Abstract
A kind of thread type size adjustable crank structure, is Split type structure, comprises the large end of crank, crank small end, locking key, nut; Wherein: the large end band of crank has interior threaded hole, crank small end with external thread structure, crank small end axis with keyway, with through hole in locking key, on nut with lock silk hole; The interior threaded hole that the large end band of crank has and crank small end with external thread structure be connected, locking key is positioned at keyway, nut sleeve, on the external thread structure of locking key and crank small end, is connected, and after locking, lock silk is through the lock silk hole on nut and the through hole in locking key.Advantage of the present utility model: structure is simple, be convenient to processing, can ensure quality of processing, processing cost is low, and assembling simply solves the problem that crank size regulates simultaneously, and this structure can regulate size without the need to decomposing adjusting mechanism at any time.
Description
Technical field
The utility model relates to size adjustable crank structure field, particularly a kind of thread type size adjustable crank structure.
Background technique
The Rule adjusting of compressor stator blade, need to continue to optimize and improve in test and using process, the requirement on machining accuracy of adjusting mechanism spare part is high, the process-cycle is longer, and therefore every suboptimization all needs to drop into more material resources and time.
Model utility content
The purpose of this utility model is the size being convenient to regulate crank, realizes the change of Rule adjusting, saves the process-cycle, and shorten the test period, spy provides a kind of thread type size adjustable crank structure.
The utility model provides a kind of thread type size adjustable crank structure, it is characterized in that: described thread type size adjustable crank structure is Split type structure, comprises the large end 1 of crank, crank small end 2, locking key 3, nut 4;
Wherein: the large end 1 of crank with interior threaded hole, crank small end 2 with external thread structure, crank small end 2 axis with keyway, with through hole in locking key 3, on nut 4 with lock silk hole;
The large end 1 of crank with interior threaded hole and crank small end 2 with external thread structure be connected, locking key 3 is positioned at keyway, nut 4 is enclosed within the external thread structure of locking key 3 and crank small end 2, is connected, and after locking, lock silk is through the lock silk hole on nut 4 and the through hole in locking key 3.
The number of described locking key 3 is 1.
Crank is split type, is threaded connection and is assembled into together, carrys out locked structure by locking key.Be threaded connection and be assembled into together, carry out locked structural type by locking key, this structure can realize the flexible change of crank size, and regulable control precision is high, each adjustment pitch, and processing and easy to assembly.
Advantage of the present utility model:
Thread type size adjustable crank structure described in the utility model, structure is simple, is convenient to processing, quality of processing can be ensured, processing cost is low, and assembling simply solves the problem that crank size regulates simultaneously, and this structure can regulate size without the need to decomposing adjusting mechanism at any time.
