Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Referring to figs. 1 through 5, in the present embodiment, the multi-functional limiter of said no gap gear transmission comprises: base plate assembly 1, and Guan County, gear assembly one 8 upper end is loaded on base plate assembly 1, and the gear of gear assembly 1 and Worm-gear assembly 7 is through 9 coaxial linking to each other of bearing; Gear assembly 2 12.Said gear assembly 1 is the metal gear of surface attachment flexible material with gear assembly 2 12 its gears.Said flexible material comprises: macromolecular material, as: plastics, rubber etc.; Composite material, as: graphite fiber, polyvinyl fiber etc.; Or possesses the other materials of similar performance.
Workflow: multi-functional limiter has comprised the base plate assembly 1 of upper support effect; Gear assembly 1 is coupled connecing on top; The gear of Worm-gear assembly 7 and one 8 coaxial linking to each other of gear assembly; Bearing 1 plays a supportive role to this axle, and double-screw bolt 4, packing ring 1, nut 6 are fastenedly connected the upper and lower surfaces of base plate assembly 1.10 pairs of gear assemblies of spacer 1 carry out the adjustment of mounting point with gear assembly 2 12, and plug 11 plays a part to stop up the gear shaft mounting hole simultaneously, and it is inner to prevent that introduced contaminants from getting into gear-box.Screw 2 15 plays the fixedly effect of wire bushing 13 with packing ring 2 14, and the circuit that reads signal through wire bushing 13 protections is difficult for being damaged.Screw 1 is fixed the upper support element in the base plate assembly 1, and rubber pad 3 is effects of water leakage when loam cake 21 lids are tight.Worm screw 16 can be delivered to the rotational load of outside in the internal gear transmission, finally is delivered on the controller, reads needed semaphore.Packing ring 3 17, back-up ring 18, rubber washer 19, screw 20, packing ring 4 24 are fixed together the loam cake 21 of multi-functional limiter with substructure housing 22 closely.Carry out the connection of circuit through cable joining 23.Bearing 2 25, bearing 3 27, fixed cover 26 cooperate gear assembly 1 with installation through base plate assembly 1 with housing 22 with gear assembly 2 12, play a supporting role.Multi-functional limiter need carry out integral installation after assembling with worm screw 16 and bearing 2 25, fixed cover 26 in installation process.Because driving gear adopts soft material to carry out surface attachment, makes that the gap between the gear does not exist in theory, therefore when the forward and reverse rotation of size, can not produce error and testing precision is caused very big influence.
Brief summary: The present invention be directed to a kind of multi-functional limiter and use; The applied multi-functional limiter of the present invention is a kind of being installed on the tower crane hoisting mechanism, detects the rope stretching amount of elevator and reaches the feeler mechanism of real-time demonstration tower crane height under hook and dolly operation amplitude.If testing precision is not high, may exists the excessive or trolley travelling amplitude of lifting altitude to surpass to require and cause crane accidents.The kind of drive of the multi-functional limiter that is adopted on the market at present all is to adopt gear transmission mode, the employing metal gear that has, the employing organic material gear that has basically; But adopt such kind of drive to have a unavoidable defective undoubtedly; Be the backlash of gear and gear engagement, when gear was constantly realized forward and backward, error was amplified gradually; Can cause detecting inaccurate, the generation that possibly cause the accident at any time.Though can carry out the elimination in gap through some modes, or be a large amount of increase costs, or be the restriction of restricted device inner space layout and can't arranging.Thought of the present invention is to adopt the metal gear of usual manner processing; Carry out adhering to of flexible material on its surface; Can eliminate the gap so on the one hand, avoid gear positive and negative then accumulated error occurs, on the other hand because gear surface belongs to flexible material; Can be owing to not very close to each other between the driving gear and can't realize gear transmission yet; Behind the gear surface fret wear, can realize automatic compensation function, the secondary that when gear wear is serious, carries out the gear surface material adheres to, and saves input cost.
Above content is to combine optimal technical scheme to the further explain that the present invention did, and can not assert that the practical implementation of invention only limits to these explanations.Under the present invention, the those of ordinary skill of technical field, under the prerequisite that does not break away from design of the present invention, simple deduction and replacement can also be made, all protection scope of the present invention should be regarded as.
