Abstract
The utility model provides a kind of agricultural machinery steering gear, belongs to field of mechanical technique.It solves existing conventional steering gear on the market to reduce the gyration aperture increase accuracy of gear so that the complex price of its structure is high, the problem of increasing the production cost of enterprise.The steering gear of this agricultural machinery, it is arranged in a mutually vertical manner including casing and two in the gear shaft in casing, two gear shafts by the end gear teeth be meshed transmission and gearratio be 1: 1, the neck of gear shaft is provided with deep groove ball bearing and junction is arranged with positioning retainer ring and adjusting gasket, the head of gear shaft stretches out that casing is outer and afterbody be located at that casing is interior to be connected by needle bearing, and the dirt-proof boot being engaged with gear shaft is additionally provided with casing.The advantages of the utility model has production cost simple in construction low and gone slick.
Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of steering gear, more particularly to a kind of agricultural machinery steering gear.
Background technology
Steering gear is that a kind of steering moment from steering wheel and steering angle carry out the driver that proper transformation exports again
Tool, classify according to assist type, steering gear can be divided into mechanical and dynamical type, because mechanical middle gear formula steering gear has
It is simple and compact for structure, rigidity is big, cost is cheap and the advantages that being easy to arrangement, therefore generally all using mechanical on farm machinery
Steering gear, but the steering gear of routine increases the accuracy of gear to reduce gyration aperture on the market so that its structure is complex
Price is high, increases the production cost of enterprise, and the requirement to steering gear precision in farm machinery is relatively low, therefore appropriate essence
The structure of simple steering gear, which reduces cost, can better meet the demand of market user.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of production simple in construction
Cost is low and the agricultural machinery steering gear that goes slick.
The purpose of this utility model can be realized by following technical proposal：A kind of agricultural machinery steering gear, including casing and two
It is individual to be arranged in a mutually vertical manner in the gear shaft in casing, it is characterised in that two described gear shafts are meshed biography by the end gear teeth
Dynamic and gearratio is 1: 1, and the neck of the gear shaft is provided with deep groove ball bearing and junction is arranged with positioning retainer ring and regulation
Pad, the head of the gear shaft stretches out that casing is outer and afterbody be located at that casing is interior to be connected by needle bearing, described casing
On be additionally provided with the dirt-proof boot being engaged with gear shaft.
The technique effect of this agricultural machinery steering gear is：Two gear shafts are engaged by the straight bevel gear direct connection of end, structure letter
Single-drive efficiency high, and gearratio is 1: 1, the wherein modulus of the gear shaft is 3.25, the number of teeth 16, preferably adds this turn
To the versatility of device, because periphery dust is more when farm machinery is run, dirt-proof boot is set effectively to prevent ash on casing
Dirt, which enters, increases its service life inside steering gear.
In a kind of above-mentioned agricultural machinery steering gear, the both ends of the gear shaft offer centre bore respectively.Pass through centre bore
Gear shaft can be made, and precision is higher after processing.
In a kind of above-mentioned agricultural machinery steering gear, the material of the gear shaft is 20CrMnTi steel alloys.
Compared with prior art, the advantages of steering gear of this agricultural machinery has production cost simple in construction low and gone slick.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, the steering gear of this agricultural machinery, including casing 1 and two are arranged in a mutually vertical manner in the gear shaft 2 in casing 1,
Two gear shafts 2 are meshed transmission by the end gear teeth and gearratio is 1: 1, the neck of gear shaft 2 be provided with deep groove ball bearing 3 and
Junction is arranged with positioning retainer ring 4 and adjusting gasket 5, the head of gear shaft 2 stretches out that casing 1 is outer and afterbody be located in casing 1 it is logical
Cross needle bearing 6 to be connected, the dirt-proof boot 7 being engaged with gear shaft 2 is additionally provided with casing 1.
Further describe in detail, in order that precision is higher after processing for gear shaft 2, the both ends of gear shaft 2 offer center respectively
Hole 8；Wherein the material of the gear shaft 2 is 20CrMnTi steel alloys.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although casing 1, gear shaft 2, deep groove ball bearing 3, positioning retainer ring 4, adjusting gasket 5, rolling have more been used herein
The terms such as needle bearing 6, dirt-proof boot 7, centre bore 8, but it is not precluded from the possibility using other terms.Using these terms only
It is to more easily describe and explain essence of the present utility model；Be construed as any additional limitation be all with
The utility model spirit is disagreed.
