Abstract
The utility model discloses an electromagnetic thruster, being a thruster device used for executing the brake of a power mechanism rotary component, which assembles a single-winding coil in an inner cavity of a housing, the inner cavity of the coil passes through a push rod provided in a slide manner with a connection iron core at the top along the axes line of the housing, and the housing is fixed with a bolt at the housing bottom; besides, a bracket and a top seal cover and so on are further arranged on the bottom. Solving the problems such as the hydraulic thruster has a large electricity consumption and an oil leakage, the connection between the electromagnetic driver housing and the cover bolt is apt to break, the two-winding coil has a large electricity consumption and a small maintaining force, and the structure is complex by assembling a steel sleeve on the slide surface of the push rod, the utility model is a thruster device having the advantages of simple structure, easy production and convenient operation.
Description
Technical field
The utility model relates to a kind of electromagnetic driver, mainly is applicable to a kind of pusher assembly of dynamic power machine rotating part execution braking.
Background technology
At present, when industries such as industrial and mineral, harbour, building mechanical and power equipment rotating part commonly used is carried out braking, the power hydraulic pressure pusher brake systems that adopt, this system realize that braking then is to promote device by fluid pressure type to promote it and joined link component and execution unit is finished more.Fluid pressure type promotes device and then by driven by power driven by motor driving-chain hydraulic pressure transfer is converted to mechanical braking thrust, and it is many that it drives link, and power consumption is big, easy oil leakage.In addition, China Patent No. is that ZL99201446.8 discloses " a kind of drive unit of brake " technology, it is to promote to replace hydraulic driver with electromagnet structure, has certain advance, but also there is weak point, close face and install steel bushing additional, complex structure with iron core, the relevant cunning of guide post as push rod; Adopt to drive and keep the double winding coil, power consumption is many and maintenance energy is little, makes difficulty; Housing top cover and body do not belong to one, fracture easily with bolted; Its stroke is short simultaneously, and stroke is 15～60mm.
Summary of the invention
The purpose of this utility model is exactly for solving above-mentioned deficiency, and slidingly close face and need not to assemble steel bushing with relevant for people provide a kind of push rod, employing simplex winding coil, housing top cover and body are one, the electromagnetic driver device of stroke length.
The purpose of this utility model is achieved in that assembles the simplex winding coil with effective turn in the inner walls chamber, the inner chamber of winding coil, passing its boss hole and oilless bearing cunning along the housing axial line attaches together and joins push rod, the push rod bottom is the iron core that is coarser than push rod itself, it is fastening with it that housing lower surface and drain pan upper surface contact with bolt, and the drain pan bottom surface is fixed with base support, on the push rod of housing top cover outside, oil seal gasket and sealing ring are housed, are fitted on the housing top cover with the bolted gland.
Housing top cover and its body and drain pan bottom and its body are cylindrical as one.
The utility model has the advantages that the relevant face of being slidingly matched with it of push rod need not to adorn steel bushing, simple in structure; Adopt the simplex winding coil, power saving is easily done; Housing top cover and its body are integral, and do not rupture without bolted; Stroke is long, and its stroke is 30～160mm.It is a kind of desirable pusher assembly simple in structure, easy to manufacture, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
