Background technique
The individual components that retarder is a kind of gear transmission by being enclosed in stiff case, worm drive, pinion-endless screw transmission form, is commonly used for the speed reduction gearing between driving link and working machine.Between prime mover and working machine or actuator, play coupling rotating speed and transmitting torque, apply very extensive in modern mechanical.
Traditional retarder, reduction gearing mechanism is provided with in speed reducer, at speed reducer output terminal, end cap is set, in end cap, bearing support is set, output shaft to be arranged in bearing support and to be connected with driving mechanism in speed reducer, but be connected by ring supporting base between existing bearing support with end cap inwall, between bearing support and end cap inwall, stiffening rib is set, but due to output shaft carrying torque larger, the torsion causing the joint of stiffening rib and bearing support and end cap to be born is larger, easy fracture damage, whole end cap is caused to need again to repair or scrap, cost is increased.
Summary of the invention
The deficiencies in the prior art in view of the above, the object of the present invention is to provide a kind of structural strength high, carrying torque capacity chamber, and non-damageable speed reducer exports end cap.
For achieving the above object and other relevant objects, the invention provides a kind of speed reducer and export end cap, comprise end cap body, the supporting base of ring, bearing support, described supporting base is fixedly mounted in end cap inner body wall, described bearing support is arranged in supporting base, many stiffening ribs are provided with between described bearing support outer wall and end cap inner body wall, be fixed on bottom this stiffening rib on supporting base, described stiffening rib two ends are fixed with bearing support outer wall and end cap inner body wall respectively, the end at described strong muscle two ends is provided with buildup piece, this buildup piece is fixedly connected with end cap inner body wall with described bearing support outer wall.
Adopt said structure, owing to being provided with stiffening rib and the joint of stiffening rib and end cap body and bearing support be provided with buildup piece, the intensity of stiffening rib and end cap body and bearing support joint can be improved further, the torsion of greater strength can be born, not easy-rupturing, improve the intensity that speed reducer exports end cap, extend its working life.
Also the buildup piece of evagination is provided with between described stiffening rib both sides and supporting base.The join strength of stiffening rib and supporting base is strengthened by this buildup piece.
Described buildup piece and stiffening rib one-body molded, one-body molded intensity is higher.
Described buildup piece is stretched out by stiffening rib and is formed, and the two ends of stiffening rib are increased to end face gradually by end, and the both sides of described stiffening rib are increased to bottom gradually by top.This structure makes stiffening rib and bearing support outer wall, surface of contact between end cap inner body wall and supporting base larger, makes it connect more firm.
Described stiffening rib and bearing support outer wall, equal rounding off between end cap inner body wall and supporting base.
The cross section profile of described stiffening rib is that middle high both sides are low, and the curve reduced gradually by centre to both sides.
The top indent camber of described stiffening rib, this structure is when not affecting stiffening rib intensity, reduces material, with cost-saving.
Described stiffening rib is connected with the first surface of supporting base, is provided with polylith stiffening plate, this stiffening plate offers destressing hole between second of supporting base and end cap inner body wall.Arrange the intensity between stiffening plate raising supporting base and end cap body, the effect reducing stress can be played in destressing hole, avoids stress to concentrate and causes fracture.
Described stiffening rib and stiffening plate are uniformly distributed along end cap body circumference.
Described end cap body is cylindric, and described end cap body outer wall and two ends are provided with mounting hole, and described bearing support end face is provided with attachment hole.Mounting hole and attachment hole are used for being connected with outside appurtenances.
As mentioned above, the invention has the beneficial effects as follows: the intensity that improve bearing support and end cap body by arranging stiffening rib and buildup piece, increase the bearing capacity of bearing support, make the joint of stiffening rib and bearing support and end cap body not easy-rupturing stiffening plate be set improve intensity between supporting base and end cap body, the effect reducing stress can be played in destressing hole, avoid stress to concentrate and cause fracture, thus the bulk strength making speed reducer export end cap is improved, extend the working life that speed reducer exports end cap.
