Abstract
The utility model relates to an electric machine with braking device, which comprises a front end cover, a bearing, a rotor, a rotor shaft, a stator, a back end cover and a braking device. The braking device comprises a spring, a dental clutch composed of a movable chain wheel and a fixed chain wheel, a friction plate and a brake disk, wherein, the spring is arranged between the movable chain wheel and the fixed chain wheel, and the brake disk are fixed with the movable chain wheel; the friction plate are arranged fixedly on the position of the back end cover corresponding to the brake disk, which is characterized in that the fixed chain wheel of the clutch is arranged fixedly on the rotator axis. By installing the fixed chain wheel of the clutch, the utility model solves the problems in the original technique that the texture of material of the fixed chain wheel is limited, which is with high requirement to the die casting technique, at the same time, the utility model ensures that the product quality of the electromotor will not be affected.
Description
One, technical field
The utility model belongs to electric motors, relates to a kind of motor that has brake gear.
Two, background technology
In the existing motor that built-in electromagnetic brake device is housed, its brake gear is generally by the jaw clutch of the end of a side iron core end ring that is located at armature spindle, the brake disc that is solidly installed with the movable chain wheel of above-mentioned clutch, be contained in forming on the electric motor end cap with the corresponding locational friction plate of brake disc, because the fixedly chain wheel of this clutch installs or is die cast as one with the iron core end ring, so just certainly will be to the intensity of the material of iron core end ring, there is higher requirement aspect such as hardness and anti-wear performance, cause the requirement of extrusion process to improve, directly influence the quality and the production efficiency of product; In addition, when fixedly chain wheel and iron core end ring install or are die cast as one, because material inhomogeneous and the imbalance of installing easily produce vibrations, thereby influence the quality of product during the motor operation.
Three, summary of the invention
The purpose of this utility model is to overcome weak point of the prior art and provides a kind of fixedly chain wheel material of clutch that makes unrestricted, to the motor of the less strap brake device of motor influence on system operation.
The utility model is realized as follows: a kind of motor of strap brake device, comprise front end housing (1), bearing (2), rotor (3), armature spindle (4), stator (5), rear end cap (6) and brake gear, this brake gear comprises by spring (7), the movable chain wheel (8) and the fixing jaw clutch of chain wheel (10) composition, friction plate (9), brake disc (11), its medi-spring (7) is contained in movable chain wheel (8) and fixedly between the chain wheel (10), brake disc (11) installs with movable chain wheel (8), friction plate (9) be packed on the rear end cap (6) with the corresponding position of brake disc (11) on, its main points are that the fixedly chain wheel (10) of described jaw clutch is packed on the armature spindle (4).
Because the fixedly chain wheel (10) of clutch is packed on the armature spindle (4), promptly fixedly chain wheel (10) is to separate die casting, partial installation with the iron core end ring, end ring can use normal flowability, the reasonable material of conductivity, and fixedly chain wheel can adopt the more outstanding material of intensity, hardness, so the material of the fixedly chain wheel of clutch is not subjected to the restriction of end ring material; Though installed brake gear in the motor additional, the influence that is subjected to during the motor operation is minimum, can not only make the stable and reliable for performance of brake gear, and guarantee the product quality of motor.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.Among the figure: 1 expression front end housing; 2 expression bearings; 3 expression rotors; 4 expression armature spindles; 5 expression stators; 6 expression rear end caps; 7 expression springs; 8 expression activity chain wheels; 9 expression friction plates; 10 expressions are chain wheel fixedly; 11 expression brake discs.
Five, embodiment
The utility model will be further described below with reference to drawings and Examples.
As shown in Figure 1, the motor that has brake gear comprises front end housing (1), bearing (2), rotor (3), armature spindle (4), stator (5), rear end cap (6), end in armature spindle (4) one sides, be provided with jaw clutch, wherein the fixedly chain wheel (10) of this clutch is packed on the armature spindle (4), movable chain wheel (8) is solidly installed with brake disc (11), movable chain wheel (8) with a spring (7) is fixedly arranged between the chain wheel (10), on rear end cap (6), on the position corresponding friction plate (9) is housed with brake disc (11).When electrical power, under electromagnetic action, the movable chain wheel (8) of jaw clutch is driven brake disc (11) and breaks away from friction plate (9) by adhesive, and motor has not had frictional resistance and operate as normal.When motor cut off the power supply, the movable chain wheel (8) in the jaw clutch lost the adhesive of electromagnetic force, and under the effect of spring (7), brake disc (11) is close to friction plate (9), and the frictional resistance that produces between the two can make motor stop operating at short notice.
Claims (1)
1. motor that has brake gear, comprise front end housing (1), bearing (2), rotor (3), armature spindle (4), stator (5), rear end cap (6) and brake gear, brake gear comprises by spring (7), the movable chain wheel (8) and the fixing jaw clutch of chain wheel (10) composition, friction plate (9), brake disc (11), its medi-spring (7) is contained in movable chain wheel (8) and fixedly between the chain wheel (10), brake disc (11) installs with movable chain wheel (8), friction plate (9) is packed on rear end cap (6) and the corresponding position of brake disc (11), it is characterized in that the fixedly chain wheel (10) of described jaw clutch is packed on the armature spindle (4).
