Embodiment 1
[0035] A high-efficiency worm gear reducer, the specific structure is as follows Figure 1-6 Shown, comprise gear box, motor 3 and the shaft coupling 6 that transmission connects gear box and motor 3, gear box comprises a box body 1, and a worm wheel and a worm screw that are intermeshedly connected to be arranged in box body 1, worm wheel and The worm adopts ZC tooth shape for meshing connection. The center distance between the two shafts is 100mm. The worm adopts 2 worms. The worm gear is installed horizontally in the box 1 through the worm shaft 7, and the worm is installed vertically on one side of the box 1. The motor 3 is a four-pole or six-pole motor with a power of 0.55kW to 7.5kW. The coupling 6 connects the output end of the motor and the end of the worm protruding from the box. A braking unit is provided outside the coupling 6. The braking unit Including connecting body 2, brake wheel 13 located inside connecting body 2, electromagnet 5 and braking arm 4 located out...
Embodiment 2
[0042] A high-efficiency worm gear reducer, the specific structure is as follows Figure 1-6 As shown, the motor 3 is a six-stage motor with a power of 7.5kW. The position where the two ends of the worm are in contact with the inner side of the box body 1 is supported by a bearing. The bearing adopts a tapered roller bearing with a large contact angle. A pair of tapered roller bearings are installed face to face at both ends of the worm; the bearing installed at the upper end of the worm is lubricated by an oil bath, which can make the lubricating oil rise to the upper bearing, and the outer ring of the bearing has 1 / 3~1 / 2 width in the oil bath middle. The position where the two ends of the worm gear shaft 7 are in contact with the inner side of the casing 1 is provided with a bearing layer for support, and the bearing adopts a tapered roller bearing with a medium contact angle. The cooling ribs 8 have a draft angle of 3° and a width of 10 mm. Other structures are the same a...
Embodiment 3
[0044] A high-efficiency worm gear reducer, the specific structure is as follows Figure 1-6 As shown, the motor 3 is a four-pole or six-pole motor with a power of 3.4kW. The position where the two ends of the worm are in contact with the inner side of the box body 1 is supported by bearings, and the bearings are angular contact ball bearings with a large contact angle. A pair of angular contact ball bearings are installed face-to-face at both ends of the worm; the bearings installed at the upper end of the worm are lubricated with an oil bath, which can make the lubricating oil rise to the upper bearing, and the outer ring of the bearing has 1 / 3~1 / 2 width in the oil bath middle. The position where the two ends of the worm gear shaft 7 are in contact with the inner side of the casing 1 is provided with a bearing layer for support, and the bearing adopts a tapered roller bearing with a medium contact angle. The cooling ribs 8 have a draft angle of 2° and a width of 7 mm. Othe...
