Abstract
The invention relates to a start out-of-gear device used for motor experiments. The start out-of-gear device comprises a stat drive end gear in sliding fit with a power input shaft key groove, and a load end gear in interference fit with an output shaft. First wedge-shaped inclined teeth are arranged on the end face of the start drive end gear. Second wedge-shaped inclined teeth corresponding to the first wedge-shaped inclined teeth are arranged on the end face of the load end gear. The direction of the second wedge-shaped inclined teeth is opposite to the direction of the first wedge-shaped inclined teeth. The start drive end gear and the load end gear are meshed with each other through the second wedge-shaped inclined teeth and the first wedge-shaped inclined teeth. The start out-of-gear device has the beneficial effects that when the start out-of-gear device is used for start of large-power, large-load or large-inertia rotation bodies, automatic out-of-gear operation is achieved, the number of the gears is decreased on the condition that the diameter of the gears is not changed, smooth transition is achieved in the self-out-of-gear process, and the mechanical friction strength is reduced.
Description
Technical field
The present invention relates to motor test field, be specifically related to motor experiment and start device out of supply.
Background technique
It is comparatively complicated that existing motor experiment starts apparatus structure out of supply, and need hand assisted time out of supply, auxiliary operation mechanism is a leverage, the number of teeth of starter receiver more than 8 groups, add tooth and the bad control of gear back gaps in man-hour like this, cause force bearing point uneven, increase application risk.
Summary of the invention
In sum, in order to solve existing technical problem, technical problem to be solved by this invention is to provide motor experiment and starts device out of supply.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: motor experiment starts device out of supply, comprise the startup drive end gear that is slidably matched with power input shaft keyway and the load end gear with output shaft interference fit, the end face of described startup drive end gear is provided with the first wedge shape helical teeth, the end face of described load end gear is provided with the second wedge shape helical teeth corresponding with described first wedge shape helical teeth;
The direction of described second wedge shape helical teeth is contrary with the direction of described first wedge shape helical teeth, described startup drive end gear and described load end gear by described second wedge shape helical teeth and described first wedge shape helical teeth mutually meshing.
Further, the axis hole sidewall in the middle part of described startup drive end gear is provided with keyway.
Further, described power input shaft connects high-voltage motor.
The invention has the beneficial effects as follows: automatically out of supply when the solid of rotation for high-power, heavy load or large inertia starts, in the constant situation of gear diameter, decrease the quantity of gear, at smooth excessiveness in out of supply, reduce mechanical friction strength.
Accompanying drawing explanation
Fig. 1 is the structural representation starting drive end gear;
Fig. 2 is the structural representation of load end gear;
Fig. 3 is the meshing schematic diagram starting drive end gear and load end gear.
In accompanying drawing, the list of parts representated by each label is as follows:
1, drive end gear is started, 2, load end gear, the 3, first wedge shape helical teeth, the 4, second wedge shape helical teeth, 5, keyway.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1,2 and 3, motor experiment starts device out of supply, and comprise the startup drive end gear 1 that is slidably matched with power input shaft keyway and the load end gear 2 with output shaft interference fit, described power input shaft connects high-voltage motor.Axis hole sidewall in the middle part of described startup drive end gear 1 is provided with keyway 5.
The end face of described startup drive end gear 1 is provided with the first wedge shape helical teeth 3, the end face of described load end gear 2 is provided with the second wedge shape helical teeth 4 corresponding with described first wedge shape helical teeth 3.The direction of described first wedge shape helical teeth 3 is contrary with the direction of described second wedge shape helical teeth 4, and described startup drive end gear 1 and described load end gear 2 are mutually meshing with described second wedge shape helical teeth 4 by described first wedge shape helical teeth 3.The solid of rotation that the present invention is mainly used in high-power, heavy load or large inertia starts from out of supply.Because the starting power of this type of solid of rotation is comparatively large, the requirement for electrical equipment is relatively high.The axis hole of startup drive end gear 1 and keyway 5 are with input shaft for being slidably matched, and load end helical gear 2 coordinates for being full of with output shaft axle.When solid of rotation initial start stage two gears are engaged each other by the first wedge shape helical teeth 3 and the second wedge shape helical teeth 4, when gear reaches certain rotating speed, load end switches to running and controls major loop, now start end gear 1 reduces speed now to stopping, rotating speed in the process due to start end gear 1 and load end gear 2 is not reciprocity, now the first wedge shape helical teeth 3 at start end gear 1 top slides with load end gear 2 second wedge shape helical teeth 4, take advantage of a situation by start end gear 1 along input shaft to pusher, realize carrying out being separated of start end gear 1 and load end gear 2.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
