Abstract
The crankshaft of diaphragm pump relates to an improvement to the crankshaft structure of the diaphragm pump. The utility model provides a diaphragm pump crankshaft which has a simple structure and a good supporting performance. The utility model includes a left single crutch shaft, a right single crutch shaft and a mid single crutch shaft, the structural points of which are: the left and right ends of the left single crutch shaft are respectively dynamic input shaft end, supporting bearing, connection bearing and coupling spline; the left and right ends of the right single crutch shaft are respectively coupling spline, connection bearing and supporting bearing; two ends of the mid single crutch shaft are respectively connection bearing and coupling spline; the coupling splines, between the left single crutch shaft and the mid single crutch shaft, and between the mid single crutch shaft and the right single crutch shaft, are respectively meshed into an integral part by the drum gear coupling.
Description
Technical field:
The utility model relates to the improvement of the crankshaft structure of diaphragm pump.
Background technique:
One of important large component of diaphragm pump is a bent axle, and its bent axle is an axle, and has three place's flex points; Therefore, the structure more complicated, difficulty of processing is bigger.This bent axle is strong by technical force often, the more perfect large enterprise of equipment finishes.In addition, during use, this structure adopts two supports, intensity to be difficult for guaranteeing; Adopt four supports again bent axle to be caused the location.
The model utility content:
The utility model is exactly at the problems referred to above, and a kind of bent axle of simple in structure, diaphragm pump that support performance is good is provided.
The utility model adopts following technological scheme: the utility model comprises that a left side turns singly that axle, the right side singly turn axle, the centre singly turns axle, left end, right-hand member that axle is singly turned on its structure outline left side are respectively power input shaft end, spring bearing, connection bearing and connect spline, right left end, the right-hand member that singly turns axle is respectively and connects spline, connection bearing and spring bearing, and middle two ends of singly turning axle are respectively connection bearing, connect spline; A left side is turned singly that axle singly turns between the axle with the centre, singly turn spool the centre with the right side and is singly turned between the axle respectively and will connect spline by crown gear coupling and be meshed and be integral.
The beneficial effects of the utility model:
1, simple in structure:
The utility model turns the bent axle that axle forms one by three and replaces existing integral one-piece crankshaft, and it is just much simple than existing crankshaft structure that each turns axle, and easy manufacturing, can improve Enterprises'Competitiveness;
2, be convenient to support:
Bent axle of the present utility model can singly turn the spring bearing of the power input shaft end of axle by a left side, the right spring bearing that singly turns axle is supported in respectively on the bearing, has guaranteed the stable support of bent axle.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprise a left side singly turn the axle 8, the right side singly turn the axle 2, the centre singly turn the axle 7, left end, right-hand member that axle 8 is singly turned on a left side are respectively power input shaft end 10, spring bearing 9, connection bearing 3 and connect spline 4, right left end, the right-hand member that singly turns axle 2 is respectively and connects spline 4, connection bearing 3 and spring bearing 1, and middle two ends of singly turning axle 7 are respectively connection bearing 3, connect spline 4; A left side turns singly that axle 8 singly turns between the axle 7 with the centre, the centre will connect spline 4 by crown gear coupling 5 respectively between singly turning axle 7 and the right side singly turning spools 2 and be meshed and be integral.
During use, the utility model left side turned singly axle 8, centre singly turn axle 7, the right side is singly turned axle and 2 is successively placed on the bearing support block 6, and axle 8 and centre are singly turned in a left side singly turn axle 7, the right side and singly turn axle 2 and centre and singly turn spools 7 and connect respectively and get final product by connecting crown gear coupling 5.
