Abstract
The utility model discloses a permanent magnetic braking clutch. The permanent magnetic braking clutch comprises a main shaft (1), a braking clutch disc (2), a magnetizable magnet (3), a coil (4), a permanent magnet (5), a mounting bracket (6), a left magnetic yoke (7) and a right magnetic yoke (8), wherein the braking clutch disc (2) is arranged on the main shaft (1); the magnetizable magnet (3) is arranged on the inner side of the coil (4); the permanent magnet (5) is arranged between the coil (4) and the mounting bracket (6); the left magnetic yoke (7) and the right magnetic yoke (8) are arranged on both sides of the magnetizable magnet (3), the coil (4) and the permanent magnet (5) respectively. The magnetizable magnet (3) is placed into the coil (4), and anode and cathode momentary high-voltage current passes through the two ends of the coil (4) to change the magnetic loop of the permanent magnet. Braking and separation are realized. The permanent magnetic braking clutch has the characteristics of simple structure, quick braking and releasing, low processing cost, convenience in maintenance, long service life, low material consumption, long service life and the like.
Description
Technical field
The utility model relates to electromagnetic braking clutch field, relates in particular to a kind of novel permanent magnet braking clutch.
Background technique
Produce at present and the electromagnetic braking clutch of application is the theory and structure of mechanical friction braking, discharge friction disk after adopting power-off, utilize the thrust of spring to make frictional force braking after the movement of friction disk; Energising produces electromagnetic force and inhales full friction disk, makes to produce behind gap between friction disk and wearing piece work running.Utilize frictional force braking to want certain limitation, easily produce braking failure.Friction plate used after certain life-span, essential replacing.The friction catch face contacting with friction plate is essential clean without many requirements such as greasy dirts.Owing to adopting the principle of mechanical friction braking, the shortcoming such as the time of braking and clutch is long, and braking moment is little, and component are many, and production and processing cost is high, and labor intensity is large.
Summary of the invention
The purpose of this utility model provide solving above-mentioned deficiency of the prior art a kind of simple in structure, period of braking is short, it is simple to manufacture, easy to maintenance, long service life, large, the practical novel permanent magnet braking clutch of braking moment.
As shown in Figure 1: a kind of novel permanent magnet braking clutch, comprise main shaft 1, braking clutch disc 2, can charged magnet 3, coil 4, permanent magnet 5, mounting bracket 6, and left yoke 7 as shown in Figure 2, right yoke 8.
It is characterized in that: as shown in Figure 1, braking clutch disc 2 is located on main shaft 1, can charged magnet 3 be located at coil 4 inner sides, permanent magnet 5 is located between coil 4 and mounting bracket 6.
It is characterized in that: as shown in Figure 2, left yoke 7 and right yoke 8 are located at respectively can charged magnet 3, coil 4, permanent magnet 5 both sides.
The utility model adopts can charged magnet 3 in the interior placement of coil 4, logical to coil 4 two ends by both positive and negative polarity instant high-voltage electric current to change the magnetic loop of permanent magnet.Realize braking and separate.Therefore the utlity model has simple in structure, braking with discharge the features such as fast, processing cost is low, easy to maintenance, long service life, braking and release is fast, few with material, long service life.
Brief description of the drawings
Accompanying drawing 1 structural representation of the present utility model.
Accompanying drawing 2 magnetic loop structural representation of the present utility model.
Embodiment
Mode of execution of the present utility model is now described in detail in detail by reference to the accompanying drawings.
As shown in Figure 1: a kind of novel permanent magnet braking clutch, comprise main shaft 1, braking clutch disc 2, can charged magnet 3, coil 4, permanent magnet 5, mounting bracket 6, and left yoke 7 as shown in Figure 2, right yoke 8.
It is characterized in that: as shown in Figure 1, braking clutch disc 2 is located on main shaft 1, can charged magnet 3 be located at coil 4 inner sides, permanent magnet 5 is located between coil 4 and mounting bracket 6.
As shown in Figure 2: left yoke 7 and right yoke 8 are located at respectively can charged magnet 3, coil 4, permanent magnet 5 both sides.
As shown in Figure 2: in the time that coil 4 passes through instant high-voltage and electric current, can charged magnet 3 be magnetized, now the magnetic line of force of permanent magnet 5 by path is: left yoke 7-permanent magnet 5-right yoke 8-braking clutch disc 2-left yoke 7, forms a magnetic loop.After now braking clutch disc 2 is attracted, produces and move, braking clutch disc 2 can not rotate with main shaft 1, realizes braking function; In the time that coil 4 passes through reverse instant high-voltage and electric current, can charged magnet 3 by degaussing, now the magnetic line of force of permanent magnet 5 by path is: left yoke 7-permanent magnet 5-right yoke 8-and can charged magnet 3-left yoke 7, form a magnetic loop, now braking clutch disc 2 does not have suction, natural separation in the time that main shaft 1 rotates, realizes separation function.
It is simple in structure that the utility model provides one to have, braking with discharge fast, processing cost is low, easy to maintenance, long service life, braking and release is fast,, long service life few with material.
