Abstract
A kind of profile of tooth Conncetion cimension adjustable crank structure, is characterized in that: described profile of tooth Conncetion cimension adjustable crank structure, is Split type structure, comprises the large end of crank, crank small end, bolt, nut; Wherein: one end of the large end of crank is with large through hole, and the other end bottom is with mounting hole, and mounting hole upper edge is with dentation structure upwards; Crank small end one end is with the hole of installation shaft, and the other end top is with attachment hole, and the edge of attachment hole bottom is with downward dentation structure; The large end of crank dentation structure upwards and the downward dentation structure of crank small end are adjacent to installation, and screw bolt and nut connects through mounting hole locking.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 profile of tooth Conncetion cimension 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 to save the process-cycle, having shortened the test period, and spy provides a kind of profile of tooth Conncetion cimension adjustable crank structure.
The utility model provides a kind of profile of tooth Conncetion cimension adjustable crank structure, it is characterized in that: described profile of tooth Conncetion cimension adjustable crank structure is Split type structure, comprises the large end 1 of crank, crank small end 2, bolt 3, nut 4;
Wherein: one end of the large end of crank 1 is with large through hole, and the other end bottom is with mounting hole, and mounting hole upper edge is with dentation structure upwards; Crank small end 2 one end is with the hole of installation shaft, and the other end top is with attachment hole, and the edge of attachment hole bottom is with downward dentation structure; The large end of crank 1 dentation structure upwards and the downward dentation structure of crank small end 2 are adjacent to installation, and bolt 3 and nut 4 are connected through mounting hole locking.
Described bolt 3 and the number of nut 4 are 1 ~ 3.
Crank is changed into split type, by bolt together with tooth is assembled into.By the structural type of bolt together with being assembled into tooth, this structure can realize the change of crank size, and processing and easy to assembly.
Advantage of the present utility model:
Profile of tooth Conncetion cimension 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.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is crank assembling schematic diagram.
