CN2530043Y - Three-gear series of single-cylinder diesel engine - Google Patents

Abstract

The utility model discloses a three-gear in train of a single cylinder diesel with the cylinder diameter of 80-92mm, comprising a crankshaft timing gear (1) on the crankshaft, an idle gear (2) fixed on an idle gear shaft of a main frame and a camshaft timing gear (3) on the camshaft. The crankshaft timing gear (1) is meshed with the idle gear (2) and the idle gear (2) is meshed with the camshaft timing gear (3). When the crankshaft rotates, the camshaft gas distribution timing operation is driven through the crankshaft timing gear (1), the idle gear (2) and the camshaft timing gear (3). The utility model has the advantages of simple structure, good process engineering, low investment, fast commission and low cost and can be produced by the manufacturer of the single cylinder diesel.

Description

Single cylinder diesel three gear trains

One, technical field

The utility model is a kind of three gear trains that cylinder diameter is 80～92mm type single cylinder diesel that are used for.

Two, background technique

Traditional cylinder diameter is that the single cylinder diesel gear transmission train of 80～92mm adopts five gear trains or six gear trains usually, be that crankshaft timing gear and crankshaft counterbalance gear are housed on the crankshaft of diesel engine, crankshaft timing gear is by being contained in the camshaft timing gear on the camshaft, the drive camshaft rotates, crankshaft counterbalance gear and balance shaft gear engagement, the drive trunnion shaft rotates, finish the work of each parts like this by each gear meshing, be provided with kick gear simultaneously, drive bent axle during diesel engine starting and rotate.The many complex structures of gear gear gear, the manufacture cost height.

Three, summary of the invention

The purpose of this utility model be exactly for cylinder diameter for the single cylinder diesel of 80～92mm provide a kind of simple in structure, compact, inherit the three gear trains that cost is low with the technology of single cylinder diesel gear train.

The utility model is made up of crankshaft timing gear, idle gear, camshaft timing gear etc., crankshaft timing gear is installed on the bent axle of single cylinder diesel, idle gear is installed on the idle gear axle that is fixed on the body, camshaft timing gear is installed on the camshaft, crankshaft timing gear and idle gear engagement, idle gear and camshaft timing gear engagement.When the bent axle of single cylinder petrol engine rotates, drive idle gear by crankshaft timing gear and rotate, idle gear drives camshaft timing gear and rotates, and camshaft timing gear drives camshaft and rotates, thereby finishes the valve timing transmission of petrol engine.

Because the utility model gear quantity is few, Gear Processing technology is similar, therefore the utlity model has characteristics such as simple in structure, that the technology inheritance is good, and little investment is gone into operation soon, and cost is low.

Four, description of drawings

Accompanying drawing is the utility model schematic representation.

Five, specific embodiments

As shown in drawings, the utility model is made up of crankshaft timing gear (1), idle gear (2), camshaft timing gear (3) etc., crankshaft timing gear (1) is installed on the bent axle of diesel engine, idle gear (2) is installed on the idle gear axle that is fixed on the body, camshaft timing gear (3) is installed on the camshaft, crankshaft timing gear (1) and idle gear (2) engagement, idle gear (2) and camshaft timing gear (3) engagement.Crankshaft of diesel engine drives crankshaft timing gear (1), and crankshaft timing gear drives camshaft timing gear (3) by idle gear (2), and camshaft timing gear (3) drives camshaft, finishes the valve timing operation of diesel engine.

Concrete size between each gear of the present utility model is as follows:

Crankshaft timing gear (1) is 60～72mm with the perpendicular distance A of idle gear (2),

Crankshaft timing gear (1) is 10～20mm with the horizontal equivalent B of idle gear (2),

Crankshaft timing gear (1) is 58～70mm with the perpendicular distance C of camshaft timing gear (3),

Crankshaft timing gear (1) is 76～89mm with the horizontal equivalent D of camshaft timing gear (3).

The utlity model has simple in structurely, technology is inherited, small investment, it is fast to go into operation, cost is low wait special The point.

Claims (2)

1, a kind of cylinder diameter is the single cylinder diesel three gear trains of 80～92mm, it is characterized in that it includes crankshaft timing gear (1), idle gear (2), camshaft timing gear (3), crankshaft timing gear (1) is installed on the bent axle of single cylinder diesel, idle gear (2) is installed on the idle gear axle that is fixed on the body, camshaft timing gear (3) is installed on the camshaft, crankshaft timing gear (1) and idle gear (2) engagement, idle gear (2) and camshaft timing gear (3) engagement.

2, according to the said single cylinder diesel three gear trains of claim 1, it is characterized in that the concrete size between each gear is as follows:

Crankshaft timing gear (1) is 60～72mm with the perpendicular distance A of idle gear (2),
