Abstract
The utility model discloses a spiral bevel gear for a speed changing box of a cabling machine. The spiral bevel gear comprises a conical gear body, wherein one end face of the gear body is a small end, the other end face of the gear body is a big end, the center of the gear body is provided with a mounting hole in which a keyway is arranged, 33 gear teeth are uniformly distributed on a conical surface of the gear body, each gear tooth has a left-handed spiral direction and is 6 in modulus and 20 degrees in spiral angle, an included angle between a tooth face constituted by the conical surface or the topmost points of the gear teeth and an end face of the small end of the gear body is controlled to be between 42 degrees and 46 degrees, and the width of the tooth face is 35-45mm. The spiral bevel gear disclosed by the utility model is reasonable in structural design, the gear is redesigned to control the teeth number, modulus, spiral angle, and included angle between the conical surface and the end face of the gear, the breakage rate, distortion rate and tooth crack rate of a tooth profile of the gear are reduced greatly, and the gear is effectively increased in practicability and prolonged in service life.
Description
Technical field:
The utility model relates to gear, relates in particular to a kind of cable-forming machine gearbox and uses helical bevel gear.
Background technique:
Regular meeting damages when in the use of several years, having in the strand cage main transmission gearbox driving gear all the time for the 1+4/2000 cable-forming machine.Rate of breakdown is higher when particularly running into electric cable with large cross-section stranding twisted wire.The gear teeth that are mainly reflected in a pair of main transmission circular cone straight-tooth gear in the gear-box can damage.The flank profil of gear can fracture, twist, collapses tooth etc., causes this equipment not run well, and production work is often cut off.
For the normal operation of support equipment, improve usage ratio of equipment, for enterprise's create beneficial result constantly, must carry out technological transformation to this equipment, make it reduce rate of breakdown, reduce the expense of device maintenance.
The model utility content:
In order to solve the existing technology problem, the purpose of the utility model provides a kind of cable-forming machine gearbox and uses helical bevel gear, effectively solves the problem that gear-profile can fracture, twist, collapses tooth.
The technological scheme of the utility model is following:
The cable-forming machine gearbox is used helical bevel gear, comprises the gear mass of taper, and gear mass one end face is a small end; The other end is big end, and described gear mass center has mounting hole, is provided with keyway in the mounting hole; It is characterized in that: be evenly distributed with 33 gear teeth on the conical surface of described gear mass; Gear teeth screw is left-handed, and modulus is 6, and helix angle is 20 °; The end face angle of the flank of tooth that the peak of the conical surface or the gear teeth constitutes and the small end of gear mass is controlled between 42 ° ~ 46 °, and face width of tooth is at 35 ~ 45mm.
Described cable-forming machine gearbox is used helical bevel gear, it is characterized in that: the described gear teeth adopt Gleason curved tooth structure.
The cable-forming machine gearbox is used helical bevel gear, it is characterized in that: preferred 44 ° ~ 45 ° of the end face angle of the flank of tooth that the peak of the described gear teeth constitutes and the small end of gear mass.
Described cable-forming machine gearbox is used helical bevel gear, it is characterized in that: preferred 44 ° 59 of the end face angle of the flank of tooth that the peak of the described gear teeth constitutes and the small end of gear mass '.
The utility model has the advantages that:
The utility model reasonable in design; Through design again to gear, the angle of the number of teeth of control gear, modulus, helix angle, the conical surface and end face, the flank profil of gear can fracture rate, twisting coefficient, collapse the tooth rate and reduce greatly; Effectively raise the practicability of gear, prolonged working life.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is A-A schematic representation of Fig. 1.
Embodiment:
Referring to Fig. 1:
The cable-forming machine gearbox is used helical bevel gear, comprises the gear mass 1 of taper, and gear mass 1 one end faces are small end 2; The other end is big end 3, and gear mass 1 center has mounting hole 4, is provided with keyway 5 in the mounting hole 4; Be evenly distributed with 33 gear teeth 6 on the conical surface of gear mass 1, the gear teeth 6 screws are left-handed, and modulus is 6; Helix angle is 20 °, and the end face angle of the flank of tooth 7 that the peak of the conical surface or the gear teeth 6 constitutes and the small end 2 of gear mass 1 is controlled between 42 ° ~ 46 °, and the flank of tooth 7 width are at 35 ~ 45mm.
The gear teeth 6 adopt Gleason curved tooth structure.
The flank of tooth 7 that the peak of the gear teeth 6 constitutes and preferred 44 ° ~ 45 ° of the end face angle of the small end 2 of gear mass 1.
The flank of tooth 7 that the peak of the gear teeth 6 constitutes and preferred 44 ° 59 of the end face angle of the small end 2 of gear mass 1 '.
The utility model is changed system into Gleason curved tooth structural type with the original-pack straight bevel gear gear that manufactures and designs.The Gleason curved tooth is also referred to as the trochoid spiral gear.Under the technical performance that does not change the original transmission speed ratio of equipment; Gear parameter design as follows, tooth number Z=33, modulus m=6, tooth portion helixangle=20 °, the two pairs of gear engagement central angles and φ=90 °, the material of gear is alloyed steel 25MnTiB.Tooth portion heat-treats by technological requirement.Above technical reform scheme has obtained desirable effect in actual use through after implementing.This equipment old trouble do not occurring.Facts have proved that technological transformation project obtains completes success.
