Abstract
The invention discloses an oil-cooled motor of large and medium equipment, which comprises a sealed motor shell (1) and a shaft (4), wherein the motor shell (1) is immerged in cooling oil of an oil box (5) of the equipment, an installing device installed on the box wall of the oil box (5) of the equipment is arranged on the motor shell (1), and the shaft (4) is outwards protruded out of the box wall of the oil box (5). The oil-cooled motor is mainly applied to large and medium machines, such as an injection molding machine and the like, which are generally provided with an oil hydraulic system per se, and the volume of the oil box of the oil hydraulic system is much larger than the volume of the motor, so that the normal working of the oil box can not be influenced after the motor is installed. By adopting the integrated installing structure of the motor and the oil box, not only the oil-cooled motor is convenient to install and the installing space is saved, but also the cooling efficiency can be improved. Meanwhile, the structure of the motor is compact, materials are reduced, and the cost is lowered.
Description
Technical field
The present invention relates to machine field, particularly be used for big-and-middle-sized machinery (promptly large and medium-sized), like the oil-cooled motor of plant equipment such as injection molding machine.
Background technology
Big-and-middle-sized machinery of the prior art generally is meant the large and medium-sized plant equipment that carries oil hydraulic system.Motor will inevitably produce a large amount of losses as the power tool of energy converting between mechanical when work, these losses finally all can become heat, and the temperature of motor is raise.In order to make motor ability operate as normal, must adopt certain type of cooling to distribute these heats, motor temperature is controlled in certain temperature range.At present, the type of cooling of motor generally has two kinds of air-cooled and oil coolings.The motor housing outside of motor with air cooling is provided with fan housing, and the centrifugal blower that is provided with through motor one end sucks cold air, and directly air-cooled via the air channel that is provided with on the fan housing, and the air discharge motor that will have the motor internal heat is external.But the volume that being provided with of fan housing increased motor, need bigger installing space, and the noise during the centrifugal blower operation is bigger, cooling effectiveness is low, in case blower fan breaks down, then motor can't operate as normal.On the one hand; The type of cooling of the oil-cooled motor of prior art generally realizes through the logical oil cooled method of inner chamber; Though it is air-cooled that its cooling effectiveness is much higher than,, need the independent circulatory system to come inner chamber is carried out fuel feeding; It is high to have increased cost and its seal request, and very inconvenience is installed.On the other hand, big-and-middle-sized machinery of the prior art like injection molding machine etc., generally all carries oil hydraulic system, and the volume of its fuel tank is bigger, and unreasonable being used is a kind of waste.
Summary of the invention
Technical problem to be solved by this invention is: a kind of oil-cooled motor of saving installing space, big-and-middle-sized equipment that cooling effectiveness is high is provided.
The present invention addresses the above problem the technical scheme that is adopted: a kind of oil-cooled motor of big-and-middle-sized equipment; The motor housing, the axle that comprise sealing; Described motor housing is dipped in the cold oil of fuel tank of equipment; Described motor housing is provided with and is used to be installed in the erecting device on the equipment fuel tank tank wall, and described axle evagination is outside the fuel tank tank wall; Described erecting device comprises the forward flange that is connected in the motor housing upper end, is provided with seal between described motor housing and the forward flange; Described forward flange is connected in the fuel tank external box wall, is provided with seal between described forward flange and the fuel tank external box wall; One side of described forward flange is provided with the wire hole that connects side from the forward flange bottom, and power supply lead wire that is connected with described motor and encoder lead-in wire stretch out forward flange through described wire hole.
Compared with prior art; The invention has the advantages that: this oil-cooled motor is mainly used in big-and-middle-sized machinery, and like injection molding machine etc., these plant equipment generally have the oil hydraulic system that carries; The volume of the volume ratio motor of its fuel tank is much bigger, so can not influence the operate as normal of fuel tank behind the installation motor.Adopt the incorporate mounting structure of above-mentioned motor and fuel tank, both easy for installation, saving installing space can improve cooling effectiveness again.Simultaneously, the compact conformation of this motor, reduced material, reduced cost.
Forward flange through placing the fuel tank outer wall and fuel tank are tightly connected can the proportionately installation of motor, installs very conveniently, does not need other electric machine mounting devices such as mount pad.
The wire hole outlet that power supply lead wire and encoder lead-in wire can be provided with through forward flange, it is more reasonable to go out line position, and the insulation effect of electric wire is also better.
Description of drawings
The structural representation of the oil-cooled motor of the big-and-middle-sized equipment of accompanying drawing the present invention.
Among the figure: 1 motor housing, 2 stators, 3 rotors, 4 armature spindles, 5 fuel tanks, 6 rear flanges, 7 stator line bags, 8 encoder stators, 9 encoder rotors, 10 forward flanges, 11 bearings, 12 Sealing shield rings, 13 wire holes, 14 power supply lead wires, 15 encoders lead-in wire.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described.
The oil-cooled motor of a kind of big-and-middle-sized equipment as shown in the figure; Comprise motor housing 1, axle 4; The stator 2 that is installed on the axle 4 is fixedly connected with stator line bag 7 with the rotor 3, stator 3 two ends that are installed on the stator, and rotor 3 two ends are provided with the gimbal that reduces rotor 3 vibrations; The lower end of motor housing 1 and rear flange 6 are tightly connected through the O RunddichtringO, and rear flange 6 is connected with axle 4 through bearing; Motor housing 1 is dipped in the cold oil of fuel tank 5 of equipment; The upper end of motor housing 1 and forward flange are tightly connected through the O RunddichtringO; And forward flange 10 is connected with axle 4 through bearing 11; Axle 4 tops are provided with Sealing shield ring 12, and by the sealing ring sealing, forward flange 10 is sealedly attached to outside the tank wall of fuel tank 5 through the O RunddichtringO.
Motor is connected with power supply lead wire 14 and encoder lead-in wire 15, and encoder stator 8 is installed on the forward flange 10, and encoder rotor 9 is installed on the axle 4; One side of forward flange 10 is provided with the wire hole 13 that connects side from forward flange 10 bottoms, and power supply lead wire 14 and encoder lead-in wire 15 stretch out forward flange 10 through wire hole 13.
