Description
Technical field
DC injection braking motor of the present utility model with constant pressure carbon brush is by constant pressure carbon brush, motor stator, rotor and direct current
The direct current generator of brake composition, belongs to electromechanical integrated product, can be widely applied to automobile electricity capstan winch and oil pump and driving electricity
Machine.
Background technology
Battery power can be converted into mechanical energy by dc motor, different according to purposes, there is different operating voltages, work
Rotating speed and each model direct current generator of torque, size differ, and mounting means is different.What is had can change using mechanical carbon brush
To what is also had can be commutated with applying electronic, and usually, the high-power and direct current generator of the high current mechanical carbon brush of application more commutates.
The direct current generator to be commutated using mechanical carbon brush, the pressure of carbon brush typically use spring structure.But because carbon brush exists
There is larger abrasion in the course of work, so, carbon brush just needs to reserve wear extent, so as to, new motor carbon brush length, spring pressure
Power is big, and carbon brush abrasion is fast, and to the motor later stage, after carbon brush abrasion, spring pressure lengthens with stroke and reduces or lose spring force, electricity
Machine service behaviour declines.So many high-end motor manufacturers, spend big cost to go to study spring material and structure, keep bullet as far as possible
Spring force is constant, and this also just considerably increases motor cost.
On the other hand, there are many fields of employment, it is necessary to motor will be braked immediately after stopping, such as, automobile electricity capstan winch
With part motor etc., this just needs the direct current generator that can be just braked after power-off.
The content of the invention
In order to solve existing motor to brush holder spring structure and material high request, cost is reduced, meets power-off brake need
Ask, the DC injection braking motor provided by the utility model with constant pressure carbon brush is good using simple pressure texture, manufacturing process.
Technical scheme is used by the utility model solves its technical problem：DC injection braking motor bag with constant pressure carbon brush
Include motor rear cover, constant pressure carbon brush component, rotor assembly, stator module, restraining coil component, tripping spring, spring guide finger, system
Dynamic friction ring, drag ring sheath, keep plate, front motor cover, carbon brush holder, sleeve pipe, depression bar, extension spring and carbon brush, constant pressure carbon brush component
It is fixed in motor rear cover, under carbon brush holder support, depression bar can rotate around sleeve pipe, and extension spring can pull depression bar to push down carbon brush,
Pressure is produced to rotor assembly commutator, extension spring will become big to depression bar angle after carbon brush abrasion, so that acting force arm becomes big, i.e.,
Reduce the pulling force of extension spring, but resultant couple is constant, so as to realize carbon brush constant pressure, solves carbon brush of direct current motor initial pressure
Greatly, the inadequate problem of pressure after abrasion, while also increase the effective working depth of carbon brush, extend the carbon brush life-span.Stator module and braking
Coil block forms electromagnetic circuit, and tripping spring presses to drag friction ring and keep plate and motor under the guiding of spring guide finger
Protecgulum, motor is in on-position, after energization, compression brake spring, between drag friction ring and keep plate and front motor cover are formed
Gap, so as to which keep plate can be rotated freely, braking is unclamped, drag ring sheath protection drag ring smooth rotation.
It is of the present utility model to have the advantages that：Parts are few, simple and reliable, excellent through advanced development and trial operation, performance
More, after applied to this DC injection braking motor with constant pressure carbon brush, electrical machinery life increases by 2.5 times, while has power-off brake function.
