Description
Technical field
The present invention relates to a kind of adjustable linear motor of air gap.
Background technology
Air gap refers to existing space air gap between motor stator and rotor, and the size of air gap value can influence electric motor starting torsion
The efficiency of cutting magnetic induction line when square and operation.Air gap is excessive, and motor power factor will be caused to decline；Air gap is too small to make motor ventilation
Hydraulic performance decline, so as to influence the heat dissipation of motor, aggravates motor temperature rise.However, at present between the rotor of traditional line motor
Air gap be fixed nonadjustable.
The content of the invention
1st, technical problem to be solved：
Space air gap between the motor stator and rotor of existing linear motor is non-adjustable.
2nd, technical solution：
In order to solve problem above, the present invention provides a kind of adjustable linear motor of air gap, including bottom plate 1, backboard 4, stator
10 are arranged among the bottom plate 1, and guide rail 2 is arranged on 1 both ends of bottom plate, and sliding block 9 is provided with the guide rail 2, and backboard 4 is fixed on
On sliding block 9, mover 5 and connecting rod 6 connect, and the connecting rod 6 passes through the backboard 4, the connecting rod positioned at backboard more than 4
6 are equipped with sunk key, and the sunk key and the gear 7 on backboard 4 are adapted.
The sunk key is located at the top of connecting rod 6.
The gear 7 is arranged on 4 upper surface of backboard by gear stand 8.
The backboard 4 is equipped with circular hole, and the connecting rod 6 passes through backboard 4 by circular hole.
The circular-hole internal-wall is smooth, and the Circularhole diameter is slightly larger than 6 basal diameter of connecting rod.
3rd, beneficial effect：
The adjustable linear motor of air gap provided by the invention, is adjusted between stator and rotor in real time by air gap adjusting mechanism
Size of gaps, so as to improve motor performance；It is simple in structure, easily implement；It is low to manufacture cost, can be with large-scale promotion.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
Below by attached drawing, the present invention is described in detail.
To be set as shown in Figure 1, the present invention provides a kind of adjustable linear motor of air gap, including bottom plate 1, backboard 4, stator 10
Put among the bottom plate 1, guide rail 2 is arranged on 1 both ends of bottom plate, and sliding block 9 is provided with the guide rail 2, and backboard 4 is fixed on sliding block
On 9, mover 5 and connecting rod 6 connect, and the connecting rod 6 passes through the backboard 4, the connecting rod 6 positioned at backboard more than 4
Equipped with sunk key, the sunk key and the gear 7 on backboard 4 are adapted.
The purpose of the invention is to can occasionally adjust the air gap 3 between the stator 10 and mover 5.
Stator 10 is arranged on bottom plate 1, fixed, mainly adjusts mover 5 and stator by moving up and down for mover 5
The distance between 10.
Technical solution used is that mover 5 and connecting rod 6 connect, and the connecting rod 6 passes through backboard 4, there is provided one kind even
The structure that extension bar 6 can be moved up and down occasionally, by moving up and down for connecting rod 6, so that moving up and down for mover 5 is driven, so that band
Dynamic mover 5 moves up and down.
The present invention is by the setting gear 7 on backboard 4, and the upper surface setting that connecting rod 6 is located at backboard is mutually fitted with gear
The sunk key matched somebody with somebody, moves up and down connecting rod 6 by the cooperation of gear 7 and sunk key.Since the sunk key is located at connecting rod 6
Top, in order to which gear and sunk key are preferably adapted to, sets a gear stand 8, shown gear 7 by gear stand 8 by setting
In 4 upper surface of backboard.The distance of the sunk key bottom and backboard is just the maximum downward displacement of connecting rod 6, the center of gear 7
The distance between backboard is the maximum upward displacement of connecting rod 6.Adjust position and gear of the scope of air gap 3 by sunk key
Highly determine.
In order to which connecting rod 6 preferably moves up and down, circular hole is set, and the circular-hole internal-wall is smooth, Er Qiesuo on the backboard 4
It is more bigger than the diameter of 6 bottom surface of connecting rod to state the diameter of circular hole, makes connecting rod 6 and can be moved up and down along circular hole.
The course of work of the adjustable linear motor of air gap is as follows, rotate gear 7, due on gear 7 and connecting rod 6
Sunk key is adapted, and when gear 7 rotates clockwise, connecting rod 6 moves down, and when gear 7 rotates counterclockwise, connecting rod 6 is to moving up
It is dynamic.
Embodiment more than original text is merely illustrative of the invention's technical idea, it is impossible to the protection model of the present invention is limited with this
Enclose, every according to technological thought proposed by the present invention, any change done on the basis of technical solution, each falls within guarantor of the present invention
Within the scope of shield.The technology that the present invention is not directed to can be realized by existing technology.
