Abstract
The utility model relates to a transmission structure for a hand-held electric threading machine, in particular to the transmission structure for the hand-held electric threading machine used for repairing and processing an external thread of a pipe. The transmission structure for the hand-held electric threading machine comprises a main shell and a reduction gear and is characterized by further comprising a face gear and a gear shaft, wherein the face gear is mounted in the main shell; the gear shaft is mounted in the main shell; a first gear and a second gear are arranged on the gear shaft; the first gear is meshed with the face gear; the second gear is meshed with the reduction gear; the central axis of the gear shaft and the central axis of the face gear are crossed at a 90-degree angle; the first gear is an involute cylindrical gear. The error caused by the axial movement of the gear shaft of the transmission structure for the hand-held electric threading machine almost has no influence on the transmission property; compared with the common cone gear transmission, the face gear transmission has higher contact ratio, and is free from axial force; the face gear transmission theoretically can ensure the transmission at fixed transmission ratio.
Description
Technical field
The utility model relates to a kind of drive mechanism of hand held, electric die head threading machine, relates in particular to a kind of for keeping in repair and process the drive mechanism of the externally threaded hand held, electric die head threading machine of pipe fitting.
Background technology
The hand held, electric die head threading machine of prior art adopts common Bevel Gear Drive, and common Bevel Gear Drive has following shortcoming: the vertex of a cone of two bevel gears will overlap, and axial error will cause serious unbalance loading; Registration is little, and transmission is not steady; Can not guarantee stable gearratio, vibrations are large, and noise is high.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and the drive mechanism of the hand held, electric die head threading machine of a kind of reasonable in design, steady operation is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of drive mechanism of hand held, electric die head threading machine, comprises main casing, reduction gearing; It is characterized in that: also comprise face gear and tooth axle; Face gear is arranged in main casing; Tooth axle is arranged in main casing, on tooth axle, be provided with the first gear and and the second gear, the engagement of the first gear and face gear, the second gear meshes with reduction gearing, the axis of the axis of tooth axle and face gear is in 90 ° crossing; The first described gear is involute cylindrical gear.
The utility model also comprises lining, and face gear is arranged on main casing by lining.
The utility model compared with prior art, has the following advantages and effect: tooth axle moves axially the error of generation to almost not impact of transmission performance; The transmission of the common cone tooth of face gear ratio has larger registration, and without responsive to axial force; Face gear drive can guarantee stable drive ratio transmission in theory.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1, the utility model embodiment comprises gland 1, face gear 2, lining 3, main casing 4, tooth axle 5, bearing 6, reduction gearing.
Face gear 2 is rotatably installed on main casing 4 by lining 3, and lining 3 opposite gears 2 are spacing at axial direction.End face at face gear 2 is provided with tooth.Face gear 2 is connected with the mantle fiber mechanism of die head threading machine.
Tooth axle 5 is rotatably installed on main casing 4 by bearing 6.On tooth axle 5, be provided with the first gear 7 and the second gear 8, the first gears 7 and the second gear 8 one-body molded on tooth axle 5, the first gear 7 axis, the second gear 8 axis, tooth axle 5 axis are with point-blank.The first gear 7 and 2 engagements of face gear, the flute profile on the first gear 7 and the flute profile of face gear 2 are supporting.The second gear 8 and reduction gearing engagement.In 90 ° the intersecting of axis of the axis of tooth axle 5 and face gear 2, the first gear 7 is involute cylindrical gear, and the error that tooth axle 5 moves axially generation is like this on almost not impact of transmission performance.
After motor power slows down by reduction gearing, by 5 outputs of tooth axle, tooth axle 5 drives face gear 2 to rotate, and face gear 2 drives mantle fiber mechanism to rotate, and realizes 2 transmissions of face gear.
In addition, it should be noted that, the specific embodiment described in this description, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this description is only to the explanation of the utility model structure example.
