Abstract
The utility model relates to a fixed structure for cooperation of a ventilator impeller and motor shaft extension. The structure is provided with the motor shaft extension with a conical surface structure, and the motor shaft extension is connected with a taper sleeve in a matched mode through the conical surface; the outer circle of the taper sleeve is sleeved with an impeller shaft sleeve; the shaft head portion, extending out of the impeller shaft sleeve, of the motor shaft extension is provided with threads and connected with double nuts and double lock washers through the threads; a clamping groove is formed between the motor shaft extension and the shaft head, and a clamping ring is arranged in the clamping groove. The structure can effectively solve the problem that disassembling and assembling between traditional cylindrical shaft extension and the impeller shaft sleeve are difficult, reduce impact on the motor shaft extension and bearings in the process of disassembling and assembling the impeller and effectively protect the motor shaft extension and the bearings against damage.
Description
Technical field
The utility model belongs to ventilator technical field, is fixed structure especially for a kind of fan impeller and motor-shaft extending on the counter-rotating main fan of colliery.
Background technique
In the prior art, colliery adopts direct connection structure conventionally by counter-rotating main fan impeller and necessary electromotor shaft extension, and its motor adopts cylindrical shaft extension, and impeller sleeve endoporus is circular, transition fit between the two.When impeller assembling, need heating axle sleeve, axle sleeve is sleeved on motor-shaft extending after expanding.When dismounting, still need to heat impeller sleeve, just can extract impeller.This kind of structure easily pulled motor-shaft extending, and motor bearings is caused to damage, reduces bearing working life.
Model utility content
The purpose of this utility model is to provide a kind of easy accessibility, and can protect fan impeller and the motor-shaft extending that motor-shaft extending, bearing are without prejudice to be fixed structure.
Realizing the technological scheme that the purpose of this utility model takes is: this structure has a motor-shaft extending with cone structure, motor-shaft extending is connected with taper sheath by cone match, on the cylindrical of taper sheath, be set with impeller sleeve, the spindle nose position that motor-shaft extending stretches out outside impeller sleeve is provided with screw thread, and double nut and two lock washers are threaded connection, between motor-shaft extending and spindle nose, establish draw-in groove, snap ring is housed in draw-in groove.
Described taper sheath is cylindrical body, and its inner headed face is cone structure.
Fan impeller and the motor-shaft extending made according to such scheme are fixed structure; by improving the mode that is fixed of motor-shaft extending and impeller; solve traditional round axis of a cylinder and stretched dismounting difficult problem between impeller sleeve; reduce the impact of impeller demolition to motor-shaft extending and bearing, thereby effectively play the practical effect of protecting motor-shaft extending and bearing not to suffer damage.This structure easy accessibility, and can effectively prevent impeller under responsive to axial force, or coming off of causing of the locking inefficacy of shaft extension lock washer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, fan impeller of the present utility model and motor-shaft extending cone match fixed structure, this structure has a motor-shaft extending 3 with cone structure, motor-shaft extending 3 is connected with taper sheath 2 by cone match, on the cylindrical of taper sheath 2, be set with impeller sleeve 1, spindle nose 7 positions that motor-shaft extending 3 stretches out outside impeller sleeve 1 are provided with screw thread, and have been threaded connection double nut 6 and two lock washer 5, between motor-shaft extending 3 and spindle nose 7, establish draw-in groove 8, snap ring 4 is housed in draw-in groove 8.Described taper sheath 2 is cylindrical body, and its inner headed face is cone structure.When installation, taper sheath 2 is sleeved on the motor-shaft extending 3 of motor 9, impeller sleeve 1 is enclosed within on taper sheath 2, and snap ring 4 is packed in draw-in groove 8, fixing snap ring 4 outer rings and impeller sleeve 1.Snap ring 4 outsides are fixed by the screw thread on spindle nose 7 with double nut 6 and two lock washer 5.When impeller sleeve 1 is dismantled, unload double nut 6, two lock washer 5 and snap ring 4 with spanner, just can extract impeller sleeve 1, strike without heating hammer.
Claims (2)
1. a fan impeller and motor-shaft extending are fixed structure, it is characterized in that: this structure has a motor-shaft extending with cone structure, motor-shaft extending is connected with taper sheath by cone match, on the cylindrical of taper sheath, be set with impeller sleeve, the spindle nose position that motor-shaft extending stretches out outside impeller sleeve is provided with screw thread, and be threaded connection double nut and two lock washer, and between motor-shaft extending and spindle nose, establish draw-in groove, snap ring is housed in draw-in groove.
