Abstract
The utility model discloses a novel worm and gear DC motor, which is characterized in that a motor cabinet (1), a cabinet housing assembly connected to the motor cabinet (1), a worm gear positioned within the motor cabinet (1), and an armature assembly positioned within the cabinet housing and connected to the worm gear assembly. The worm and gear DC motor totally changes a traditional concept that worm gear cabinet, a stator framework and an end cap are designed independently and integrates the worm gear cabinet, the stator framework and the end cap, so that the assembling procedure and processing procedure for assembling the three parts are effectively eliminated.
Description
Technical field
The utility model relates to a kind of direct current machine, specifically refers to a kind of new type worm wheel worm screw DC motor.
Background technology
DC motor is the motor that current people often will use, and it has been applied in daily life widely.The structure of traditional DC motor, by the worm gear case engaging for worm and gear, is arranged on the magnetic shoe of casing inside, the electric motor end cap being connected with casing, and be arranged on casing inside rotor assembly form.Although the technology of DC motor is comparatively ripe, the structural design of traditional DC motor, manufacturing process is more, not only high to each parts matching requirements precision, but also need to carry out fine finishining to part, and therefore its production efficiency is low, and cost is higher.
Utility model content
The purpose of this utility model is to optimize the existing structural design of traditional low powered DC motor, avoid production process more, the defect that structure is comparatively complicated, provides a kind of reasonable in design, and can effectively save operation, new type worm wheel worm screw DC motor very is easily installed.
The purpose of this utility model is achieved through the following technical solutions: a kind of new type worm wheel worm screw DC motor, mainly by motor case, the case component being connected with this motor case, be arranged on the Worm-gear assembly of motor case inside, and be arranged on the armature assembly formation that case component is inner and be connected with Worm-gear assembly.
Further, described case component, by the outer cage being fixedly linked with worm gear cabinet, is arranged on the inner casing of outer cage inside, and magnetic shoe composition in inner casing.
Described armature assembly is made up of the armature with worm screw.
In order to realize preferably the utility model, described Worm-gear assembly is by worm gear, be arranged on the oiliness bearing of worm gear cabinet inside, be arranged on worm gear cabinet end and for carrying the ball bearing of worm screw end of armature, and for sealing the worm gear lid composition of whole worm gear cabinet; The screw rod of described worm gear matches with oiliness bearing, and whole worm gear can be at worm gear cabinet internal rotating, and the worm screw of described armature is meshed with this worm gear.
The utility model is compared and is had the following advantages and beneficial effect compared with prior art:
(1) the utility model has thoroughly changed traditional worm gear case, stator skeleton and the end cap separately theory of design of a part of respectively doing for oneself, initiative be integrated worm gear case, stator skeleton and end cover designs, thereby effectively removed the assembly process of these three component combinations together time and the finishing step of parts from.
(2) the utility model is Promethean is fixed on the worm screw of armature in worm gear cabinet by two bearings, therefore can greatly reduce and need supporting assembly, and its runnability is very reliable.
(3) the utility model is directly shelved on magnetic shoe in the posting of motor case, and by interior outer cage, magnetic shoe is compressed to location, therefore avoids traditional handicraft magnetic shoe need to stick on the operation and the defect that has this generation on casing.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Reference numeral title in above accompanying drawing is respectively:
1-motor case, 2-outer cage, 3-inner casing, 4-magnetic shoe, 5-armature, 6-brush holder, 7-rolling bearing, the left rubber sleeve of 8-, the right rubber sleeve of 9-, 10-worm gear, 11-oiliness bearing, 12-ball bearing, 13-worm gear lid.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, worm and gear DC motor of the present utility model mainly comprises motor case 1, case component, Worm-gear assembly and four large parts of armature assembly.Wherein, motor case 1 is for integrating the overall structure of worm gear case, stator skeleton and end cap, and this structure has effectively overcome the defect that traditional direct current machine also needs to make separately worm gear case, stator and end cap in the preparation.
Armature assembly is arranged on case component inside, and described case component, by the outer cage 2 being fixedly linked with motor case 1, is arranged on the inner casing 3 of outer cage 2 inside, and forms with the fixing magnetic shoe 4 of inner casing 3.When assembling, after armature is packed into being fixed on motor case, magnetic shoe is shelved in the magnetic shoe posting of motor case, packs inner casing 3 into, magnetic shoe is fixed, inner casing 3 relies on the locating ring location on motor case; Reinstall outer cage 2, located by the locating ring on motor case.
As shown in the figure, armature assembly comprises the armature 5 with worm screw, and brush holder 6, and left rubber sleeve 8 and right rubber sleeve 9, and brush holder 6 tightly blocks by left rubber sleeve 8 and right rubber sleeve 9 directly insert in the location notch of motor case body 1 fixing; When armature assembling, need first brush mount component to be packed into the position of commutator in worm screw, then ball bearing 7 is pressed in worm screw, pack ball bearing into worm screw end, then pack armature assembly into motor case, be fixed in motor case by ball bearing 7 and ball bearing 12.
Described Worm-gear assembly, by worm gear 10, is arranged on the oiliness bearing 11 of motor case 1 inside, is arranged on motor case 1 end and for carrying the ball bearing 12 of worm screw end of armature 5, and worm gear lid 13 forms.When installation, the output shaft of worm gear 10 is through oiliness bearing 11.Owing to will driving this worm gear 10 to rotate after armature 5 rotations, therefore this worm gear 10 will be meshed with the worm screw of armature 5.After worm gear 10 and worm screw are meshed, then worm gear lid 13 is built, by screw, it is fastened on motor case 1, to guarantee its protection effect.
As mentioned above, just can well realize the utility model.
