Find material of tall wear-resisting function from material the 2 structural appearance that are reasonable and certain toothed segmentFind material of tall wear-resisting function from material the 2 structural appearance that are reasonable and certain toothed segment and geometrical dimension
Show the toothed segment that uses on some gnathic type crusher, it is to use ZGMn13 commonly, its are main the characteristic is: Below wallop bear action, have case hardening , form hard the surface of wear-resisting, still can maintain its at the same time lining metal former some is capricious, reason it is the data of the most general a kind of wear-resisting that uses on crusher.
The appearance of cross section structure of toothed segment has flowing surface and tooth form face two kinds, latter is divided again for triangle and bodily form surface.
This design uses figure of structure of cross section of triangular toothed segment. The bracket of crusher is the spare parts with the simplest structure, but its effect is exceedingly main however. Having 3 action; normally is to transfer power, the power that its transfer returns big; than broken force even sometimes 2 it is an insurance action, when broken antrum falls to be not broken stock, go ahead of the rest of costal region board ruptures destroy, protect machine other spare parts not to happen thereby destroy; 3 it is to adjust a makings mouth volume.
When the machine works, cannot get lubricating very well between the scaleboard of bracket and its bearing, add dust to fall, actually so a kind of dry attrition is mixed between bracket and its gasket grind bead to wear away condition. Such, to the pressure of high load capacity of bracket, bring about bracket and bracket mat to wear away very quickly, service life is very low. The main effect that because the structure of this bracket is designed,should consider this parts also should consider his working environment.
Gnathic type crusher uses the join type of the head that press ancon and ancon mat, can divide for scroll model with slip model two kinds. Very large extruding force is delivered between bracket and gasket, get cycle
The gender pounds load. In wear away below concussion extruding action repeatedly religion fast, pursue especially what 8-2(a) place shows is slip model more serious. To improve transmission efficiency, decrease wear away, prolong its service life, can use the scroll that graph 8-2(b) shows structure. Bracket head is columnar face, gasket is plane. As a result of the two end of bracket ancon head surface is same and columnar watch
Face, become so bracket when the gasket surface of two end is mutual and parallel, the same diameter that bracket suffers round cylinder of bracket of force general edge, deliver with the perpendicular direction of gasket surface. In machine movement process, move another name for Hubei province swing part is very small, make the included angle of the ancon mat surface that two end prop up bracket very small, it is so in machine movement process, bracket and its ancon can maintain pure scroll between mat.Gnathic type crusher
