Abstract
The invention relates to a planet carrier for an output end of a reducer. The planet carrier is characterized by comprising a first rack body and a second rack body, wherein an output shaft which is perpendicular to the first rack body and is integrated with the perpendicular is arranged at a central position on one side of the first rack body; four circular grooves and four screw holes are uniformly distributed on the surface of the other side of the first rack body close to the outer edge along the circumferential direction; four bosses are uniformly distributed on the surface of one side of the second rack body along the circumferential direction; screw holes are formed at central positions of the bosses; circular through holes are formed between every two adjacent bosses; the grooves on the first rack body correspond to the through holes on the second rack body one by one; a gear shaft is arranged on each pair of grooves and the through holes; the screw holes on the first rack body correspond to the screw holes on the bosses of the second rack body one by one and are fixed together through the screws. By adoption of the planet carrier, the gear shaft does not tilt, the planet carrier has high rigidity, the fit length and magnitude of interference of the gear shaft and the planet carrier hole are not required to be checked, the processing and assembling operations are relatively simple, and the phenomenon that the noise of the reducer is increased or the temperature of the reducer is raised is avoided.
Description
Technical field
The present invention relates to a kind of speed reducer and use planet carrier, is the planet carrier that both arms support that has that is used on the planet cut speed reducer output terminal specifically.
Background technique
At present; The planet carrier that applies on the speed reducer output terminal is traditional single arm type planet carrier; This planet carrier is evenly equipped with four gear shafts on the surface of its support body one side; Gear shaft is used to install gear, and the support body centre bit is equipped with circular hole, is used to install output shaft on the circular hole or is transmission with output shaft cooperate.The shortcoming of this structure is that planet carrier is in vertical layout in use usually; Gear is installed on the gear shaft of planet carrier and is in cantilever position all the time; Owing to receive the influence of gear deadweight and other external force, use backgear axle meeting run-off the straight for a long time, cause its rigidity to descend.And this structure also need be checked the length of thread engagement and the magnitude of interference in gear shaft and planet carrier hole when design and installation, and this planet carrier of side can't normal operation.In addition, planet carrier and output shaft are split-type structural, and it need use spline when connecting or through gear transmission, its processing and assembling work are comparatively complicated, and meeting in service causes the speed reducer noise to increase or temperature raises.
Summary of the invention
The problem that the present invention will solve provides a kind of speed reducer output terminal and uses planet carrier; Adopt this planet carrier; Gear shaft can run-off the straight, and good rigidly need not to check the length of thread engagement and the magnitude of interference in gear shaft and planet carrier hole; And processing and assembling work are simple relatively, can not cause the speed reducer noise to increase or the temperature rising.
For addressing the above problem, take following scheme:
A kind of speed reducer output terminal of the present invention is to comprise first support body and second support body with the characteristics of planet carrier.Said first support body is discoideus; The one of which side surface has the output shaft of perpendicular and one at center position; Its opposite side surface is at groove and four screws of circumferentially being evenly equipped with four circles near the outer edge edge; Groove and screw are separation, and the center of circle of four grooves and four screws is all on a circle.Said second support body is circular, and the one of which side surface is along circumferentially being evenly equipped with four boss, and the center position of boss has screw.Between every adjacent two boss circular through hole is arranged all on said second support body, the center of circle of the screw on through hole and the boss is all on a circle.Groove on said first support body is corresponding one by one with lead to the hole site on second support body, and each is to being equipped with a gear shaft on groove and the through hole.Screw on said first support body is corresponding one by one with screwhole position on the second support body boss, and relative second support body of the reeded one side of first support body has the one side of boss to be fixed together through the screw on screw and two support bodys.
Further improvement project of the present invention is that the cross section of the boss on said second support body is fan-shaped, and the outward edge of boss flushes with the second support body outward edge, and the inward flange of boss is near the edge of center hole on second support body, thereby can improve the steadiness of planet carrier.
Take such scheme, have the following advantages:
Because a kind of speed reducer output terminal of the present invention is formed by connecting first support body and second support body with planet carrier; Gear carrier is fixed between first support body and second support body, and therefore, the gear shaft in this structure is in the both arms holding state; Gear is installed on the gear shaft; Even if receive the influence of gear deadweight and other external force, gear shaft can run-off the straight yet, and its rigidity is better.And, because the gear shaft among the present invention is in the state that both arms support, all need not to check the length of thread engagement and the magnitude of interference in gear shaft and planet carrier hole during design and installation.In addition; Because a kind of speed reducer output terminal of the present invention uses the output shaft of planet carrier and first support body to be integral structure, can save the installation exercise of output shaft and support body, reduce the difficulty of processing and assembling work; And integrative-structure can not produce noise when operation, also can not cause temperature to raise.

Embodiment
As shown in Figures 2 and 3, a kind of speed reducer output terminal of the present invention comprises first support body 2 and second support body 6 with planet carrier.Said first support body 2 is discoideus, and the one of which side surface has perpendicular output shaft 1 at center position, and the output shaft 1 and first support body 2 are integrative-structure or adopt the mode of welding to link together.The opposite side surface of first support body 2 is at groove 3 and four screws of circumferentially being evenly equipped with four circles near the outer edge edge, and groove 3 is separation with screw, and the center of circle of four grooves 3 and four screws is all on a circle.Said second support body 6 is circular, and the one of which side surface is along circumferentially being evenly equipped with four boss 7, and the center position of boss 7 has screw.The cross section of boss described in the present embodiment 7 is fan-shaped, and the outward edge of boss 7 flushes with second support body, 6 outward edges, and the inward flange of boss 7 is near the edge of center hole on second support body 6.Every 7 of adjacent two boss all have circular through hole 5 on said second support body 6, and the center of circle of the screw on through hole 5 and the boss 7 is all on a circle.Groove 3 on said first support body is corresponding one by one with through hole 5 positions on second support body, and each is to all being equipped with a gear shaft 4 on groove 3 and the through hole 5.Screw on said first support body 2 is corresponding one by one with screwhole position on the second support body boss 7, and relative second support body 6 of the one side of first support body 2 fluted 3 has the one side of boss 7 to be fixed together through the screw on screw and two support bodys.
