Abstract
The invention discloses a bevel gear. The bevel gear is characterized in that the bevel gear comprises a gear tooth part (1), a gear shaft part (2) and a screw part (3); the gear tooth part (1), the gear shaft part (2) and the screw part (3) are sequentially connected and integrally designed; at least six locking pin holes (4) are evenly formed in the outer wall of the screw part (3) in the circumferential direction; the locking pin holes (4) are all perpendicular to the axis of the screw part (3), and every two locking pins holes (4) are communicated with each other. The bevel gear has the beneficial effects that the gear can be firmly installed; the situation that the gear is prone to looseness in the transmission process due to a long service cycle of the gear is avoided, so that the transmission process is more stable, the mechanical efficiency is improved, and the safety performance of equipment is improved.
Description
Technical field
The present invention relates to gear technique field, specifically, is a kind of umbrella gear.
Background technique
The structural type of gear is varied, of a great variety, can classify according to its profile, tooth trace shape, surface, gear teeth place, manufacture method etc., is divided into cylindrical gears, wheel teeth portion, noncircular gear, tooth bar, worm and worm gear etc. by its profile; Spur gear, helical gear, herringbone gear, bevel gear, curved tooth cylindrical gear etc. are divided into by tooth trace shape.Gear, as a kind of common power transmission mode, is widely used in the every field in production, life.
Wherein, driving bevel gear is in installation connects, and do not lock pin-and-hole very little or directly owing to screw rod being locked pin-and-hole, easily cause screw rod to connect unstable situation, in transmission process, because gear constantly rotates, loosening easily appears in screw rod, makes fluctuation of service.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of umbrella gear, by being provided with multiple locking pin-and-hole in screw part, can Small-angle Rotation gear when making installation, make installation more firm, overcome the situation about loosening that driving gear occurs in transmission process, improve mechanical efficiency, make transmission process more stable.
For achieving the above object, the concrete technological scheme that the present invention adopts is as follows:
A kind of umbrella gear, comprise wheel teeth portion, wheel shaft portion and screw part, described teeth portion, wheel shaft portion and the screw part of taking turns is connected and integral design in turn, described screw part outer wall is circumferentially evenly provided with at least 6 locking pin-and-holes, each described locking pin-and-hole all perpendicular to the shaft axis of screw part, and communicates between two.
By above-mentioned design, when gear is installed, by screw part, gear is fixed, but because equipment is heavy, gear still exists loosening, then by locking pin-and-hole, is locked further by gear, and arrange more owing to locking pin-and-hole, during installation more for convenience, and effective, can comparatively gear fixation, avoid in transmission process situation gear easily occurring and loosens, improve Safety performance.
Further describe, fix for the ease of mounting box, described locking pin-and-hole is near the end of described screw part.
Further describe again, described wheel shaft portion is provided with spline.
Further describe, use for the ease of people, locking pin-and-hole is unsuitable excessive, and described locking pin-and-hole aperture is 5 ~ 7mm.
Beneficial effect of the present invention is: by being provided with multiple locking pin-and-hole in screw part, can gear be installed more firm, and overcome the situation occurring in transmission process because gear life cycle is long loosening, make transmission process more stable, improve the Safety performance of mechanical efficiency and equipment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
In figure, 1. take turns teeth portion, 2. wheel shaft portion, 3. screw part, 4. lock pin-and-hole, 5. spline.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention and working principle are described in further detail.
As can be seen from Figure 1, a kind of umbrella gear, comprise wheel teeth portion 1, wheel shaft portion 2 and screw part 3, wheel teeth portion 1, wheel shaft portion 2 are connected and integral design in turn with screw part 3, the outer wall of screw part 3 is circumferentially evenly provided with at least 6 locking pin-and-holes 4, and locking pin-and-hole 4 is all perpendicular to the shaft axis of described screw part 3, and communicate between two;
It can also be seen that from Fig. 1, locking pin-and-hole 4 is near the end of screw part 3; Wheel shaft portion 2 is provided with spline 5.
Preferably, locking pin-and-hole 4 aperture is 5 millimeters to 7 millimeters, and in the present embodiment, aperture is 6 millimeters.
Working principle of the present invention is: gear is connected on transmission shaft by screw part 3, pass through swing pinion, gear is slowly rotated along the screw thread in screw part 3, gear is installed fixing, when gear rotate to can not readvance time, staff utilizes pin and inserts locking pin-and-hole 4, further gear is rotated, gear is connected firmly, simultaneously when dismantling, also by identical method, Small-angle Rotation can be carried out to gear.
Claims (4)
