Description
Technical field
The utility model relates to the automatic switch of a kind of automatic water, gas, valve class and the draw-gear in control field, particularly a kind of tractor simple in structure, stay-in-grade.
Background technology
Tractor in the market probably has two kinds, a kind of structure, and gear housing is by last; Lower house is formed, and casing is built-in with a center fixation frame, the below of center fixation frame; A synchronous machine promptly is housed in lower house, is fixing the axle that supplies gear operation on the pole plate of synchronous machine, adorning one group of gear assembly that increases moment through slack-off speed on the axle; Also vertical on the pad-face of synchronous machine an electromagnet assembly is housed, energising back synchronous machine is worked with electromagnet simultaneously, and the synchronous machine driven gear turns round; Electromagnet adhesive, electromagnet adhesive produce leverage and make a braking of end bumping post damping block gear, because of the engagement of the internal gear in braking damping block gear and the asteroid change-speed gearing assembly; So this internal gear is prevented after the rotation, the rotation of synchronous machine could then drive whole gear assembly running, and the power output of generation is delivered to the top of center fixation frame through output gear shaft by output gear; Make fixedly middle cover and the interior tooth bar that connects with the external member generation translation traction that is provided with of upper shell, the stroke of traction and distance are cam arrival appointed positions that plays on-off action that is driven by output gear; Cam unclamps the decision of contact switch formula copper spring sheet, and traction finishes the independent outage of rear motor and quits work, and electromagnet continues to keep adhesive; Make the function of generation continue to keep; When the turnaround time that the device arrival of control traction motor is set, whole traction motor outage, electromagnet produces answer by the extension spring effect of itself; No longer control the internal gear in the asteroid change-speed gearing assembly, at this moment traction motor makes traction motor get back to original initial state owing to receive the return force effect that is pulled thing.
The deficiency that the traction motor of this structure exists is: 1 complicated integral structure; The action meeting that 2 electromagnet assemblies are produced the incessantly enough sliding phenomenons of going back of tractive effort midway occur owing to the accumulative total foozle of tractor itself is braked incessantly damping block; 3) the planetary gear set complex structure in the change-speed gearing assembly, part is more, for the difficult control of quality; 4 costs of raw material are high, and manufacturing cost is high.
Another kind is applied to the traction motor of single container washing and extracting machine, and the control principle of electromagnet is changed into a magnet ring, produces the principle of cutting magnetic field through magnet ring; Drive a gear that is embedded with copper band or aluminium circle, drive the gear that one group of speed change increases moment again by the gear that is embedded with copper band or aluminium circle then, make the gear of one of them buckle; Catch on braking damping block gear, the internal gear in the braking damping block gear braking driving gear component is worked by a part that is similar to driving lever after traction puts in place; Let running part separate the transmission of motor; Motor continues to drive magnet ring rotation cutting magnetic field, makes the gear assembly braking damping block gear that is embedded with copper band, and internal gear keeps on-position always; Function after tractor is put in place continues to keep; After the device of control tractor arrives the time of setting answer, the traction motor outage, this moment, magnet ring and copper band made its return through an extension spring; No longer brake damping block and internal gear, traction motor is got back to original initial state by the return force effect that is pulled thing.
The shortcoming of this kind tractor is a complex structure; Replace magnet ring, copper band, the extension spring of electromagnet part that a proportion relation that is difficult to the power of control is arranged; And quality is extremely unstable; Because manufacture difficulty is high, has increased the cost of human cost and equipment aspect, so equally also be the cost that has increased product.
