indication mechanism, being connected in machine shaft, and one end is connected in revolution input mechanism and has the reduction gearing mechanism of the gearratio dwindling, the other end of reduction gearing mechanism is connected in the demonstration input block of counting indication mechanism.
As a kind of preferred mode, revolution input mechanism comprise be connected in machine shaft the first permanent magnet, be connected in the second permanent magnet of reduction gearing mechanism and be connected in the revolution power shaft of the second permanent magnet; The first permanent magnet is relative with the second permanent magnet heteropole.
As a kind of preferred mode, reduction gearing mechanism comprises the first worm screw, second driving shaft, the 3rd power transmission shaft that is connected in described revolution power shaft; One end of second driving shaft is provided with second turbine meshing with the first worm screw, and the other end is provided with the second worm screw; One end of the 3rd power transmission shaft is provided with three turbine meshing with the second worm screw, and the other end is provided with the 3rd worm screw.
Show that input block is preferably gear or the turbine meshing with described the 3rd worm screw.
External hanging type motor revolution counter of the present utility model is simple in structure, low cost of manufacture, and pure mechanical realization, is not subject to power limitations, and because be magnetic transmission, seal without spin, and dustproof and waterproof grade is high, can be used for various severe building environments, strong adaptability.Can grasp more accurately the true service time of each motor driving apparatus, thereby formulate more rational operation scheme and repair and maintenance plan, save maintenance cost.

Embodiment
Execution mode of the present utility model is as shown in Figure 1 known, external hanging type motor revolution counter, comprise the revolution input mechanism of counting indication mechanism 1, being connected in machine shaft 2, and one end is connected in revolution input mechanism and has the reduction gearing mechanism of the gearratio dwindling, the other end of reduction gearing mechanism is connected in the demonstration input block 6 of counting indication mechanism 1.
Revolution input mechanism comprise be connected in machine shaft 2 the first permanent magnet 3, be connected in the second permanent magnet 4 of reduction gearing mechanism and be connected in the revolution power shaft 5 of the second permanent magnet 4; The first permanent magnet 3 is relative with the second permanent magnet 4 heteropoles.The first permanent magnet 3 carries out transmission with the second permanent magnet 4 permanent magnets by relative attracting each other of magnetic pole, by the first permanent magnet 3 being arranged on machine shaft 2, drive the first permanent magnet 4 across plastics clamshell 14 to rotate, drive revolution power shaft 5 to rotate thereupon.
Reduction gearing mechanism comprises the first worm screw 7, second driving shaft 8, the 3rd power transmission shaft 11 that is connected in revolution power shaft 5; One end of second driving shaft 8 is provided with second turbine 9 meshing with the first worm screw 7, and the other end is provided with the second worm screw 10; One end of the 3rd power transmission shaft 11 is provided with three turbine 12 meshing with the second worm screw 10, and the other end is provided with the 3rd worm screw 13.
Show that input block 6 is gear or the turbine meshing with described the 3rd worm screw 13.
After installing, the utility model in the running, by reduction gearing mechanism, realizes the gearratio of 1500:1.Revolution power shaft drives the first worm screw 7 to rotate, and the first worm screw 7 drives the second turbine 9 to rotate, and the gearratio between the first worm screw 7 and the second turbine 9 is 10:1; The second turbine 9 is transmitted to the second worm screw 10, the second worm screws 10 by the rotation after reducing by gearratio by second driving shaft 8 and drives the 3rd turbine 12 to rotate, and the gearratio between the second worm screw 10 and the 3rd turbine 12 is 10:1; The 3rd turbine 12 is transmitted to the 3rd worm screw 13 by the rotation after reducing by gearratio by the 3rd power transmission shaft 11; The 3rd worm screw 13 drives the gear or the turbine that show input block 6 to rotate, and gearratio is 15:1.Show that the gear of input block 6 or the counting indication mechanism 1 that turbine is a minute with precision are connected.First designation number of the every rotation 1500 circle counting indication mechanisms 1 of motor is rotated lattice, first indicating device second designation number that turn around turns lattice, namely complete one circle sixth, second designation number often turns around the 3rd and turns lattice, by that analogy a designation number to the last.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection range of claims of the present invention.
