Description

The main shaft braking construction of direct-driving torque motor device

Technical field

The present invention relates to a kind of main shaft braking construction, be meant a kind of main shaft braking construction of direct-driving torque motor device especially.

Background technology

Motor apparatus now is more and more many in the application of industrial aspect, main device kind has external rotor, internal rotor or the like, except high precision effect as the feeding transmission, it has more that the frictional wear rate is little, energy conversion rate is high and advantage such as noise is little, therefore, motor apparatus is not sayed yet and can be explained for importance such as various commercial Application facility now.

Present direct-driving torque motor device is useful on the part device drives, for example: automation equipment, index dial and various toolroom machine; The main shaft of common direct-driving torque motor device is positioned at internal rotor central authorities merely, and utilizes the rotation control main shaft of direct-driving torque motor; Though previous designs has been obtained practicality, still can exist by defectiveness after the practicality:

One, the brake of the common direct-driving torque motor device of this kind is to utilize the power of rotary distance motor to stop main shaft naturally, because main shaft still had rotating inertia force when control stopped, not way brake fast immediately, when being applied to the product of all kinds of angle controls, rotating speed control, precision control, still have the defective in the control;

They are two years old, key is when to be common direct-driving torque motor stop at unspecified angle after rotating, working substance or cutter that its main shaft drives run out of steam immediately, as losing supporting strength, do not have this moment working substance or cutter power just to support and to bear bigger cutting strength at all, so when common direct-driving torque motor stops at unspecified angle after rotating, do not have lock to pay power to the thing that driven on its main shaft.

In order effectively to solve foregoing problems, the present invention is based on over the research and development technology and the experience of being accumulated in the activation motor apparatus field, the angle of paying power from the lock of can braking immediately, promote adds research and development again, develops the main shaft braking construction that a kind of brand-new direct-driving torque motor device finally.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of main shaft braking construction of direct-driving torque motor device, and it can realize that main shaft brakes fast, has strong lock and pays a power.

For solving the problems of the technologies described above, the main shaft braking construction of direct-driving torque motor device of the present invention, it comprises: a body; Turn apart from motor always, be installed in this body; One main shaft is installed on this and directly turns in motor; An and brake device, be installed between body and the main shaft, tool one brake grease chamber in this brake device, and brake grease chamber respective major axes direction is provided with brake distortion wall, utilize the high pressure order brake distortion wall distortion of brake grease chamber, and protrude the extruding main shaft and brake with the distortion of brake distortion wall.

Simple in structure and the assembling of the present invention can stop, accurate control easily immediately, can make main shaft and brake fast.

Because the present invention utilizes this ring-like brake grease chamber brake distortion wall distortion, reaches the purpose of extruding main shaft braking; So the present invention is when braking, be subjected to the braking strength of distortion extruding of distortion wall of the structure on main shaft and the main shaft supports, and therefore, the structure on main shaft of the present invention and the main shaft has strong lock and pays a power.

What deserves to be mentioned is that ring-like brake grease chamber is positioned at a brake seat, this brake seat comprises a Building L piece and a capping, and both utilize O type ring sealing combination, reaches the effect of simplified structure, avoids because of making the difficult cost of manufacture that improves in ring-like brake grease chamber;

And the brake seat is fixed in the body front end, and this ring-like grease chamber of brake seat collocation is equipped with several O type rings, can prevent that by this brake fluid is excessive, when the compressed oil of ring-like grease chamber need be changed, can outwards be released by the oil pressure interface.

In addition, aforementioned brake device can be to be assembled between body and main shaft, and the oil pressure interface that utilizes base side to offer is connected the brake grease chamber, and outwards connects pressure source with the oil pressure interface, make brake grease chamber's controlled-deformation or recovery at any time, and reach the main shaft brake effect of exerting pressure.

In addition, because the present invention is modularity removably, so the bearing, bearing pedestal quantity, position and the feature of the present invention that are configured between this body and the main shaft are irrelevant, so the present invention can simple and easyly apply mechanically bearing, the bearing pedestal of different size, different shape, for example general ball, roller bearing design can become the element that a kind of the present invention selects for use.
