Abstract
The invention relates to a reduction gear box in electric machine, including electric machine, reduction box and reduction gear; the reduction gear is set in the reduction box and the first driving component of the reduction gear is connected to the driving shaft of the electric machine, and the electric machine is directly connected to the reduction box by an end cover. Thus, the reduction box and the electric machine share the same end cover, largely simplifying the whole structure to make it simpler and more convenient to manufacture and assemble; synchronously, beneficial to control the sealing and working properties of the whole machine. It sets seal washer between the reduction box and the end cover and sets oil seal at the shaft-outlet stop mouth of the reduction box, reducing the leakage of gear lubricant in the reduction box as far as possible and enhancing the sealing property. The reduction and the end cover are made by precision manufacturing device, ensuring the precise installation driving shafts at all levels of the reduction gear.
Description
Technical field
The present invention relates to a kind of reduction gearbox for electrical motor.
Background technique
In the known technology, as the 70JB type reduction gearbox for electrical motor that our company produces, it comprises motor, deceleration box and reduction gears mechanism; Described reduction gears mechanism adopts level Four to slow down, and is arranged in the described deceleration box, and its first transmission part is connected on the live axle of described motor, output shaft by bearing hinge joint to described casing; Described motor one end is provided with end cap, by being connected on the end cap of described deceleration box behind the pressing plate location.The motor reduction gearbox of this structure, part is more, the structure more complicated, manufacture cost height not only, the manufacturing process complexity, manufacture difficulty is higher, and is unfavorable for controlling the sealing of motor.
Its another defective is that the end cap of speed reducer is gone out the receiving hole that is installed with for the reducing gear bearing by impact style, yet the hole precision that forms with impact style is lower, can cause several gears that are meshed that are articulated on the bearing and transmission shaft to mesh and fit together, and influence smooth and easy that its gear rotates.
Summary of the invention
What the present invention will solve is the prior art above shortcomings, and a kind of follow-on motor reduction gearbox is provided, and is intended to simplified structure, reduces manufacture cost, improves the sealability and the ride quality of complete machine.The technological scheme that addresses the above problem employing is: a kind of reduction gearbox for electrical motor, and it comprises motor, deceleration box and reduction gears mechanism; Described reduction gears mechanism is arranged in the described deceleration box, and its first transmission part is connected on the live axle of described motor, and described motor is directly connected to described deceleration box by end cap.
Reduction gearbox for electrical motor of the present invention, described motor is directly connected to described deceleration box by end cap, and the shared same end cap of casing and motor has been simplified complete machine structure greatly like this, makes manufacturing and assembling more simple and convenient; Simultaneously, this structure also helps controlling the sealability and the ride quality of complete machine.Between described deceleration box and end cap, seal ring is set, on the shaft seam of described deceleration box, oil sealing is set, reduce the seepage of speed reducer middle gear lubricating oil as far as possible, improve sealability.
Described deceleration box periphery is provided with four retaining thread holes, also is provided with corresponding through hole on described end cap, and both pass through screw.Described motor is provided with through hole, is provided with corresponding fixing threaded hole in the bottom of described end cap, and both pass through screw.
As a further improvement on the present invention, described casing and end cap are processed by precise machining equipment, adopt blind hole structure, can guarantee the accurate installation of the transmission shafts at different levels of reduction gear, thereby make the good engagement of maintenance between the adjacent geared parts, it is smooth and easy steady to make entire mechanism rotate, and has promptly guaranteed the runnability of mechanism, the working life of mechanism can be improved again, noise can also be reduced effectively simultaneously.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Embodiment
Shown in the figure, 1_ deceleration box, 2_ tapped hole, the 3_ reducing gear, the 3rd transmission part of 4_ reducing gear, first transmission part of 5_ reducing gear, the first transmission part gear of 6_ reducing gear, second transmission part of 7_ reducing gear, 8_ seal ring, the 9_ end cap, 10_ through hole, 11_ screw, the 12_ motor driving shaft, the 13_ motor, 14_ through hole, 15_ screw, the 4th transmission part of 16_ reducing gear, the 17_ bearing, the output shaft of 18_ reducing gear, 19_ oil sealing, 20_ airtight chamber, 21_ shaft seam, 30_ through hole, 31_ receiving hole.
With reference to Fig. 1, a kind of reduction gearbox for electrical motor, it comprises motor 13, deceleration box 1, end cap 9 and reduction gears mechanism 3.Described reduction gears mechanism 3 is the level Four reduction gears mechanism, is arranged in the airtight chamber between described deceleration box 1 and the end cap 9.This level Four reduction gears mechanism 3 is the standard structure, each grade transmission part is made of transmission shaft, input gear and output gear, the input gear of one-level is meshed with the output gear of upper level, the output gear of one-level is meshed with the input gear of next stage, transmission shaft up and down two ends by bearing fixing on described casing 1 and end cap 9.The input gear 6 of its first transmission part and motor driving shaft 12 engagements.
Described casing 1 and end cap 9 are processed by the CNC precise machining equipment, correspondence is provided with receiving hole 31, and (receiving hole on the end cap 9 is not shown, should be relative with set receiving hole on the casing 1, to guarantee the perpendicularity of every grade of transmission shaft), described receiving hole adopts blind hole structure, Bearing Installation on the transmission shafts at different levels of described reducing gear 3 is in corresponding receiving hole, on the shaft seam 21 of described deceleration box, oil sealing 19 is set, reduce the seepage of speed reducer middle gear lubricating oil as far as possible, improve sealability.Evenly be provided with four retaining thread holes 2 on casing 1 periphery, also be provided with four corresponding through holes 10 on described end cap 9, both are by screw 11 secure fixation.Described end cap is provided with seal ring 8 with the seam that is connected of casing.
Described casing 1 and motor 13 shared same end caps 9 are provided with two installations with through hole 14 on described motor, be provided with two corresponding fixing threaded hole (not shown)s in the bottom of described end cap, and both are fixing by screw 15.Because described end cap 9 and casing 1, end cap 9 and the attachment screw that reaches between the motor 13 do not pass through closed chamber 20, thereby have guaranteed the sealability of complete machine.End cap 9 is provided with through hole 30 in the position corresponding to motor driving shaft 12, protrudes out so far with the live axle 12 of power supply machine.
