Abstract
The invention relates to a speed reducer capable of achieving the function by a differential device comprising worm gears and bevel gears. The speed reducer comprises a box body, worm-gear worm sets, main shafts, a rotary arm and more than one bevel gear; the main shafts are supported in the box body; the rotary arm is in cup joint with the main shafts through keys; the more than one bevel gear is in cup joint with the rotary arm through a bearing; the worm-gear worm sets comprise a left worm gear, a right worm gear, a left worm and a right worm; the left worm and the right worm are respectively meshed with the left worm gear and the right worm gear; the left worm gear and the right worm gear are respectively in cup join with the main shafts at two sides of the rotary arm through a bearing; and the left worm gear and the right worm gear are respectively meshed with more than one bevel gear. The left and right worm-gear worm sets are adopted to be meshed with the bevel gears, so that the bevel gears revolve while rotating, thus the main shafts are driven by the rotary arm to realize output. The speed reducer has the advantages of compact structure, small volume, high transmission power, large torque, high bearing, less abrasion and long service life, and the left and right worm-gear worm sets can be switched to operate.
Description
Technical field
The present invention relates to a kind of worm gear umbrella gear differential motion speed reducer.
Background technique
Speed reducer has deceleration and increases the torque function, is applied in the conversion equipment of speed and moment of torsion, therefore in the transmission system of various machinery, can see its trace.At some to speed reducer structure and the strict occasion of reduction speed ratio, the superiority of worm-gear speed reducer ultra-traditional gear reduction unit far away, the worm-gear speed reducer reduction speed ratio is bigger; During worm-gear speed reducer work; Worm screw is the filing worm gear ceaselessly, makes worm gear produce wearing and tearing, after long-term the use; The worm gear wearing and tearing are big, have a strong impact on working life.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of compact structure, can effectively reduce the worm gear wearing and tearing, the worm gear umbrella gear differential motion speed reducer that increases the service life.
The technological scheme that the present invention adopts is: a kind of worm gear umbrella gear differential motion speed reducer; Comprise casing, worm and gear group and main shaft; Main shaft supporting is in casing; It is characterized in that also comprising a pivoted arm and the umbrella gear more than, pivoted arm is socketed on the main shaft through key, and the umbrella gear more than is connected on the pivoted arm through bearing housing; Said worm and gear group comprises left and right worm gear and left and right worm screw, and left and right worm screw meshes left and right worm gear respectively, and left and right worm gear is connected on the main shaft of pivoted arm both sides through bearing housing respectively, and left and right worm gear all meshes the umbrella gear more than.
Further, said umbrella gear more than is connected on the pivoted arm through bearing housing and evenly is provided with around main shaft.
Again further, be socketed with two umbrella gear around the main shaft symmetry on the said pivoted arm.
During speed reducer work, motor is taken over a worm screw, when left worm screw input; Left side worm gear is around main axis rotation, and left worm gear meshes the umbrella gear more than and drives its rotation, because right worm gear and right worm screw are not worked; The self-locking performance of right worm gear, umbrella gear can't drive right worm gear rotation, therefore in the umbrella gear rotation, revolve round the sun around main shaft again; The umbrella gear revolution drives pivoted arm around main axis rotation, thereby realizes main shaft output; When right worm screw was imported, working state was opposite with above-mentioned left worm screw input.But the alternation of left and right worm and gear group avoids independent worm and gear group leader phase service wear seriously to cause damaging, and the worm gear long service life reduces user cost.
Revolution when the present invention adopts the common meshing bevel gear of left and right worm and gear group to make the umbrella gear rotation; Thereby drive main shaft output through pivoted arm, its compact structure, volume is little; Transmitted power is big, moment of torsion is big, carrying is big.; The changeable work of left and right worm and gear group, the speed reducer service wear is little, long service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: casing 1, main shaft 2, pivoted arm 3, umbrella gear 4, left worm gear 5, left worm screw 6, right worm gear 7, right worm screw 8.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Shown in Figure 1, a kind of worm gear umbrella gear differential motion speed reducer casing 1, main shaft 2, pivoted arm 3, umbrella gear 4, left worm gear 5, left worm screw 6, right worm gear 7 and right worm screw 8.Main shaft 2 is supported in the casing 1, and through key socket one pivoted arm 3, the two ends of pivoted arm 3 are arranged with two umbrella gear 4 on the main shaft 2; Left and right worm gear 5,7 is connected on the main shaft 2 of pivoted arm 3 both sides through bearing housing respectively, and left and right worm screw 6,8 meshes left and right worm gear 5,7 respectively, and left and right worm gear 5,7 all meshes two umbrella gear 4.
