Abstract
The utility model discloses a braking device for a motor, which comprises a spring, a sliding block, an oscillatory spline housing, a dynamic friction wafer and a static friction wafer which are sheathed on a motor spline shaft in turn. The spring and the sliding block are arranged at the inner side at the back end cover of the motor. The dynamic friction wafer and the static friction wafer are arranged at the outer side at the back end cover of the motor. The oscillatory spline housing is arranged in a bearing hole of the back end cover. The left end and the right end of the oscillatory spline housing respectively correspond to the sliding block and the dynamic friction wafer. Compared with the traditional inlaid braking device, the utility model has the advantages of stable performance, long service life and adjustable brake moment.
Description
Technical field
The utility model relates to dynamic braking device, exactly is the brake apparatus that is used for other magneto.
Background technology
Traditional dynamic braking device is located at motor casing inside, cause the friction plate powder in housing, to fly upward, hoard, rotor, bearing are under the dust environment when work, thereby greatly reduce motor properties and useful life, and the friction plate of brake apparatus can only be a single chip architecture, and braking moment is fixing can not be adjusted.
The utility model content
At the deficiency that prior art exists, the utility model aims to provide the adjustable dynamic braking device of a kind of stable performance, long service life and braking moment.
The technical solution adopted in the utility model is:
A kind of dynamic braking device, comprise the spring, slide block, play spline housing, movable friction plate and the static friction sheet that are sleeved on successively on the motor splined shaft, spring and slide block are positioned at the inboard of back end cover for motor, movable friction plate and static friction sheet are positioned at the outside of back end cover for motor, the play spline housing is arranged in the dead eye of rear end cap, and its left and right two ends correspond respectively to slide block and movable friction plate.
Described movable friction plate and static friction sheet adopt single chip architecture.
Described movable friction plate and static friction sheet adopt multi-sheet structure.
Described movable friction plate and static friction sheet are planar friction sheet or conical surface friction sheet.
Described spring is arranged in the inner fovea part of slide block left end.
The profile of tooth of described motor splined shaft is involute shape, rectangle or circular arc, and the spline shape of slide block, play spline housing and movable friction plate is complementary with it.
Described motor splined shaft end is provided with the adjustment nut.
Described back end cover for motor is sleeve shaped, and movable friction plate and static friction sheet all are positioned at its inside, and the spline of static friction sheet periphery is entrenched in the spline of its inwall.
The brake portion of this brake apparatus is arranged on the outside of motor casing, rotor and bearing are positioned at the rear end cap inboard, friction plate is positioned at the rear end cap outside, this structure spaced apart from each other, can guarantee that powder that friction plate produces can not influence the operate as normal of rotor, bearing, solve all drawbacks that brake apparatus is positioned at motor internal.In addition, its friction plate promptly can adopt single chip architecture, also can adopt multi-sheet structure, and shape can be the plane, also can be the conical surface, can adjust skidding moment.
Description of drawings
Fig. 1 is the internal structure schematic diagram of the utility model dynamic braking device.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1---motor shaft 2---spring
3---slide block 4---bearing
5---back end cover for motor 6---play spline housing
7---movable friction plate 8---static friction sheet
9---adjusting nut 10---rotor
11---stator
As shown in Figure 1, the right-hand member of motor shaft 1 is the splined shaft that prolongs, on the bearing pedestal in the middle of the back end cover for motor 5 splined shaft bearing 4 is installed, spring 2, slide block 3, play spline housing 6, movable friction plate 7 and static friction sheet 8 are sleeved on the splined shaft successively, spring 2 and slide block 3 are positioned at the inboard of back end cover for motor 5, spring 2 is inserted in the inner fovea part of slide block left end, movable friction plate 7 and static friction sheet 8 are positioned at the outside of back end cover for motor 5, play spline housing 6 is arranged in the dead eye of rear end cap, its left side, right two ends correspond respectively to slide block 3 and movable friction plate 7, back end cover for motor 5 is sleeve shaped, movable friction plate 7 and static friction sheet 8 all are positioned at its inside, the spline of static friction sheet 8 peripheries is entrenched in the spline of its inwall, the splined shaft end is provided with adjusts nut 9, the profile of tooth of splined shaft is involute shape, rectangle or circular arc, slide block 3, the spline shape of play spline housing 6 and movable friction plate 7 is complementary with it.
This brake apparatus is mainly used in the asynchronous motor side magnetic braking, its operation principle is: during outage, magnetic pull disappears, and slide block moves right under the spring pressure effect, promoting movable friction plate by the play spline housing moves axially, contact with the static friction sheet, realize braking, during energising, the rotor magnetic pull attracts slide block compression spring to be moved to the left, pressure disappears between the dynamic and static friction plate, produces the gap, so movable friction plate is with rotor rotation.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.For example movable friction plate and static friction sheet adopt single chip architecture, perhaps adopt planar friction sheet or conical surface friction sheet or the like.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection range.
