Abstract
The utility model discloses a worm speed reducer with an engaging and disengaging function, which comprises an output shaft, a spring, a connecting key, a worm gear and an adjusting bolt, wherein the spring is mounted into a spring hole of the output shaft; the connecting key is inserted into a radial key slot of the output shaft; one end of the spring is in contact with the bottom of the spring hole of the output shaft; the other end of the spring is in contact with the connecting key; the adjusting bolt is in screw connection with the spring hole; and the worm gear is arranged on the output shaft in a sleeving manner, and is in clearance fit with the output shaft. The worm gear can be engaged or disengaged with the output shaft by adjusting the adjusting bolt, so that the output shaft operates or does not operate along with the worm gear. The worm speed reducer has the benefits that (1), when the worm speed reducer is used in special environments, the output shaft can rotate independently; (2), connected components can be rotated by hands; and (3), the structure is simple and compact, and the mounting and the use are convenient.
Description
Technical field
The utility model relates to a kind of worm reduction gear, particularly a kind of worm reduction gear with the clutch function.
Background technique
Speed reducer utilizes the speed discrepancy of gear as a kind of power transmitting mechanism, and the winding number of motor is decelerated to desired winding number, and to larger output torque.The conversion equipment that is widely used in speed and moment of torsion is such as boats and ships, automobile, locomotive, machining machine and tool and automated production equipment, household electrical appliances and clock and watch etc.And worm-gear speed reducer is owing to have the reverse self-locking function, larger reduction speed ratio can be arranged, input shaft and output shaft be not on same axis, also not at grade, the characteristics such as cost is low, so requiring to have auto-lock function, be widely used in the speed of high reduction speed ratio and the torque axis exchange device.The output shaft of existing worm reduction gear all is that key is fixedly connected with worm gear, do not possess clutch function, cause if in the situation of power input device running, the power reception unit is stopped, then need clutch mechanism is installed in addition loaded down with trivial details when causing output power device and power reception unit to link together, effort, the problem that structure is not compact.When some particular surroundingss were used, output shaft can not rotate separately equally, and can not carry out the parts that manual rotation connects.
Summary of the invention
In order to overcome above-mentioned shortcoming and defect, the utility model provides a kind of worm reduction gear with the clutch function, the output shaft of this worm reduction gear can separate rotation with worm gear, can satisfy output shaft and rotate separately, and can carry out the usage requirement of the parts of manual rotation connection.
The utility model is that the technological scheme that the technical problem of the above-mentioned proposition of solution adopts is: a kind of worm reduction gear with the clutch function, include output shaft, spring, connecting key, worm gear, adjusting bolt, it is characterized in that, described spring is packed in the spring eye of output shaft, radially connecting key is inserted in the redial key slotted eye of output shaft again, one end of spring contacts with at the bottom of the spring eye of output shaft, the other end of spring contacts with connecting key, adjusting bolt is connected with the spring eye spiral, worm gear is inserted on the output shaft, and worm gear and output shaft are Spielpassung.
Further, a kind of worm reduction gear with the clutch function of the utility model also comprises following technical characteristics:
Have spring eye on the central axis of described output shaft, the aperture of spring eye has one section internal thread.
Described output shaft radially has a redial key slotted eye.
Radially have a dowel hole on the described worm gear.
Described adjusting bolt can be moved at the spring eye internal spiral.
The beneficial effects of the utility model are: when used in some particular surroundingss (1), output shaft can rotate separately; (2) can carry out the parts that manual rotation connects; (3) simple in structure, compact, conveniently install and use; (4) solve existing speed reducer and do not possessed clutch function, cause if in the situation of power input device running, the power reception unit is stopped, then need clutch mechanism is installed in addition loaded down with trivial details when causing output power device and power reception unit to link together, effort, the problem that structure is not compact.
Description of drawings
Fig. 1 is that structure master of the present utility model looks schematic representation.
Fig. 2 is that the C of worm gear is to schematic representation.
Among the figure, 1 is that output shaft, 2 is that spring, 3 is that spring eye, 4 is that redial key slotted eye, 5 is that connecting key, 6 is that worm gear, 7 is that adjusting bolt, 8 is dowel hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
A kind of worm reduction gear with the clutch function, include output shaft 1, spring 2, connecting key 5, worm gear 6, adjusting bolt 7, it is characterized in that, described spring 2 is packed in the spring eye 3 of output shaft 1, radially connecting key 5 is inserted in the redial key slotted eye 4 of output shaft 1 again, one end of spring 2 contacted with 3 ends of spring eye of output shaft 1, the other end of spring 2 contacts with connecting key 5, adjusting bolt 7 is connected with spring eye 3 spirals, worm gear 6 is inserted on the output shaft 1, worm gear 6 is Spielpassung with output shaft 1, have spring eye 3 on the central axis of described output shaft 1, the aperture of spring eye 3 has one section internal thread, and output shaft 1 radially has a redial key slotted eye 4, radially have a dowel hole 8 on the described worm gear 6, described adjusting bolt 7 can be moved at spring eye 3 internal spirals.Like this, the certain position of adjusting bolt 7 rotation direction B end, spring 2 is pushed connecting key 5 direction of worm gear 6 to, snaps in the worm gear dowel hole 8, and this moment, worm gear 6 drive output shafts 1 together rotated.The certain position of adjusting bolt 7 rotation direction A end, adjusting bolt 7 is pushed connecting key 5 opposite direction of worm gear 6 to, and connecting key 5 breaks away from worm gear dowel holes 8, this moment worm gear 6 with output shaft 1 disengagement, output shaft 1 is free to rotate.
Above disclosed only is preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the utility model and contains.
