Abstract

A deceleration structure of a hay cutter comprises a worm gear, a deceleration box body, a worm, a bearing seat, a main shaft, a worm-wheel shaft, a bearing cap and the like. The worm is installed at one end of the main shaft, the worm is engaged with the worm gear installed in the deceleration box body, and the worm is installed at the bottom of the deceleration box body through the bearing cap and the worm-wheel shaft which are arranged on the bilateral sides of the deceleration box body. Power is transmitted to the worm gear of the deceleration box body through the worm, and thus the hay cutter is decelerated, the power is conducted, and hay is cut fine.

Description

A kind of hay cutter slowing-down structure

Technical field

The utility model relates to mechanical aspects, is specially a kind of hay cutter deceleration conducting structure.

Background technique

The hay cutter tool of selling at present, because the speed reducer complex structure needs many axles, many to transmission between the gear, structure and installation are complicated, the kinetic energy conduction too much causes the energy loss problem, makes troubles also for installation and maintenance equipment.

Summary of the invention

For many manufacturings that the drive mechanism that solves the hay cutter complexity brings, maintenance, the problem of the too much loss of energy conduction are installed, the utility model provides a kind of hay cutter, when finishing quick hand hay cutter grass, and designs simplification, conduction is succinct, and power is powerful, installs simultaneously and keep in repair also fairly simple.

The technological scheme that the utility model is dealt with problems to be provided is achieved as follows: a kind of hay cutter slowing-down structure, formed by worm gear, deceleration box, worm screw, bearing support, main shaft, worm-wheel shaft, bearing cap, it is characterized in that: at main shaft one end worm screw is installed, worm screw and the worm gear engagement that is contained in the speed reducer, worm gear is installed in the speed reducer bottom by bearing cap and the worm-wheel shaft at speed reducer two ends.

The deceleration box of described a kind of hay cutter slowing-down structure is installed on the bearing support of supports main shaft, and the worm and worm wheel of spindle end are installed in the deceleration box entirely.

The dynamic retarding of the slowing-down structure of described a kind of hay cutter and conduction are to realize by conduction between worm gear and the worm-wheel shaft, and worm gear wheel footpath and worm-wheel shaft axle journal are than determining reduction speed ratio.

The beneficial effects of the utility model are: be transmitted to by worm screw on the worm gear of deceleration box, reduction range enlarges, thereby has realized the claimed range of hay cutter hand hay cutter grass, and meticulous grass is long; Simplified structure improves reliability, simplifies complexity is installed, and reduces cost.

Description of drawings

Fig. 1 is general assembly structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Among the figure, 1. worm gear, 2. deceleration box, 3. worm screw, 4. bearing support, 5. main shaft, 6. worm-wheel shaft, 7. bearing cap.

Embodiment

Such as Fig. 1, shown in 2, the utility model is by worm gear (1), deceleration box (2), worm screw (3), bearing support (4), main shaft (5), worm-wheel shaft (6), the compositions such as bearing cap (7), worm screw (3) is installed or main shaft (5) one ends are processed into worm screw (3) at main shaft (5) one ends, worm screw (3) and worm gear (1) engagement that is contained in the speed reducer (2), worm gear (1) is installed in deceleration box (2) bottom by bearing cap (7) and the worm-wheel shaft (6) at speed reducer two ends, deceleration box (2) is installed on the bearing support (4) of supports main shaft (5), and worm screw (3) and the worm gear (1) of main shaft (5) end are installed in the deceleration box (2) entirely.

Wherein power-converting and transmission are by disposable finishing between worm gear and the worm-wheel shaft, have reduced power conduction number of times, have simplified greatly internal structure, increase work efficiency.

Claims

1. hay cutter slowing-down structure, formed by worm gear, deceleration box, worm screw, bearing support, main shaft, worm-wheel shaft, bearing cap, it is characterized in that: at main shaft one end worm screw is installed, worm screw and the worm gear engagement that is contained in the speed reducer, worm gear is installed in the speed reducer bottom by bearing cap and the worm-wheel shaft at speed reducer two ends.

2. a kind of hay cutter slowing-down structure according to claim 1 is characterized in that deceleration box is installed on the bearing support of supports main shaft, and the worm and worm wheel of spindle end are installed in the speed reducer entirely.

3. a kind of hay cutter slowing-down structure according to claim 1 is characterized in that dynamic retarding and conduction are to realize by conduction between worm gear and the worm-wheel shaft, and worm gear wheel footpath and worm-wheel shaft axle journal are than determining reduction speed ratio.
