Detailed Description
The conception, specific structure, and technical effects produced by the present invention will be clearly and completely described below with reference to the embodiments and the drawings to fully understand the objects, features, and effects of the present invention. It is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present invention based on the embodiments of the present invention. In addition, all coupling/connection relationships mentioned herein do not refer to direct connection of the components, but rather, refer to the fact that a more optimal coupling structure may be formed by adding or subtracting coupling aids depending on the particular implementation.
Referring to fig. 1 to 4, an oblique-tooth planetary gear speed-reducing roller shutter head comprises a mounting seat 10, a planetary gear mechanism and a head cover 7, wherein the planetary gear mechanism comprises a sun gear 1 provided with oblique teeth, a sprocket 2 internally provided with oblique teeth, a plurality of oblique-tooth planetary gears 3 and a planetary gear frame 4, all the oblique-tooth planetary gears 3 are meshed with the inner side of the sprocket 2, one end of the sun gear 1 is fixed on the mounting seat 10, and the head cover 7 is mounted on the planetary gear frame 4. The pull beads are matched with the chain wheel 2, and the pull beads are pulled to enable the chain wheel 2 to rotate. The inner side helical teeth of the chain wheel 2 are meshed with a plurality of helical tooth planet gears 3, and the helical tooth planet gears 3 are meshed with a fixed sun gear 1 at the same time, so that a planet carrier 4 fixed on the end surface of the helical tooth planet gears 3 rotates around the sun gear 1 as a circle center. The planetary gear mechanism is used for transmission, so that the speed reduction rotation of the head cover 7 can be realized, and the sun wheel 1, the chain wheel 2 or the helical planet wheel 3 with different specifications can be selected to be meshed according to different requirements, so that different speed reduction ratios are generated. Because all gears in the planetary gear mechanism are meshed through helical teeth, the intermittent collision of tooth surfaces can be generated when the gears are different from the common cylindrical gears, so that the noise during operation is greatly reduced, the operation is smoother and more stable, and the bearing capacity is higher.
Further as a preferred embodiment, a main body shaft 11 is disposed at the other end of the sun gear 1, the main body shaft 11 penetrates through the brake head cover 7, and a braking device is disposed between the main body shaft 11 and the brake head cover 7. The braking device prevents the brake cover 7 from being used as a driving piece to drive the sprocket 2 to rotate, and the movement state of the brake cover 7 can only be determined by the movement state of the sprocket 2.
Further as a preferred embodiment, the braking device comprises a torsion spring 5 and a rotating arm 41 arranged on the planet carrier 4, both ends of the torsion spring 5 are outwards bent to form protruding parts, an opening is formed in the side face of the rotating arm 41, the rotating arm 41 is sleeved on the outer side of the torsion spring 5, and both ends of the opening can be connected with the protruding parts at both ends of the torsion spring 5 respectively. The end surfaces of the two ends of the opening are opposite to the unlocking surfaces 51 of the two protruding parts. When the rotation arm 41 is the driving member, one side of the opening of the rotation arm 41 rotates and contacts the unlocking surface 51 of the projection of the torsion spring 5. The inner diameter of the torsion spring 5 becomes larger, a gap exists between the torsion spring 5 and the main body shaft 11, namely, the surface friction force between the torsion spring 5 and the main body shaft 11 is smaller, namely, the torsion spring 5 is in an unlocking state, and the head cover 7 can rotate freely.
Further as a preferred embodiment, the patch 71 is disposed on the inner wall of the head cover 7, and two ends of the patch 71 can be respectively connected with the protruding parts at two ends of the torsion spring 5. The two end surfaces of the patch 71 are opposite to the locking surfaces 52 of the two protruding parts. When the head cover 7 is the active member, the patch 71 inside the head cover rotates and contacts the locking surface 52 of the protruding portion of the torsion spring 5. The smaller the inner diameter of the torsion spring 5, the greater the friction with the surface of the sleeve 6, the tighter the locking will be, and therefore the head cover 7 cannot rotate freely. In addition, the patch 71 also prevents the head cover 7 from crushing the torsion spring 5.
Further as a preferred embodiment, the braking device further comprises a sleeve 6 sleeved outside the main body shaft 11, and the sleeve 6 is arranged between the main body shaft 11 and the torsion spring 5. Since the torsion spring 5 is usually held tightly against the main body shaft 11 when the torsion spring is used for the braking operation, the main body shaft 11 is easily worn, and the sleeve 6 is provided outside the main body shaft 11. Preferably, the sleeve 6 is made of a wear-resistant metal material, protecting the main body shaft 11 from wear, thereby ensuring the fitting accuracy of the parts.
Further as a preferred embodiment, the top end of the main body shaft 11 is connected with a locking cap 8, a plurality of step blocks 72 are circumferentially arranged around the main body shaft 11 on the top end surface of the head cover 7, and the bottom surface of the locking cap 8 can be connected with the shoulders of the step blocks 72. The locking cap 8 is fixed on the top end of the main body shaft 11 and limits the head cover 7.
Further as a preferred embodiment, a gap is provided between the bottom surface of the locking cap 8 and the shoulder of the step block 72. After the assembly of the head-making structure is completed, the head-making cover 7 can be pulled in the direction of the locking cap 8, so that a proper gap is generated between the planet carrier 4 and the mounting seat 10, and the pull bead is mounted on the chain wheel 2.
While the preferred embodiments of the present application have been illustrated and described, the present application is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present application, and these equivalent modifications and substitutions are intended to be included in the scope of the present application as defined in the appended claims.
