Abstract
The utility model discloses a speed reduction box comprising a box body and a driving wheel, wherein one side end surface of the driving wheel is fixedly connected with a driving shaft and the driving wheel is rotatably connected inside the box body by the driving shaft; the box body is provided with a box body cover plate for sealing the driving wheel inside the box body; and the box body cover plate is provided with a support structure for supporting the driving wheel. For the support structure, a through hole is preferable and used for bearing the stress at one side of the driving wheel near a box body end cover; the through hole can play a role similar to a sliding bearing; one side connected with the driving wheel is stressed radially; the radial stress at two end surface side parts of the driving wheel are ensured to balance and the external factor of radial runout of the driving shaft part inside the speed reduction box as well as the driving wheel supported by the driving shaft is effectively eliminated; and simultaneously the working efficiency and the driving accuracy of the speed reduction box are improved.
Description
Technical field
The utility model relates to a kind of speed reducer.
Background technique
Speed reducer is as a kind of intermediary transmission device, and mostly inner transmission system is that gear cooperates composition with axle.The speed reducer that some are small-sized, inner transmission system is comparatively simple, have or have only the two-stage transmission, i.e. mover input driving torque is to speed reducer, speed reducer is done a speed regulation, then outputs to terminal equipment.The simple transmission process of this type, internal structure is also mostly fairly simple, and the speed reducer transmission shaft had often both been born transmission agency, the negative supporting effect to the drive wheel in the speed reducer of holding concurrently again.But so simple drive mechanism has its drawback equally; Because having only transmission shaft that the speed reducer inner driving wheel is made monolateral axle supports; After speed reducer when work or work a period of time, cause speed reducer intermediate solid drive shaft part easily and the circular runout of the drive wheel that supported.
The model utility content
The technical problem that the present invention will solve provides a kind of speed reducer, and the speed reducer internal structure after the improvement can effectively solve the speed reducer inner driving wheel and transmission shaft partly is prone to produce the problem of circular runout.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is; A kind of speed reducer comprises casing and drive wheel, a side end face of drive wheel and transmission shaft is affixed and drive wheel through transmission shaft switching in casing; Casing is provided with drive wheel is enclosed in the box cover in the casing; Said box cover is provided with the supporting structure that supports drive wheel, and said supporting structure is used to carry the stressed of non-outbound course one side of drive wheel, can effectively solve the issuable circular runout problem of the monolateral support of drive wheel.
As a kind of improvement, said supporting structure is the through hole that is located on the box cover, on through hole and the drive wheel near the wheel hub step corresponding matching on box cover one side end face, for drive wheel provides a strong point near box cover one side.
As a kind of improvement; Said wheel hub step comprises the first ladder section that is located on the drive wheel end face and is located at the second ladder section on the first ladder section and is located at the 3rd ladder section on the second ladder section that the said second ladder section cooperates with through hole and the second ladder section and drive wheel concentric.
As a kind of improvement; The annular end face of the first ladder section and box cover inner side surface are fitted; Guarantee that the casing end face only needs contact with the drive wheel multidiameter shaft second ladder section annular end face small size, reduced generation when drive wheel turns round and box cover between frictional force.
As a kind of improvement, the diameter of the said first ladder section is greater than the diameter of the second ladder section, and the diameter of the second ladder section is greater than the diameter of the 3rd ladder section.
On the speed reducer box cover, establish through hole; What can guarantee drive wheel all has the strong point with the affixed end face side of transmission shaft with near the end face side of box cover; Said like this through hole can play the effect of a similar sliding bearing; Carry the radial force of a side of drive wheel; Guarantee drive wheel and two end face side sections radial force balances, the external factor of the circular runout of transmission shaft part in the speed reducer of effectively having forgone and the drive wheel that is supported thereof has improved the transmission efficiency and the transmission accuracy of speed reducer simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
Embodiment
A kind of embodiment's of the utility model as shown in Figure 1 structural representation, a kind of speed reducer comprises casing and drive wheel 1; One side end face of drive wheel and transmission shaft is affixed and drive wheel through transmission shaft switching in casing, casing is provided with drive wheel is enclosed in the box cover 6 in the casing, said box cover 6 is provided with the supporting structure that supports drive wheel 1; In the utility model; Said supporting structure is the through hole 7 that is located on the box cover, and through hole and drive wheel are near the wheel hub step corresponding matching on box cover one side end face, like this; Can guarantee drive wheel both sides stress balance for drive wheel provides a strong point near box cover one side.Said wheel hub step comprises the first ladder section 2 that is located on the drive wheel end face and is located at the second ladder section 3 on the first ladder section and is located at the 3rd ladder section 4 on the second ladder section 3; The said second ladder section 3 cooperates with through hole 7 and the second ladder section and drive wheel concentric; Radial force is even when guaranteeing the drive wheel rotation, stressed be the centrifugal force that size is identical all the time.The annular end face of the first ladder section and box cover inner side surface are fitted, the frictional force between that little fitting area forms in the time of can reducing the drive wheel rotation and the box cover.The diameter of the first ladder section 2 is greater than the diameter of the second ladder section 3, and the diameter of the second ladder section is greater than the diameter of the 3rd ladder section, and it is comparatively convenient by the descending order manufacturing of diameter from inside to outside to be designed to the wheel hub step like this.
Except that above-mentioned preferred embodiment; The utility model also has other mode of execution; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
