Abstract
The utility model relates to a speed reducer of a worm gear bevel gear differential device, which includes a box body, a worm gear and worm group and a main shaft, wherein the main shaft is supported in the box body; the speed reducer also includes a rotating arm and more than one bevel gear; the rotating arm is sleeved on the main shaft through a key; the more than one bevel gear is sleeved on the rotating arm through a bearing; the worm gear and worm group includes a left worm gear and a right worm gear, a left worm and a right worm; the left and the right worms are respectively meshed with the left and the right worm gears; the left and the right worm gears are sleeved on the main shaft on the two sides of the rotating arm through the bearing; and both the left and the right worm gears are meshed with more than one bevel gear. In the utility model, the left and the right worm gears as well as the left and the right worms are jointly meshed with the bevel gears, so that the bevel gears can perform autorotation and revolution simultaneously, and the main shaft is driven to output through the rotating arm, the speed reducer has compact structure, small volume, big transmission power, big torque and big load bearing, the left and the right worm gears as well as the left and the right worms can operate in a switching manner, the operation abrasion of the speed reducer is small, and the service life is long.
Description
Technical field
The utility model 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 utility model 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 utility model 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 utility model 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 the utility model structural representation.
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 utility model 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.
