Abstract

The utility model discloses a pull-free initiator which comprises a machine shell. The machine shell is made of nylon and is formed in a vulcanization mode. A driving shaft is installed on the inner side of the machine shell, a driving gear is installed on the driving shaft, a clutch shaft penetrating out of the machine shell is installed on the machine shell, a clutch gear is installed on the clutch shaft located on the inner side of the machine shell and is meshed with the driving gear, an initiating gear is installed on a part, located on the outer side of the machine shell, of the clutch shaft, a clutch handle is hinged to the outer side of the machine shell, and the inner end of the clutch handle is connected with the initiating gear. By means of the structure, an engine is reliably started, meanwhile, the structure is compact, simple and novel, the occupied space is small, and the strength of the machine shell is guaranteed. Due to the fact that the pull-free initiator is made of the nylon material, the pull-free initiator is light in weight, low in production cost and high in safety performance.

Description

Exempt to draw starter

Technical field

The utility model belongs to technical field of engines, specifically, relates in particular to a kind of diesel oil or petrol engine and exempts to draw starter.

Background technique

At present, diesel engine on market is of a great variety, generally all has electronic starter on some passenger traffics, goods stock, yet most farm tractor is all also to adopt the mode of hand speedup to start, this original Starting mode exists many inconvenience and unsafe factor, causes the accident of personal disability to happen occasionally because starting diesel engine; In daily production process, also there is the people to change the diesel engine on farm tractor into electric startup formula, this kind mode not only cost is high, and working life is limited, specifically, because the operation cycle of farm tractor is seasonal often, the most of the time in 1 year is left unused aside, electricity starts the battery of using in the situation that long-term placement is very easily aging, and this will directly cause the inefficacy of electric Starting mode.In order to meet the needs of production, the swinging-free starter that is specifically applied to diesel engine miscellaneous has appearred on market, although these swinging-free starters are widely used, also exist some problems in agricultural equipment Diesel engine.At first, the interiors of products structure is very complicated, small product size is large, poor safety performance, the startup axle of present swinging-free starter does not mostly separate with the diesel engine input shaft later at diesel engine starting on the other hand, in the process of diesel engine running, start axle and be in idling conditions always, this makes the startup axle do a large amount of unnecessary runnings, thereby has greatly shortened the working life that starts axle and even swinging-free starter, again, what existing starter shell adopted is that metallic material is made, and cost is high.

The model utility content

The utility model purpose is to provide a kind of novelty simple in structure, and what can make that engine reliable starts exempts to draw starter.

For achieving the above object, the utility model provides a kind of starter of exempting to draw, comprise casing, its main points are: at this internal side of shell, driving shaft is installed, on this driving shaft, driving gear is housed, the clutch shaft that passes this casing is installed on described casing, clutch gear is installed being positioned on the clutch shaft of this internal side of shell, this clutch gear and the engagement of described driving gear, on the clutch shaft that is positioned at this casing outside, starter receiver is installed, the described casing outside is hinged with clutch handle, and this clutch handle is inner to be connected with described starter receiver.Adopt above structure, when reliably realizing engine start, compact structure of the present utility model takes up room little, novelty simple in structure.

As preferably: described casing adopts the nylon sulfidization molding, when guaranteeing case strength, adopt nylon material make of the present utility model lightweight, cost of production is low.

As preferably: described clutch handle is arranged on the described casing outside through rotating shaft, and the inner of this clutch handle is against on the tooth of described starter receiver.Adopt above structure, pull clutch handle and can remove spacing to starter receiver, so, starter receiver can freely rotate, and realizes reliably the startup of motor.

As preferably: be set with the return torsion spring in described rotating shaft, this return torsion spring one end leans against on described casing, and the other end leans against on described clutch handle.Adopt above structure, unclamp clutch handle, under the effect of return torsion spring, thereby the clutch handle return is realized spacing to starter receiver.

As preferably: be provided with fixing bolt at described internal side of shell, this fixing bolt is near the inwall of described casing.

The beneficial effects of the utility model are: the utility model compact structure, can realize reliably the startup of motor, and adopt the nylon casing, thereby make quality of the present utility model greatly alleviate; Have that novelty simple in structure, cost are low, the Safety performance high.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the rear view of Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

as depicted in figs. 1 and 2 a kind of exempts to draw starter, comprise casing 1, described casing 1 adopts the nylon sulfidization molding, in this casing 1 installed inside, driving shaft 2 is arranged, on this driving shaft 2, driving gear 3 is housed, the clutch shaft 4 that passes this casing 1 is installed on described casing 1, on the clutch shaft 4 that is positioned at this casing 1 inboard, clutch gear 5 is installed, this clutch gear 5 and described driving gear 3 engagements, on the clutch shaft 4 that is positioned at this casing 1 outside, starter receiver 6 is installed, described casing 1 outside is hinged with clutch handle 7, this clutch handle 7 is inner to be connected with described starter receiver 6.

It can also be seen that in Fig. 1: described clutch handle 7 is arranged on described casing 1 outside through rotating shaft 8, the inner of this clutch handle 7 is against on the tooth of described starter receiver 6, be set with return torsion spring 9 in described rotating shaft 8, these return torsion spring 9 one ends lean against on described casing 1, the other end leans against on described clutch handle 7, be provided with fixing bolt 10 in described casing 1 inboard, this fixing bolt 10 is near the inwall of described casings 1.
