Description

Shaft

Technical field

The utility model is related to a kind of Axle Parts more particularly to a kind of shafts.

Background technology

When present axis installs gear, gear is installed on the both ends on axis with nut and passes through gear installation end face and fixation Disk is fixed, this mounting means, can such as use screw thread glue fixing nut there is a phenomenon where nut loosening after prolonged use It makes troubles to later maintenance position, it has not been convenient to dismount, nut is tightened Ru general, then because of shaft long-time rotary work state Make nut loosening, the clamping face at gear both ends that cannot be clamped well and generate sliding, influences shaft normal use.

In the prior art, such as Patent No.：CN206257250, patent name are rotary shaft, are set on the left of fixed disk There is washer, which is the tight fit solved between gear and fixed disk, and it is tight with gear face not solve gear The problem of cooperation, i.e., after nut is tightened, which still can generate sliding because long-time rotates so that end face occurs between the two Gouging abrasion reduces the service life.

Therefore, it is necessary to provide a kind of new above technical problem of shaft solution.

Utility model content

The utility model, which provides, a kind of can preferably be clamped gear both ends, not by the shaft of long-time Effect of Rotation.

The purpose of this utility model is to provide a kind of shafts, including axis, the gear of setting on the shaft to install end face, It is cased with axle sleeve on gear installation end right side of face axis, is arranged with the first washer, second packing ring and fixed disk on axle sleeve respectively, it is described First washer closes on gear installation end face, and the second packing ring and fixed disk are fixed in the sleeve end by nut On gear installation end right side of face axis, the two sides of first washer are equipped with cricoid burr.

Preferably, the diameter of first washer is equal to gear installation end face outside diameter.

Preferably, the burr single side face at least two, circumferentially transmitting distribution.

Preferably, the section of the burr is triangle or trapezoidal.

Preferably, first washer and second packing ring are rubber parts.

Preferably, the fixed disk welds together with axle sleeve, and the second packing ring is pasted on the left side of fixed disk.

Preferably, it also is provided with burr on side of the second packing ring far from fixed disk.

Preferably, the burr of the second packing ring closes on axle sleeve setting.

Preferably, the axle sleeve and axis are key connection, and the axial position of axle sleeve outer end face is equipped with keyway.

Compared with the relevant technologies, shaft provided by the utility model has following beneficial aspects：

One, the right side that end face is installed in gear is equipped with the first washer, and burr is equipped on the first washer, and the structure is in spiral shell It is preferably bonded when mother is tightened and is installed between end face and face of gear in gear, form tight fit, do not generate for a long time using hair Raw loosening preferably avoids the abrasion that sliding generates；

Two, it also is provided with burr in second packing ring, ensure that gear right side and fixes the tight fit of disk, simple in structure, Effectively extend the service life of shaft.

Description of the drawings

Fig. 1 is the structural schematic diagram of shaft provided by the utility model；

Fig. 2 is the structural schematic diagram of the first washer in Fig. 1.

Specific implementation mode

The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting In the case of, the feature in the embodiments of the present invention and embodiment can be combined with each other.For sake of convenience, hereinafter such as There are "upper", "lower", "left", "right" printed words, only indicates consistent with the upper and lower, left and right direction of attached drawing itself, not to structure Play restriction effect.

Please refer to Fig. 1 and Fig. 2, wherein Fig. 1 is the structural schematic diagram of shaft provided by the utility model, and Fig. 2 is figure The structural schematic diagram of the first washer in 1.The gear installation end face 2 that the shaft includes axis 1, is arranged on the axis 1, in tooth It is cased with axle sleeve 3 in wheel installation 2 right-hand axis of end face.The first washer 4, second packing ring 5 and fixed disk 6 are arranged on axle sleeve 3 respectively.Institute It states the first washer 4 and closes on gear installation end face, the diameter of first washer 4 is equal to gear and installs end face outside diameter, Its two sides is equipped with cricoid burr 8, and one side abuts gear and installs end face 2, and another side abuts a left side for gear to be installed Side.The section of the burr 8 is triangle or trapezoidal.The burr 8 is at least two in single side face, circumferentially transmitting point Cloth.

The second packing ring 5 and fixed disk 6 are fixed on gear by nut 7 in 3 end of the axle sleeve and install 2 right side of end face On axis, the fixed disk 6 welds together with axle sleeve 3, and the second packing ring 5 is pasted on the left side of fixed disk 6.The axle sleeve 3 with axis 1 be key connection, and the axial position of 3 outer end face of axle sleeve is equipped with keyway, and the keyway is for installing gear.Keyway is installed as existing There is technology, so the utility model is not shown.

The second packing ring 5 also is provided with burr on the side far from fixed disk 6, which closes on the setting of axle sleeve 3, abuts tooth The right side of wheel.First washer and second packing ring are that rubber material is made.

Burr diameter in the second packing ring 5 is more than the diameter of the first washer 4, and the two staggeredly abuts face of gear, folder It holds more firm.

The fixed disk 6 welds together with axle sleeve 3, and the second packing ring 5 is pasted on the left side of fixed disk 6.Pacifying When cogged, lower nut 7, fixed disk 6 and axle sleeve 3 are unloaded successively.Gear is mounted on axle sleeve 3 and is fixed with key, then axle sleeve 3 is answered On axis 1, gear one side abuts the first washer 4, loads onto the fixation disk 6 with second packing ring 5, tightens nut 7 for position.

When tightening nut 7, the triangle of burr 8 or it is trapezoidal compressed, again because rubber material expandable flexibility In the case of characteristic, the tight fit between gear and washer, gear installation end face is realized, contact friction force is increased, by This is realized gear is fixed on two washers between, not when running to for a long time sliding, generates the phenomenon that wearing due to loosen, Extend the service life of shaft.

Gear is fixed on axis indirectly, is not easy to cause to damage to axis, is avoided the problem of drawing gear and is brought showing for ring continent As occurring, reduce maintenance cost.

The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other relevant technical fields, are equally included in the patent within the scope of the utility model.
