Abstract
The utility model discloses a permanent magnet deceleration type direct current motor, belongs to an automobile starter motor, and aims at providing a starter motor which is small in volume and simple in structure. The permanent magnet deceleration type direct current motor comprises a motor, a deceleration mechanism, an electromagnet, a switch and a clutch. The motor is composed of a stator (10), a carbon brush (12) and an armature (11). The deceleration mechanism is composed of a spiral shaft (16) supported in a casing (9), planetary gears (13) which are connected with the spiral shaft through a wheel carrier (14), and a sun gear (4) which is engaged with the planetary gear. The electromagnet consists of a coil (1) and a spring (15) which are fixed in the casing (9) and a moving iron core (3) which is disposed in the coil. The switch is composed of a switching casing (7) which is fixed onto the casing (9), a fixed contact (6) and a pull bar (5) which are disposed in the switch casing and a moving contact (8) which is disposed on the pull bar. The clutch is composed of a left clutch block (17) and a slide block (2) which are disposed on the spiral shaft (16).
Description
Technical field
The utility model relates to a kind of direct current machine, relates in particular to a kind of permanent magnetism slowdown type direct current machine, belongs to automobile starting motor.
Background technology:As everyone knows, automobile starting motor is made of motor, reducing gear, electromagnet, switch and clutch usually.Because the reducing gear of orthodox car actuating motor adopts common gear reduction and common clutch, so volume is bigger, can not satisfy the requirement of the narrow and small installing space of Hyundai Motor.
Summary of the invention:At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of volume permanent magnetism slowdown type direct current machine little, in light weight, simple in structure.
To achieve these goals, the utility model by the following technical solutions: it comprises motor, reducing gear, electromagnet, switch and clutch; Described motor is by the stator and the carbon brush that are fixed in the casing, the armature that is bearing in this casing constitutes, described reducing gear is by the helical axis that is bearing in the casing, the wheel carrier of fixedlying connected with this helical axis, being located at four planetary gears that mesh with the armature shaft central gear on this wheel carrier constitutes, described electromagnet is by the coil that is fixed in the casing, be located in this coil and pull bar) the moving iron core that is connected, be located at and move the spring formation that iron core holds out against in the casing, described switch is by the switch housing that is fixed on the casing, be fixed on the fixed touching plate in this switch housing, be located at the pull bar in this switch housing, the movable contact spring that is located on this pull bar constitutes, and described clutch is made of the left clutch block and the slide block that are located on the helical axis.
Compared with the prior art, the utility model utilizes planetary gear speed reducing mechanism to substitute traditional gear reduction unit owing to adopted technique scheme, and utilizes moving iron core to replace shift fork; Therefore can realize that reducing gear and relay are concentric with motor shaft, reduce the volume and weight of complete machine effectively, structure is also simple more compact; Can satisfy the requirement of the narrow and small installing space of Hyundai Motor fully.
