Abstract
The utility model provides a worm assembly of a speed reducer, belongs to the technical field of machinery, and solves the problems in the prior art that the worm of the speed reducer is low in transmission efficiency, large in abrasion and troublesome in maintenance. The worm assembly of the speed reducer comprises a worm body meshed with a worm gear and an auxiliary coupling part, wherein a main coupling portion is arranged at one end of the worm body, a shaft hole is arranged on the upper portion of the auxiliary coupling part, and the lower portion of the auxiliary coupling part is meshed with the main coupling portion. The worm assembly of the speed reducer has the advantages of being high in transmission efficiency, small in abrasion and convenient to maintain.
Description
Technical field
The utility model belongs to field of mechanical technique, has related to a kind of speed reducer, has especially related to a kind of worm component of speed reducer.
Background technique
Worm decelerating machine is a kind of compact structure, and velocity ratio is big, and the gearing that has auto-lock function under certain condition, is one of the most frequently used speed reducer.
Worm decelerating machine comprises casing, worm gear, worm screw, and worm and wheel is located in the casing, and the worm and wheel engagement is provided with bearing between worm screw and the casing, and the bearing place is provided with oil sealing, is used for preventing the oil leakage of bearing.And worm screw is used for being connected with motor, has axis hole at the end of worm screw, and this axis hole can connect and fix with the output shaft of motor.When machine operation, driving worm screw by output shaft rotates, in this process, make the wedging position wearing and tearing of axis hole and output shaft easily, and then output shaft and cooperating of axis hole are fluffed, transmission efficiency descends, and output shaft when cooperating with the axis hole clamping concentricity lower, when transmission, vibrate easily, further increased the wearing and tearing of output shaft and axis hole.In order to keep the efficient that cooperates of axis hole and output shaft, in maintenance, must carry out whole replacing to worm screw, cause maintenance cost higher, produced great waste of material.
Summary of the invention
There are the problems referred to above in the utility model at existing technology, has proposed a kind of worm component of speed reducer, has transmission efficiency height, wearing and tearing advantage little, easy to maintenance.
The utility model is realized by following technical proposal: a kind of worm component of speed reducer, speed reducer comprises casing and is located at casing interior worm gear and worm component, this worm component comprises the body of rod with the worm gear engagement, it is characterized in that, one end of the described body of rod is main shaft coupling portion, this worm component also comprises a secondary coupling piece, and the top of described secondary coupling piece has the axis hole that can fix with motor output shaft, and mesh with described main shaft coupling portion the bottom of described secondary coupling piece.
Output shaft and the axis hole of motor connect and fix, and when machine operation, output shaft drives secondary coupling piece and rotates, and the bottom of secondary coupling piece and the engagement of main shaft coupling portion, thereby the body of rod can rotate the work of the worm gear of body of rod drive afterwards along with the rotation of output shaft.
In the worm component of above-mentioned a kind of speed reducer, described main shaft coupling portion has rectangular teeth, has rectangle groove between two adjacent described rectangular teeths, and the shape of the lower shape of described secondary coupling piece and main shaft coupling portion is complementary.
In the worm component of above-mentioned a kind of speed reducer, described shaft hole inner wall axially is provided with for the groove that fixes with motor output shaft.
Compared with prior art, the worm component of this speed reducer has the following advantages:
1, an end of the body of rod is main shaft coupling portion, and with the engagement of the bottom of secondary coupling piece, the top of secondary coupling piece has axis hole and fixes with motor output shaft, setting can improve the concentricity of motor output shaft and the body of rod like this, reduce the wearing and tearing of motor output shaft and axis hole, improve the transmission efficiency of motor output shaft and worm component.
2, in the time of axis hole and motor output shaft serious wear, can directly change secondary coupling piece, easy to maintenance, maintenance cost is low.
Description of drawings
Fig. 1 is the structural representation of speed reducer.
Fig. 2 is the structural representation of worm component.
Among the figure, 1, the body of rod; 2, main shaft coupling portion; 3, secondary coupling piece; 4, axis hole; 5, groove; 6, rectangular teeth; 7, rectangle groove; 8, bearing; 9, oil sealing; 10, casing; 11, worm gear.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.
As shown in Figure 1, speed reducer comprises casing 10 and is located at worm gear 11 and worm component in the casing 10, and this worm component comprises the body of rod 1 with worm gear 11 engagements, and an end of the described body of rod 1 is main shaft coupling portion 2; This worm component also comprises a secondary coupling piece 3, and the top of described secondary coupling piece 3 has axis hole 4, and axis hole 4 inwalls axially are provided with for the groove 5 that fixes with motor output shaft, and mesh with main shaft coupling portion 2 bottom of secondary coupling piece 3; Main shaft coupling portion 2 is fixed on the casing 10 by bearing 8, and oil sealing 9 is used for stuffing box bearing 8, avoids oil leakage.When machine operation, output shaft inserts axis hole 4 and is fixed by the groove 5 of axis hole 4, drive secondary coupling piece 3 and rotate when output shaft rotates, and the bottom of secondary coupling piece 3 and main shaft coupling portion 2 meshes, thereby the body of rod 1 can rotate the body of rod 1 drive worm gear 11 work afterwards along with the rotation of output shaft.
As shown in Figure 2, main shaft coupling portion 2 has rectangular teeth 6, has rectangle groove 7 between two adjacent rectangular teeths 6, and the shape of the lower shape of secondary coupling piece 3 and main shaft coupling portion 2 is complementary, and setting can make bottom engagement better of main shaft coupling portion 2 and secondary coupling piece 3 like this.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as the body of rod 1, main shaft coupling portion 2, secondary coupling piece 3, axis hole 4, groove 5, rectangular teeth 6, rectangle groove 7, bearing 8, oil sealing 9, casing 10, worm gear 11 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
