Description
Technical field
The present invention relates to a kind of driving device for oil field equipment.Particularly one kind disclosure satisfy that low speed, big torque, speed
Spend the deceleration permanent magnet type synchronous motor of adjustable requirement.It is particularly suitable for the driving of beam-pumping unit.
Background technology
In recent years, as permasyn morot rapidly promotes and applies, because its structure is relatively simple, operation is improved
Reliability, efficiency and power density, therefore be to apply a kind of more and more extensive driving device in every field in recent years.
Traditional beam pumping unit driving device is made of prime mover, belt, gear-box three parts.Prime mover is usually
Induction conductivity, its high speed low torque drive gear reducer by V belt translation, and low speed high torque is exported by gear reducer reduction of speed.It is this
Induction conductivity efficiency at light load and power factor are very low, and starting torque is little, it is difficult to meet the needs that bringing onto load starts.When
Often occurring the load of overload in short-term for driving, starting current is very big, adds the capacity of required supply transformer, so that
Increase great amount of investment.The starting torque of conventional motors is small, tends not to the needs for meeting full load starting, so that there is still a need for increase
Hold and form " low load with strong power ", the problems such as conventional motors are also low there are reliability, high failure rate, big energy-consuming, noise is big.Skin
V belt translation will play pendulum in overload, and efficiency drastically declines, abrasion aggravation, seriously affect the service life of belt, belt
Replacement frequency is high.With the increase of the degree of wear, hysteresis loss makes belt to produce in operation to stretch repeatedly, particularly belt wheel
On make to produce friction inside belt body around the joint performance of quyi and cause power loss.
To solve the above-mentioned problems, Patent publication No is the " a kind of to pump without belt-type walking beam of 105156075 A of CN
Machine ", the structure of record：Including base, stent, connecting rod, pitman shaft, crank, output shaft, gearbox, motor.It is to tradition
Beam-pumping unit drive part improved without belt, and motor output shaft and reducer input shaft are connected by shaft coupling
Connect, retarder slows down using three-level rectangular axis retarder, although saving V belt translation link, improves efficiency of the pumping unit, subtracts
Few maintenance cost, but motor and retarder are attached by shaft coupling, shaft coupling centering precision prescribed is high, to assembler
Make raising difficulty, in the presence of having relative displacement if there is two axis, two axis additional loads will be caused, while can also cause and shake
It is dynamic, operation unbalance loading is caused, influences the service life of retarder and motor.Slow down not only to reduce using three-level rectangular axis retarder and pass
Efficiency of movement, increases overall dimensions, while can also increase cost, is installed in terms of braking using brake on high speed gear shaft,
Powerful braking moment can make gear carrying excess load cause to damage, and increase brake fade risk.
The content of the invention
The object of the present invention is to provide a kind of deceleration permanent magnet type synchronous motor, solves traditional drives connection structure
Concentricity it is bad, installation difficulty is larger, and operation unbalance loading influences service life, and transmission efficiency is low, the problems such as easily making brake fade,
It is reasonable that it is designed, compact-sized, improves transmission efficiency, increases the reliability of braking, stable, prolongs the service life, and reduces
Overall dimensions, save cost, it is easy to disassemble, achieve the purpose that installation, it is easy to maintain.
The technical solution adopted in the present invention：The deceleration permanent magnet type synchronous motor includes the reduction-gear housing with substrate
Body, the reduction gearing mechanism fitted together with reduction case, permasyn morot and brake apparatus, technical points
It is：The reduction gearing mechanism is by the high speed input shaft for being fixed with high gear and the low-speed output shaft structure for being fixed with low-speed gear
Into the rotor assembly of permasyn morot is assembled in stretching reduction case one end of high speed input shaft, by stator line bag pressure
Stator module mounted in stator casing composition is fixed on reduction-gear housing body sidewall, and it is defeated that the brake drum of brake apparatus is assembled in low speed
Stretching reduction case one end for being provided with Auxiliary support of shaft, the Auxiliary support being fixed on substrate be provided with bearing and
Left and right supports end cap, freely-supported is formed by the bearing and left and right supports end cap of Auxiliary support by the brake drum end of low-speed output shaft
Girder construction, the braking arm component of brake apparatus is by bracket assembled on the substrate of reduction case；It is defeated that startup is assembled in high speed
The rotor assembly for entering axis drives coaxial high gear to rotate, and the low-speed gear for making to be meshed with high gear drives low speed output
Axis rotates, and after triggering braking, the rapid braking of brake arm for braking arm component is assembled on the brake drum of low-speed output shaft.
The high speed input shaft is assembled on reduction case by left and right input end cap.
The low-speed output shaft is fixed with one end of low-speed gear, and reduction case is assembled in by left and right output end cap
On, one end for being assembled with brake drum that low-speed output shaft stretches out reduction case is provided with Auxiliary support.
The shaft end that the high speed input shaft is assembled with rotor assembly is provided with resolving encoder.
The present invention has the advantage that and good effect is：Since the reduction gearing mechanism of the present invention is by being fixed with high gear
High speed input shaft and be fixed with low-speed gear low-speed output shaft form single-stage speed reducing, using a pair be meshed it is high and low
Fast gear is effectively combined permasyn morot with retarder, with permasyn motor direct driving retarder, so its
Design is reasonable, compact-sized, improves transmission efficiency, increases the reliability of braking, stable, prolongs the service life, and reduces whole
Body size, save cost, it is easy to disassemble, achieve the purpose that installation, it is easy to maintain.It is exactly specifically：Because high using retarder
Fast input shaft stretches out the rotor assembly of the cantilever end assembling permasyn morot of reduction case, realizes permasyn morot
Output shaft coaxial with retarder high speed input shaft stroke driving rotor assembly, this addresses the problem traditional decelerator need by
Motor output shaft is rigidly connected with retarder high speed input shaft by shaft coupling or sleeve, and existing concentricity is bad and transports
The problems such as row unbalance loading.Compared to traditional decelerator, transmission efficiency is improved, saves cost.It is fixed that stator line bag is fitted in
The stator module formed in subshell is assembled on reduction-gear housing body sidewall with the mode of flanged joint, can so make permanent-magnet synchronous
Electric motor structure is compacter, stable.Retarder uses gear single-stage speed reducing, the volume of retarder is more added and subtracted
It is small, beneficial to output low speed high torque.Brake drum end is assembled with retarder low-speed output shaft, by being fixed on reduction case
Substrate on the simple beam structure that forms of Auxiliary support, can not only improve volume utilization, reduce overall dimensions, Er Qiezeng
Add dynamic reliability.Therefore, the present invention solve traditional drives connection structure concentricity it is bad, installation difficulty compared with
Greatly, running unbalance loading influences service life, and transmission efficiency is low, the problems such as easily making brake fade.
