Abstract
The invention provides a direct-drive wind driven generator structure which comprises a base, a rotor, a conical support and a bearing device, wherein the bearing device consists of an inner ring, a flange, a double-row conical bearing and a braking device; a wide end of the conical support is connected with the base by a bolt, and a narrow end of the conical support is connected with an inner circle of the double-row conical bearing by a bolt; the rotor is fixedly connected with the flange in the bearing device through a bolt II; and the inner ring is in interference fit with the inner circle of the double-row conical bearing, the inner circle of the bearing is heated by a high-frequency sensing heater or heating furnace, and the bearing is mounted on the inner ring. According to the invention, the existing structure is optimized, thus the mounting efficiency is remarkably improved, and the generator weight and the production cost are reduced in comparison with the existing scheme.
Description
Technical field
The present invention relates to a kind of direct wind-driven generator structure, more specifically say to relate to a kind of direct wind-driven generator bearing structure.
Background technique
Main bearing for directly driven wind generators is a solid bearing now, generally adopts Bearing Steel or steel for carburizing manufacturing, because this type price of steel product is higher; The main bearing that causes the whole supply of material to come costs an arm and a leg, and for solving the too high problem of bearing price, designs the special construction bearing afterwards; Being about to a part of bearing inner race steel substitutes with spheroidal graphite cast iron; Adopt the interference trim designs, bearing inner race and nodular iron casting interference are assembled into an integral body, under the constant situation of integral rigidity; It is about 50% that bearing steel weight reduces, and the bearing integral expense significantly reduces.In fact there are many defectives in this kind structural design in the practical set process, and at first because interference build-up member and former taper support (inner stator) combine together, indexs such as general assembly body weight and installation dimension all surpass general factory crane hoisting weight and the restriction of factory building transportation clearance; Secondly because mounting fixture is limited by installing space; Bearing inner race two parts up and down must separate hot jacket, can not whole heating install, and causes manufacturing efficiency to decline to a great extent; Influence is produced in batches; This structure need increase brake system (brake disc and break) at motor internal at last, causes motor weight to increase, and produces and the installation cost rising.
Summary of the invention
The object of the present invention is to provide the direct wind-driven generator structure that a kind of installation dimension is little, in light weight, installation efficiency is high.
The present invention realizes through following technological scheme.
A kind of direct wind-driven generator structure comprises taper support, rotor, also comprises bearing means, and said bearing means and taper are supported for the structure of non-Unitary.
The wide end that said taper is supported is fixedly connected with support, and the narrow end that taper is supported is fixedly connected with bearing means.
Said bearing means is fixedly connected through the connecting bolt II with rotor, and is provided with connecting plate with the contacted side of rotor.
Be provided with biserial conical bearing, flange, interior ring and braking device in the said bearing means; In encircling in said biserial conical bearing is arranged on; Flange is connected with the biserial conical bearing through the fixed connection mode; Braking device is fixedly connected with flange.
Said flange is two identical parts up and down.
Said braking device is fixedly mounted on the top of said bearing means.
Said braking device comprises break, brake disc, brake hoop; Said break is fixed on the brake hoop, and brake disc is fixedly connected on the flange, encircles in brake hoop is fixedly connected on.
Be provided with seal arrangement between said brake hoop and the said flange.
Beneficial effect of the present invention: through bearing means and taper support be set to the structure of non-Unitary after; Effectively reduced the overall dimensions of parts; Be implemented in the quick assembling of erecting bed; Do not receive the space of operation site and the restriction of setting tool size, effectively reduced installation difficulty, improved installation efficiency; After simultaneously braking device being mounted to the bearing means top, saved the motor internal braking, the parts overall weight significantly reduces.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
