Abstract
The utility model provides a butt assembling gear structure which relates to a wheel body or a rim assembled with knock-down component. The utility model mainly aims at resolving the technical problems such as convenient maintenance, and the corresponding technical proposal of the utility model is that: the gear is formed by enchasing a symmetrical left semi-circle gear and a right semi-circle gear; the center of the left semi-circle gear and the right semi-circle gear is provided with a symmetrical semi-fixed hole; the left semi-circle gear and the right semi-circle gear are mutually enchased to form a full fixed hold which can pull a driving axle, thereby forming a butt assembling gear structure which is suitable for all driving device.
Description
Technical field:
The utility model relates to a kind of toothed element with translatory movement, particularly a kind of wheel body or wheel rim of being dressed up by loose parts that have.
Background technique:
Known conveyor gear mostly as shown in Figures 1 and 2, the gear 1 that its structure is formed in one, this gear 1 central fixed hole 11 can place a transmission shaft 12, and by 1 rotation of motor drives gear, and then conveyor belt 13 is advanced, yet this gear 1 is desired to pull down when changing, must earlier locking transmission shaft 12 two ends lock tubes 14 be pulled down, subsequently transmission shaft 12 is extracted out, again gear 1 is pulled down replacing from transmission shaft 12, after also in regular turn gear 1 being sheathed on transmission shaft 12 when installing gear 1 relatively, utilize lock tube 14 that transmission shaft 12 two ends are locked on the conveyor again; This shows that the known gear maintenance dismounting step that is used for conveyor is complicated and do not have a convenience.
Right this known conveyor belt is not difficult to summarize disappearance as described below in actual user mode degree:
Promptly, known gear is desired to pull down when changing, must earlier the lock tube at locking transmission shaft two ends be pulled down, subsequently transmission shaft is extracted out, again gear is pulled down replacing from transmission shaft, also in regular turn geared sleeve is located at transmission shaft when installing gear relatively after, utilize lock tube that the transmission shaft two ends are locked on the conveyor again, this shows that the known gear maintenance dismounting step that is used for conveyor is quite complicated and do not have a convenience.
Summary of the invention:
The technical problems to be solved in the utility model is, provides a kind of improved to dress built-up gear structure, it can be fast gear changing more, maintenance is quite convenient.
The technological scheme that solves the problems of the technologies described above employing is, gear is to be rabbeted mutually by two symmetrical mutually left and right semi-circle gears to constitute, this left and right semi-circle gear centre respectively is formed with symmetrical semifixed hole, and left and right semi-circle gear is rabbeted mutually and become a complete fixed hole that can place transmission shaft.
The composite structure of the left and right semi-circle gear of the utility model mat when gear maintenance dismounting, only needs left and right semi-circle gear is separated and can pull down replacing from transmission shaft, does not need to dismantle any member of transmission device again, and maintenance is quite convenient.
Description of drawings:
Fig. 1 is known gear schematic representation.
Fig. 2 is known gear assembling schematic representation.
Fig. 3 is the utility model embodiment schematic representation.
Fig. 4 is the utility model left semicircle gear structure schematic representation.
Fig. 5 is the utility model transmission shaft structure schematic representation.
Fig. 6 is the utility model right semi-circle gear structure schematic representation.
Embodiment:
Shown in Fig. 3 and cooperation and Fig. 4,5,6, it is respectively embodiment's schematic representation of the present utility model and implements the assembling schematic representation.
As seen from the figure, described in the utility model mainly is by two symmetrical mutually left sides to dress built-up gear structure 2, right semi-circle gear 21,22 mutual interlockings form a gear 2, this left side, right semi-circle gear 21,22 centre respectively are formed with symmetrical semifixed hole 211,221, it is can be by a left side, right semi-circle gear 21,22 mutual interlocking and become a complete fixed hole and use and place a transmission shaft 3, and this fixed hole 211, the 221st, can be designed to the aspect of multiple difference according to the shape of transmission shaft 3, as: square, circular, polygonal or other similar geometric etc.; The semifixed hole 211 of aforementioned left semicircle gear 21 or right semi-circle gear 22 or 221 can be formed with engagement groove 23 up and down, its can with the semifixed hole 221 of right semi-circle gear 22 or semi-circle gear 21 or the 211 clamping block 24 mutual driving fits that formed up and down, aforementioned engagement groove 23 upper and lower surfaces respectively are provided with a latch 231, it can be inserted in the hinge last 241 of clamping block 24, and then finishes the chimeric to form a complete gear 2 of left and right semi-circle gear 21,22;
Claims (5)
1, a kind of to dress built-up gear structure, it is characterized in that: gear is to be rabbeted mutually by two symmetrical mutually left and right semi-circle gears to constitute, this left and right semi-circle gear centre respectively is formed with symmetrical semifixed hole, and left and right semi-circle gear is rabbeted mutually and become a complete fixed hole that can place a transmission shaft.
2, according to claim 1 to dress built-up gear structure, it is characterized in that this fixed hole is square, circle or the polygonal that can be designed to the aspect of multiple difference according to the shape of transmission shaft.
3, according to claim 1 to dress built-up gear structure, the semifixed hole that it is characterized in that this left semicircle gear or right semi-circle gear up and down can be formed with engagement groove, its can with the semifixed hole mutual driving fit of formed clamping block up and down of right semi-circle gear or left semicircle gear.
4, according to claim 3 to dress built-up gear structure, it is characterized in that this engagement groove upper and lower surface can respectively be provided with a latch.
5, according to claim 3 to dress built-up gear structure, it is characterized in that this clamping block can be provided with the hinge last of the latch of plant engagement groove.
