Abstract
Disclosed is a low-play type motor, comprising a brush holder assembly (4), a rotor assembly (1), a stator assembly (2), an active gear assembly (20), and a decelerator assembly (21), wherein the rotor assembly is composed of a rotor shaft (24), a rotor (25), and a commutator (26); the front end of rotor shaft of the rotor assembly is of a double-headed worm structure; the rotor shaft is provided with a rotor spring (6) thereon at a position close to the brush holder assembly; and the carbon brush holder (27) of the brush holder assembly is provided with an over-current heat protector connected with the carbon brush (28) of the carbon brush holder. WWhen the low-play type motor is in high-speed rotation, no large play or axial play will occur, thereby reducing motor noise. Moreover, the motor ablation resulting from motor over-current or over heating can also be effectively prevented, thereby improving the working performance and prolonging the service lifetime of the motor. The low-play type motor can be used as a wiper motor for high-end cars or employed as a garage door motor, or as a sliding door motor.
Description
Technical field
The utility model relates to a kind of motor.
Technical background
At present, existing common (DC) motor generally is made of brush handle assembly, rotor assembly, stator module, driving gear assembly, decelerator assembly etc., wherein, rotor assembly comprises armature spindle, rotor, commutator, the front end of armature spindle is a single start worm formula structure, its weak point is: bigger play can take place in armature spindle when motor runs up, and it is also higher to produce noise.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of low play formula motor that can effectively reduce armature spindle play and noise is provided.
The purpose of this utility model realizes by following technical solution: a kind of low play formula motor, comprise brush handle assembly, rotor assembly, stator module, driving gear assembly, decelerator assembly, wherein rotor assembly is made up of armature spindle, rotor and commutator, the front end of the armature spindle of described rotor assembly is a double-thread worm formula structure, and on this armature spindle, and the rotor spring is housed near the brush handle assembly place.The overcurrent thermal protector that links with carbon brush is housed on the carbon brush holder of described brush handle assembly.
After adopting the utility model structure, the armature spindle of tool double-thread worm formula and on the effect of rotor spring under, when motor runs up, do not have big play and axial endplay, thus the also corresponding motor noise that reduced.And, can effectively prevent over current of motor or the overheated motor ablation that causes, the service behaviour and the life-span of having improved motor because the overcurrent thermal protector has been installed.
Description of drawings
Fig. 1 is the structural representation of the low play formula motor of the utility model.
Fig. 2 is the A-A view of Fig. 1.
The structural representation that Fig. 3 links for brush handle assembly among Fig. 1 and overcurrent thermal protector.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model hangs down play formula motor, comprise brush handle assembly 4, rotor assembly 1, stator module 2, cover plate assembly 18, driving gear assembly 20, decelerator assembly 21, wherein rotor assembly 1 is made up of armature spindle 24, rotor 25 and commutator 26, the front end of the armature spindle 24 of described rotor assembly 1 is a double-thread worm formula structure, and on this armature spindle 24, and locate to be equipped with rotor spring 6 near brush handle assembly 4 (and commutator 26).
As shown in Figure 3, brush handle assembly 4 comprises carbon brush holder 27, carbon brush 28; In order effectively to prevent over current of motor or the overheated motor ablation that causes, the overcurrent thermal protector 29 that links with its carbon brush 28 is housed on the carbon brush holder 27 of described brush handle assembly 4.Linking of commutator (indirectly) in this overcurrent thermal protector and the motor, carbon brush (directly) is series relationship.When overcurrent or superheating phenomenon appearred in motor, this overcurrent thermal protector can be controlled motor shut down it.
This product is mainly used in medium-to-high grade car wiper motor, also can be applicable to motor for door of garage, translation door motor etc.
Claims (2)
1. one kind low play formula motor, comprise brush handle assembly (4), rotor assembly (1), stator module (2), driving gear assembly (20), decelerator assembly (21), wherein rotor assembly (1) is made up of armature spindle (24), rotor (25) and commutator (26), it is characterized in that: the front end of the armature spindle (24) of described rotor assembly (1) is a double-thread worm formula structure, and locates to be equipped with rotor spring (6) at last, the also close brush handle assembly (4) of this armature spindle (24).
2. low play formula motor as claimed in claim 1 is characterized in that: the overcurrent thermal protector (29) that links with its carbon brush (28) is housed on the carbon brush holder (27) of described brush handle assembly (4).
