Abstract
The utility model discloses a rotating mechanism of guide-vane for fan which belongs to the control mechanism of the guide vane. The ordinary guide-vanes or fan rotating mechanisms adopt linkage rings which are arranged on the outside of a casing or inner linkage rings which are arranged on a center bearing, and the other end of blades is a sliding bearing which is arranged in the punching hole of the casing. The major defect is that the ordinary guide vanes or fan rotating mechanism is hard to maintain, and the appearance of the casing is untidy. In the utility model, an actuator on the outside of the casing is adopted to drive initiative blades, passive blades are driven to move by a rocker arm, a conical roller and linkage rings, which are arranged on a small shaft which is arranged on the bottom of guide blades, the outside of the blades adopt a sliding block or a bearing, the casing can be horizontally divided into two equal parts, that is the upper half and the lower half. The structure is convenient to decompose and favorable to on-site repair.
Description
The utility model belongs to the stator regulating and controlling mechanism.
The rotating mechanism of at present general blower fan stator or air door, employing is located at the outer interlock ring of casing or has the interior interlock ring of centre bearing, the blade the other end is the sliding bearing that is provided with in the casing punching, its major defect is be difficult to realize dividing in the level of casing, be unfavorable for field maintenance, if must establish timesharing in the level, decomposition technique is also very complicated; In addition, outer interlock ring makes the profile of blower fan very irregular, and is subjected to extraneous bump easily and damages.To the rotor of two fulcrums, except that air door, adjustable guide vane can't be provided with centre bearing.
The purpose of this utility model is a kind of blower fan stator rotating mechanism of dividing in the casing level be convenient to of design.
Technical conceive of the present utility model and embodiment are described below:
Description of drawings:
Fig. 1 is a blower fan stator rotating mechanism schematic representation.
Wherein: 1-positioning wire 2-slide block (or bearing)
The passive stator 4-of 3-interlock ring
5-conical roller 6-rocking arm and bulb
The outer casing of casing 9-in the 8-
Fig. 2 is that initiatively stator, passive stator assemble schematic representation.
Wherein: 7-is stator initiatively
Fig. 3 is an active stator apex structure schematic representation.
Blower fan stator rotating mechanism is by the active stator, passive stator and transmission part are formed, it is characterized in that in blower fan one circle stator, initiatively a stator (7) and an a plurality of passive stator (3) being arranged, active stator top is stretched out little axle and is linked to each other with the key final controlling element outer with being located at casing, the little axle in passive stator top is installed in the groove of outer casing (9) with slide block (or bearing) (2), with positioning wire (1) slide block (or bearing) and stator are fused, on, second is divided into two groups, the inboard little axle of stator is equipped with rocking arm and bulb (6), stir interlock ring (4), the interlock ring is around the rotational of blower fan, the interlock ring is made and is divided in the level, shared six pairs of conical rollers (5) location, the little axle of conical roller is fixed on the interior casing (8), and six of corresponding conical roller little axle places open six circumferential holes on the interlock ring.
The blower fan stator rotates by being located at the outer final controlling element of casing and drives active blade (7), stirs interlock ring (4) by rocking arm and bulb (6) on the inboard little axle of active blade, makes its rotational that centers on blower fan, reaches the purpose that stator rotates.
The advantage of this practical heart type is to adopt the stator assembling of this structure can make outer casing make separation structure in the level, is permitted directly outer casing to be decomposed by dividing in the level separately; Because the interlock ring also is separation structure in the level, as long as middle minute bolt of interlock ring pulled down, also can carries out easily inside and outside casing and decompose simultaneously. Good packaging technology has been guaranteed with slide block or bearing and positioning wire in the stator top, and each blade fit-up gap is little, and rotates flexibly again. This structure blower fan profile is neat, and globality is good.
