Description
Technical field
The utility model relates to cutting out machine technology, specifically a kind of driving cog axle of automatic sharpening tailoring machine helical teeth.
Background technique
The driving cog axle of existing automatic sharpening tailoring machine helical teeth mainly comprises main shaft and helical gear, helical gear is fixed on main shaft by copper bush, copper bush and helical gear synchronous rotary during work, process hardness height was entered on main shaft surface, unavoidably there are wearing and tearing in the rubbed journey of copper bush and main shaft surface, a period of time post gap increases, and causes helical gear coaxality generation deviation, thus noise increases.
Model utility content
The purpose of this utility model is the driving cog axle providing a kind of automatic sharpening tailoring machine helical teeth, one section of bearing fixing part is set in the middle part of main shaft, helical gear is fixed on main shaft by bearing, avoids copper bush easily to occur the problem of wearing and tearing, has feature durable in use, to stablize noise reduction.
For achieving the above object by the following technical solutions:
A kind of driving cog axle of automatic sharpening tailoring machine helical teeth, comprise main shaft and helical gear, it is characterized in that: described main shaft left end arranges connecting thread, the stage casing of main shaft is provided with the bearing fixing part that external diameter reduces from left to right gradually, installation plate washer is set between bearing fixing part and connecting thread, the right side of main shaft is holding part, and holding part arranges jump-ring slot near the position of end, and bearing fixing part and holding part are isolated by spacer groove; Bearing fixing part place is fastened with bearing, and described helical gear is anchored on the periphery of bearing, and the edge of helical gear inner circle is also provided with a circle bulge loop.
The utility model is provided with bearing fixing part in main shaft stage casing, during work, bearing promotes by helical gear active force left, bearing fixing part external diameter reduces setting from left to right gradually, the reliability that can ensure that bearing is fixing is set like this, a circle bulge loop is also provided with at the edge of helical gear inner circle, the lateral engagement of bulge loop and bearing outer rim plays positioning action to helical gear, the stability of guarantee work, holding part on the right side of main shaft is coordinated with machine lock by lining, keep stability during main shaft work, adopting bearing to substitute copper bush can avoid copper bush easily to occur the problem of wearing and tearing, the utility model has durable in use, stablize the feature of noise reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, 2, a kind of driving cog axle of automatic sharpening tailoring machine helical teeth, comprise main shaft 1 and helical gear 2, described main shaft 1 left end arranges connecting thread 11, the stage casing of main shaft 1 is provided with the bearing fixing part 12 that external diameter reduces from left to right gradually, and arrange between bearing fixing part 12 and connecting thread 11 and install plate washer 13, the right side of main shaft 1 is holding part 14, holding part 14 arranges jump-ring slot 15 near the position of end, and bearing fixing part 12 and holding part 14 are isolated by spacer groove 16; Bearing fixing part 12 place is fastened with bearing 3, and described helical gear 2 is anchored on the periphery of bearing 3, and the edge of helical gear 2 inner circle is also provided with a circle bulge loop 21.
The utility model is provided with external diameter and reduces bearing fixing part gradually from left to right in main shaft stage casing, during work, bearing promotes by helical gear active force left, what the such external diameter of bearing fixing part reduced gradually be arranged so that under the promotion of bearing at active force, and fixing reliability is become better and better, a circle bulge loop is also provided with at the edge of helical gear inner circle, the lateral engagement of bulge loop and bearing outer rim, helical gear can be stoped when ring gear contacts with bearing edge to move to side, thus play positioning action, ensure that the stability of the reliability that each parts are fixed and work, holding part on the right side of main shaft is coordinated with machine lock by lining, keep stability during main shaft work, the utility model adopts bearing to substitute copper bush and copper bush can be avoided easily to occur the problem of wearing and tearing, have durable in use, working stability, the feature that noise is low.
