Abstract
The utility model relates to the novel normally open clutch of a kind of microtilling machine, and it is made up of parts such as clutch housing, fixed tray, active friction plate, driven friction disk, Returnning spring, platens.Platen is provided with external splines and gets rid of oil groove, driven friction disk is provided with internal spline, platen and driven friction disk pass through spline joint, when loosening the clutch, under Returnning spring spring-force driven dual, platen outwards moves, frictional force is produced between platen and driven friction disk, driven friction disk is outwards moved, active friction plate external tooth is fastened on the groove of clutch housing, its frictional force produces braking action to active friction plate, there is relative movement between active friction plate and driven friction disk and normally open clutch is thrown off automatically, under the influence of centrifugal force, lubricant oil in the middle part of clutch can be lubricated active friction plate and driven friction disk by the oil groove that gets rid of on platen, make friction plate not easy to wear, thus realize the thorough separation of normally open clutch.
Description
Technical field
The utility model relates to a kind of clutch of function agricultural cultivator actuating unit, particularly relates to a kind of novel normally open clutch of microtilling machine.
Background technique
Along with the development of rural economy, microtilling machine in mountain area, hills, booth vegetable, the region such as orchard obtain and promote the use widely.General microtilling machine all adopts Normally closed type clutch, and safety in utilization is poor, in recent years many local security incidents all occurring microtilling machine inflicting bodily injury.In view of this kind of situation, on April 25th, 2013, country promulgated " machinery industry standard of microtilling machine " (JB/T10266-2013) again, and new standard proposes strict demand to the clutch in the actuating unit of microtilling machine.To this, existing microtilling machine has also gradually adopted normally open clutch, but be also difficult to the Safety performance requirement meeting microtilling machine new standard in using, it mainly has the following disadvantages: 1, existing normally open clutch, in clutch disengage process, can not automatically throw off between friction plate, and lubricate insufficient, have adhesion or traction phenomenon, cause clutch separation not thoroughly, friction disc wear is fast, do not reach the requirement of NBS; 2, in prior art, part producer arranges clutch brake on the main shaft of transmission device or on the thrust disc of clutch, force parking clutch, this pressure clutch mode, does not also automatically throw off between its friction plate, still there is lack of lubrication, friction disc wear can be caused, and force produce greater impact power during clutch, handrail is up lifted suddenly, uses during operation and still there is larger danger.
Summary of the invention
The purpose of this utility model is the novel normally open clutch of a kind of microtilling machine proposed for the deficiencies in the prior art.The technical solution of the utility model is the internal structure changing existing normally open clutch, in clutch separation process, utilize the frictional force that between clutch internals, relative movement produces, friction plate is thrown off automatically, improve the lubricating condition between friction plate, reduce the wearing and tearing of friction plate, realize the thorough separation of clutch, thus the Safety performance requirement be up to state standards.
The technical solution of the utility model is achieved in that a kind of novel normally open clutch of microtilling machine, it is made up of parts such as clutch housing, fixed tray, active friction plate, driven friction disk, Returnning spring, platen, hexagon socket cap head screw, pads, it is characterized in that, active friction plate and driven friction disk are arranged alternately, the external tooth of active friction plate is fastened in the groove of clutch housing, drives active friction plate synchronous axial system and input power when clutch housing rotates; Platen is provided with external splines, gets rid of oil groove, and the internal spline of driven friction disk is connected with the external splines on platen, drives platen to rotate and outputting power when driven friction disk rotates; The internal spline of fixed tray and the external splines of platen are in axial sliding connection; Returnning spring is sleeved on platen, and spring-force driven dual is between fixed tray and platen, and hexagon socket cap head screw and pad are through fixed tray and be connected on platen, thus controls the position of platen movement backward.When loosening the clutch, under Returnning spring spring-force driven dual, platen outwards moves, frictional force is produced between platen and driven friction disk, driven friction disk is outwards moved, active friction plate external tooth is fastened on the groove of clutch housing, its frictional force produces braking action to active friction plate, there is relative movement between active friction plate and driven friction disk and normally open clutch is thrown off automatically, under the influence of centrifugal force, lubricant oil in the middle part of clutch can be lubricated active friction plate and driven friction disk by the oil groove that gets rid of on platen, make friction plate not easy to wear, thus realize the thorough separation of normally open clutch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
By reference to the accompanying drawings 1, the novel normally open clutch of the microtilling machine that the utility model provides, it is made up of parts such as clutch housing 1, fixed tray 2, active friction plate 3, driven friction disk 4, Returnning spring 5, platen 6, hexagon socket cap head screw 7, pads 8.Active friction plate 3 and driven friction disk 4 are arranged alternately, and the external tooth of active friction plate 3 is fastened in the groove of clutch housing 1, drive active friction plate 3 synchronous axial system and input power when clutch housing 1 rotates; Platen 6 is provided with external splines 61, gets rid of oil groove 62, and the internal spline of driven friction disk 4 is connected with the external splines 61 on platen 6, drives platen 6 to rotate and outputting power when driven friction disk 4 rotates; The internal spline of fixed tray 2 and the external splines 61 of platen 6 are in axial sliding connection; Returnning spring 5 is sleeved on platen 6, and spring-force driven dual is between fixed tray 2 and platen 6, and hexagon socket cap head screw 7 and pad 8 are through fixed tray 2 and be connected on platen 6, thus controls the position of platen 6 movement backward.When unclamping clutch, under Returnning spring 5 spring-force driven dual, platen 6 outwards moves, frictional force is produced between platen 6 and driven friction disk 4, driven friction disk 4 is also outwards moved, active friction plate 3 external tooth is fastened on the groove of clutch housing 1, its frictional force produces braking action to active friction plate 3, there is relative movement between active friction plate 3 and driven friction disk 4 and normally open clutch is thrown off automatically, under the influence of centrifugal force, lubricant oil in the middle part of clutch can by platen 6 get rid of oil groove 62 pairs of active friction plates 3 and driven friction disk 4 lubricates, make friction plate not easy to wear, thus realize the thorough separation of normally open clutch.
In addition, of the present utility modelly to be also advantageous in that, the novel normally open clutch of the microtilling machine provided, can rapid operation to be reached when operating and using, clutch is steady, the complete Safety performance requirement that can meet JB/T10266-2013 NBS, disability security incident when avoiding microtilling machine to operate.
