Abstract
The utility model discloses an armature rectifying device of a motor. The armature rectifying device comprises a rotary sleeve (9) with a slip ring (4). A first roller (5) supported by a support (8) is in rolling contact with the slip ring directly, and a rotor ring (14) is in contact with a second roller (1). The first roller (5) is coupled on the support (8), and a first spring (11) is further arranged on the lower portion of the support (8). The roller which is in contact with the rotor ring (14) is also supported by the support, and a second spring (2) is connected between a wiring terminal (6) and the support. According to the utility model, a structure design in which the rollers are supported by the springs so as to be in rolling contact with the slip ring and the rotor ring is adopted, so frictions therebetween are reduced, good mechanical performance and good electrical conductivity performance are ensured, no arc heating will be generated, the service life of the motor is greatly improved, the repair cycle is prolonged, and the device utilization rate is improved.
Description
Technical field
The utility model relates to a kind of AC and DC motor armature rectifying device.
Background technology
The armature rectifying device of common motor is the slip ring that has several intervals to be provided with, each slip ring all with a carbon brush frictional fit.Because intensity and the hardness of carbon brush are lower, carbon brush weares and teares very seriously in the process that motor runs up for a long time, directly influences its electric conductivity, and will often change.When carbon brush contacts with slip ring when bad, powerful electric arc also can burn many pits or salient point with the carbon brush surface, is easy to generate electric arc in the operation process again, forms vicious circle, has both influenced normal electric conductivity, causes security incident again easily.Usually the method that solves is by manual work sandpaper pad to be polished back and forth to seek them a contact-making surface preferably to be arranged between carbon brush and slip ring, guarantees that electric current normally passes through.But this is a kind of passive mode, if want workman's maintenance both to increase labour intensity, the more important thing is and wants stop production to overhaul, directly influences ordinary production.
Summary of the invention
The technical problem that the utility model will solve is the deficiency that exists in the prior art for overcoming, and a kind of AC and DC motor armature rectifying device with good contact performance and electric conductivity is provided.
The technical solution of the utility model is:
Roller by stent support directly contacts with the slip ring rolling; Rotor ring is also organized second roller with another and is contacted.
The further technological improvement of the utility model is:
Roller shaft is connected on the support, and the support bottom also is provided with first spring; The roller that contacts with rotor ring is connected with second spring also by stent support between binding post and the support.Press four slip ring fixed interval that three-phase four-wire system is provided with in the groove of rotary sleeve, and contact with four first rollers respectively.
Can find out from above technical scheme; Owing to taked spring support roller and slip ring and the rotor ring contacting structure of rolling to design, greatly reduced the friction between the two, and favorable mechanical contact performance and electric conductivity are arranged; Can not produce electrical arc erosion damages with heating; Thereby improved the useful life of motor to a great extent, also prolonged the time between overhauls(TBO) greatly simultaneously, and then improved utilization rate of equipment and installations even economic benefit.
Description of drawings
Fig. 1: the structural representation of the utility model.
The part-structure sketch map is looked on the right side of Fig. 2: Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2; A rotary sleeve 9 is fixed on the termination of motor shaft 10; Four slip rings 4 are set in the groove of rotary sleeve 9 outer rings at interval; The surface of each slip ring 4 is all supported by support 8 with one and roll in rotating first roller 5 surfaces contact, is provided with one first spring 11 and binding post 12 again below each support 8.Said slip ring 4 is to be processed by copper material; And roller 5 both can have been made by copper material, also can be by processing with the carbon brush identical materials.These four slip rings 4 and four first rollers 5 are that the three-phase four-wire system with alternating current is provided with.AC power is directly introduced and is conducted to slip ring 4 through first roller 5 from binding post 12 and drives rotor rotation.
In order to guarantee the concentricity of motor shaft 10 rotations, an interior cover 7 that has bearing can also be set between bearing 3 and motor shaft 10 again.Said rotary sleeve 9, slip ring 4, first roller 5 and support 8, first spring 11, binding post 12 all are housed in the shell 13, to play a protective role.
If as direct current machine, on rotor, be provided with a rotor ring 14 so, this rotor ring 14 contacts with other one group of second roller 1, and this second roller 1 also is provided with spring 2 also by stent support between support and the binding post 6.DC power supply is inserted by binding post 6, and through second roller 1 and rotor ring 14 conduction, thereby drive rotor rotation.
Owing to below each roller, all be provided with spring, and the elastic force of each spring can be guaranteeing the contact performance of roller and slip ring and rotor ring, so can guarantee their electric conductivity, in the rotor high-speed operation process, can not produce electric arc and generate heat.Also because roller and slip ring and rotor ring are rolling friction, it is very little to wear and tear, thereby improves greatly the useful life and the time between overhauls(TBO) of motor.
Claims (4)
1. motor armature rectifying device, it comprises a rotary sleeve (9) that has slip ring (4), it is characterized in that first roller (5) that is supported by support (8) directly contacts with slip ring (4) rolling; Rotor ring (14) also contacts with second roller (1).
2. the armature rectifying device of motor as claimed in claim 1 is characterized in that first roller (5) is coupling on support (8), and support (8) bottom also is provided with first spring (11); Second roller (1) that contacts with rotor ring (14) is connected with second spring (2) also by stent support between binding post (6) and the support.
3. the armature rectifying device of motor as claimed in claim 1, four slip rings (4) fixed interval that it is characterized in that being provided with by three-phase four-wire system and contact with four first rollers (5) respectively in the groove of rotary sleeve (9).
