Abstract
The utility model discloses a worm gear conversion shaft. The worm gear conversion shaft comprises a shaft body, a damping spring and two electric brush rings mounted at two ends of the shaft body, a wire is arranged in a center hole which is formed in the shaft body, two ends of the wire are connected with the two electric brush rings respectively, the shaft body is provided with a damping section, and the damping spring is mounted on the damping section. The electric brush rings arranged at two ends of the worm gear conversion shaft can be used for circuit connection, so that external wire connection is reduced, and the whole worm gear conversion shaft is more compact in structure.
Description
Technical field
The utility model relates to axle field, specifically relates to a kind of worm gear transaxle.
Background technique
Existing worm gear transaxle rotates when in use, and its annex is disagreed with conducting wire, for connecting the circuit at worm gear transaxle two ends.In order to connect the circuit at two ends, often need wire around a very large circle, be exactly like this seeming of whole product in disorder compact not, in the process of using, there is inconvenience.
Model utility content
(1) technical problem that will solve
The deficiency existing for prior art, the utility model provides a kind of two ends to be provided with brush ring, the worm gear transaxle that can connect as circuit.
(2) technological scheme
For achieving the above object, the utility model provides a kind of worm gear transaxle, comprise axis body, damping spring and be arranged on two brush rings at axis body two ends, in described axis body, be provided with mesopore, in described mesopore, be provided with wire, the two ends of described wire are connected with two brush rings respectively, and described axis body is provided with damping section, and described damping spring is arranged in described damping section.
Further, also comprise the first worm gear installation position, the second worm gear installation position and isolation plug, described the first worm gear installation position, isolation plug, the second worm gear installation position, damping section connect from top to bottom successively.
Further, described damping section is provided with spring fitting position, between described damping spring and described spring fitting position, is interference fit.
Further, the material of described axis body is plastics.
Further, described wire is a copper bar.
(3) beneficial effect
The utility model worm gear transaxle two ends are provided with brush ring, can connect as circuit, reduce external wire and connect, and make the structure of whole product compacter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model worm gear transaxle;
Fig. 2 is the structural representation that the utility model worm gear transaxle removes damping spring;
Fig. 3 is the structural representation of body cross section in the utility model worm gear transaxle axle.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of worm gear transaxle of the present utility model as shown in Figure 1, Figure 2 and Figure 3, comprise axis body 8, damping spring 6 and be arranged on two brush rings 7 at axis body 8 two ends, in described axis body 8, be provided with mesopore 81, in described mesopore 81, be provided with wire 9, the two ends of described wire 9 are connected with two brush rings 7 respectively, described axis body 8 is provided with damping section 4, and described damping spring 6 is arranged in described damping section 4.
While using due to axis body 8, rotate, at the two ends of axis body 8, brush ring 7 is set, just can reach by connecting the brush ring 7 at axis body 8 two ends the effect of conduction so in use.
Wherein, also comprise the first worm gear installation position 1, the second worm gear installation position 3 and isolation plug 2, described the first worm gear installation position 1, isolation plug 2, the second worm gear installation position 3, damping section 4 connect from top to bottom successively.
As optimization, described damping section 4 is provided with spring fitting position 5, between described damping spring 6 and described spring fitting position 5, is interference fit; The material of described axis body 8 is plastics; Described wire 9 is a copper bar.On axis body 8, interference installation damping spring 6 can be subdued energy, reduces the vibrations of axis body 8.
The beneficial effects of the utility model: two ends are provided with brush ring, can connect as circuit, reduce external wire and connect, and make the structure of whole product compacter.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
