Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, and as shown in fig. 1-3, a compact speed reducer casing comprises a casing 1, wherein a worm cavity 2 is arranged at the upper part in the casing 1, a worm wheel cavity 3 is arranged at the lower part in the casing 1, and the worm cavity 2 is communicated with and perpendicular to the worm wheel cavity 3; the top end of the worm cavity 2 is communicated with a motor cavity 10. The motor is installed in the motor cavity 10 and fixedly connected with the worm in the worm cavity 2, the teeth of the worm are meshed with the teeth in the worm wheel cavity 3, the motor drives the worm to rotate rapidly, the worm rotates a circle of worm wheels, one tooth is rotated forwards, and then speed reduction is achieved. And the transmission ratio can be adjusted by adjusting parameters such as the tooth numbers of the worm wheel and the worm.

Two ends of the worm cavity 2 are provided with worm connecting holes 4, and two ends of the worm are rotatably connected with the worm connecting holes 4. And worm wheel connecting holes 5 are formed in two ends of the worm wheel cavity 3, and two ends of the worm wheel are rotatably connected with the worm wheel connecting holes 5. The worm wheel connecting hole 5 at one end of the worm wheel cavity 3 is fixedly connected with an end cover 8, and the worm wheel connecting hole 5 at the other end of the worm wheel cavity 3 is connected with a belt pulley 9. The end cover 8 and the belt pulley 9 seal the worm wheel connecting hole 5, the worm wheel is fixedly connected with the belt pulley 9, and the worm wheel drives the belt pulley 9 to rotate, so that transmission in the vertical direction is realized through the belt.

And a reinforcing rib 6 is arranged on one side in the worm wheel cavity 3. The strength of the shell is enhanced, and the service life is prolonged.

An oil injection port 14 is formed in the wall of one side of the worm gear cavity 3, and a liquid level window 7 is formed in the wall of the other side of the worm gear cavity 3. The oil level in the box body 1 is observed through the liquid level window 7, so that lubricating oil can be conveniently added at any time.

The upper part of the box body 1 is provided with at least one heat dissipation hole 11, so that heat generated in the box body 1 is released at any time, mechanical faults are prevented, and the service life is prolonged.

The base 12 is arranged at the bottom of the box body 1, so that the speed reducer is more stable.

And a motor mounting plate 13 is arranged at the top end of the motor cavity 10 and used for fixing a motor.

In the embodiment, the box body 1 is provided with the motor cavity 10 communicated with the worm cavity 2, the motor is arranged in the speed reducer shell, the structure is compact, the occupied space of the speed reducer shell and the motor can be saved, and the use requirement of small-space equipment is met; a worm wheel connecting hole 5 at the other end of the worm wheel cavity 3 is connected with a belt pulley 9, and a worm wheel is directly and fixedly connected with the belt pulley 9, so that transmission in the vertical direction is realized; the reinforcing ribs 6 are arranged in the box body 1, so that the strength of the shell is improved, and the service life of the speed reducer shell can be prolonged from 3 ten thousand hours to 3.5 ten thousand hours; the motor is arranged in the motor cavity 10 to enable the motor to be more stable, so that the working noise is lower after the worm wheel, the worm, the motor and the like are installed.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
