As shown in fig. 1, the present application relates to a brake comprising:
a drive mechanism 1, a transmission gear assembly, an output transmission member 2 and an output shaft 3;
the driving mechanism 1 is in driving connection with the transmission gear assembly; and the driving shaft of the driving mechanism 1 is arranged in parallel with the gear shaft in the transmission gear assembly;
the transmission gear assembly is in driving connection with the output transmission member 2 and is used for driving the output transmission member 2 to rotate;
the output transmission member 2 is fixedly connected with the output shaft 3; the output transmission member 2 and the output shaft 3 are arranged above the transmission gear assembly. Generally, a mounting hole matched with the output shaft 3 is arranged in the middle of the output transmission member 2 and is used for being sleeved on one end of the output shaft 3; the other end of the output shaft 3 is also connected with a rocker arm; the rocker arm is also connected with an output pin; and further other products can be driven by the output pin.
Because in this application output driving medium 2 and output shaft 3 locate the top of transmission gear subassembly, consequently for among the prior art because gear shaft parallel arrangement causes the length direction on the size great, can not satisfy the miniaturized condition of requirement of structure, can effectively reduce the length direction's of whole device size.
As shown in fig. 2, in some embodiments, the brake, as described above, further comprises: a magnet 4 and a sensor 5 for sensing the position of the magnet 4;
the magnet 4 is fixedly arranged on the output transmission member 2, and the installation position of the sensor 5 is correspondingly arranged with the magnet 4. Typically, the sensor 5 is disposed forward of the magnet 4, and may be fixed by providing a corresponding fixing frame.
As shown in fig. 1 and 2, in some embodiments, the driving mechanism 1 includes: a motor 101 and a motor gear 102 provided on an output shaft of the motor; the transfer gear assembly includes: a first intermediate gear 6 and a second intermediate gear 7; the first intermediate gear 6 includes: a first large gear 61 and a first small gear 62 provided below the first large gear 61, and the first large gear 61 and the first small gear 62 are coaxially provided; the second intermediate gear 7 includes: a second large gear 71 and a second small gear 72 provided above the second large gear 71, and the second large gear 71 and the second small gear 72 are coaxially provided; in general; the first large gear 61 and the first small gear 62 are coaxially connected and fixed through a first gear pin; the second large gear 71 and the second small gear 72 are coaxially connected and fixed through a second gear pin; and the diameter of the first large gear 61 is larger than that of the first small gear 62, and the diameter of the second large gear 71 is larger than that of the second small gear 72; the motor 101 is a driving device to drive the motor gear 102 to rotate, and the motor gear 102 is fixed on a motor shaft. The motion is transmitted to the output transmission member 2 via said first intermediate gear 6 and second intermediate gear 7 and further via the rocker arm and the output pin to the client (where the client is a controlled end such as a valve). During this time, the rotation angle of the rocker arm is sensed by the sensor 5 by sensing the position of the magnet 4 on the output transmission member 2.
The first large gear 61 is in meshed connection with the motor gear 102, and the first small gear 62 is in meshed connection with the second large gear 71; the second pinion 72 is in meshed connection with the output transmission member 2; in order to minimize the volume of the whole device; when the first pinion gear 62 is in meshed connection with the second large gear 71, the first large gear 61 and the second large gear pin can be selected to have no excessive clearance between the first large gear 61 and the second large gear pin without direct contact by selecting the first large gear 61 and the second gear pin with proper diameters; the second pinion 72 is parallel to the first gearwheel 61 and is disposed above the first gearwheel 61, so that the output transmission member 2 can be positioned above the first gearwheel 61 after the second pinion 72 is engaged with the output transmission member 2.
As shown in fig. 2, 3, 4 and 6, in some embodiments, the brake further includes: a fixed housing; the stationary housing includes: a main housing 8, a lower cover plate 9 arranged below the main housing 8, and an upper cover plate 10 arranged above the main housing 8;
the driving mechanism 1 is arranged in a space formed by the main shell 8 and the lower cover plate 9, and a pipeline for enabling the output end of the driving mechanism 1 to pass through is arranged on the main shell 8; the transmission gear assembly, the output transmission member 2 and the output shaft 3 are arranged in a space formed by the main housing 8 and the upper cover plate 10;
the upper cover plate 10 is provided with a first pipe for mounting the output shaft 3; the output transmission member 2 is rotatably connected to the upper cover plate 10 via the output shaft 3.
In general, the main housing 8, the lower cover plate 9 and the upper cover plate 10 are arranged in accordance with the principle of space saving, i.e. the distance between the main housing 8, the lower cover plate 9 and the upper cover plate 10 is reduced as far as possible without the inner space formed by the main housing 8, the lower cover plate 9 and the upper cover plate 10 affecting the operation of the individual components (the drive mechanism 1, the transmission gear assembly, the output transmission 2 and the output shaft 3) inside. The shape of the main housing 8, the lower cover plate 9 and the upper cover plate 10 are thus adapted to the shape characteristics of the drive mechanism 1, the transfer gear assembly, the output transmission 2 and the output shaft 3 after installation. And preferably, the main housing 8 is further provided with a sensor fixing frame 15 for fixing the sensor 5, and further, the sensor fixing frame 15 may be integrally provided with the main housing 8; the position of the sensor holder 15 is adapted to the position of the magnet 4.
As shown in fig. 2 and 3, in some embodiments, the main housing 8 is provided with a limiting device for limiting the axial movement of the first intermediate gear 6, as in the brake described above; the limiting device comprises: an intermediate gear limiting plate 11 and a limiting plate mounting frame 12 arranged on the main housing 8 and positioned at the edge of the first large gear 61; the limiting plate mounting frame 12 is used for adaptively fixing the intermediate gear limiting plate 11. That is, the first intermediate gear 6 is mounted and fixed to the main casing 8 through the main casing 8, the intermediate gear limiting plate 11, and the limiting plate mounting bracket 12. The intermediate gear limiting plate 11 provides a limiting function of the intermediate gear 1 and a fixation of the first gear pin. Specifically, the intermediate gear limiting plate 11 is provided with a gear pin limiting hole adapted to the first gear pin, so that the first gear pin and the intermediate gear limiting plate 11 can be limited in position after the intermediate gear limiting plate 11 is fixed; the intermediate gear limiting plate 11 is connected with the shell through at least one edge part, and the connection mode can be welding, cementing and the like.
In some embodiments, such as the brake described above, the limiting plate mount 12 includes 3 limiting plate fixtures; the 3 limiting plate fixing pieces are uniformly arranged on the edge of the first large gear 61; the intermediate gear limiting plate 11 is herringbone, and three end points of the intermediate gear limiting plate 11 are used for being connected with the 3 limiting plate fixing pieces in an adaptive mode. Specifically, 3 limiting plate fixing pieces and the herringbone intermediate gear limiting plate 11 limit the first intermediate gear 6, so that a more stable fixing effect can be obtained compared with the fixing of the first intermediate gear 6 through the two limiting plate fixing pieces, and the internal space occupied by the limiting plate fixing pieces and the intermediate gear limiting plate 11 can be effectively reduced compared with the setting of 4 limiting plate fixing pieces.
In some embodiments, as with the brake described above, the output drive 2 is a sector gear; the magnet 4 is arranged at one end of the output transmission member 2, which is not provided with the engagement teeth, in an arc shape. Specifically, by arranging the sector gear, the internal space of the whole device can be reduced on the basis of ensuring that the output shaft 3 can be driven; and generally, the rotation angle of the driving mechanism 1 is adapted to the central angle of the sector gear or the number of the engagement teeth.
In some embodiments, as illustrated in fig. 1, the output transmission 2 is disposed non-coaxially with the first intermediate gear 6, as in the brake described above. The output transmission member 2 and the first intermediate gear 6 are arranged in parallel but not coaxial, and the sensor 5 is laterally arranged in the non-working area of the output transmission member 2, so that the space is greatly utilized, and the volume is reduced. Such a sensor of different axial solutions of the output transmission 2 and the first intermediate gear 6 is difficult to arrange under the sector teeth, sideways as an optimal solution. In the prior art, in order to reduce the volume, the gear structure adopts an arrangement mode of two gears with the same axis, and the structure reduces the volume of an actuator; however, in the coaxial structure, the two groups of gears have larger relative movement speed, the abrasion of the gears is relatively larger, and the accuracy required by the gears is higher; the assembly requirement on the actuator is higher; particularly, when the shell is made of plastic materials, the assembly requirements are increased due to the problems of shrinkage, deformation and the like. The scheme greatly reduces the length of the shaft and simultaneously reduces the process requirements; at the same time, the problem described above is effectively overcome because the life is reduced due to the differential speed of the output transmission member 2 and the first intermediate gear 6 is eliminated.
As shown in fig. 1, in some embodiments, the brake, as described above, further comprises: a bearing unit 13; the external shape of the bearing unit 13 is matched with the first pipeline, and is fixedly arranged in the first pipeline; and the bearing unit 13 is provided with the output shaft 3 in a rolling manner. Specifically, by arranging the bearing unit 13, abrasion of the output shaft 3 and abrasion occurring during rotation can be effectively reduced, and the service life of the output shaft 3 is prolonged.
As shown in fig. 5, in some embodiments, the brake, as described above, further comprises: a wave spring 14; the wave spring 14 is arranged between the driving mechanism 1 and the lower cover plate 9. By providing the wave spring 14, it is difficult to make the size of the driving mechanism 1 completely coincide with the space enclosed between the lower cover plate 9 and the main housing 8, so that the space between the driving mechanism 1 and the lower cover plate 9 can be filled by the wave spring 14 by providing the wave spring 14, thereby ensuring the stability of the driving mechanism 1.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
