Description

The special-purpose turntable bearing of hose fed travelling sprinkler machine

Technical field

The utility model relates to a kind of special bearing, especially relates to a kind of special-purpose turntable bearing that is used for hose fed travelling sprinkler machine winch rack base support.

Background technology

In the agricultural mechanization water-saving irrigation technique, hose fed travelling sprinkler machine is the semi-automatic sprinkling machine of a kind of single shower nozzle commonly used.This irrigation sprinkler is the vehicular structure, is made up of shower nozzle car and winch truck two large divisions, and the two is linked to each other by the speciality polyethylene medium-soft pipe that is entangled on the capstan winch.During the water spray operation, the hydro powered machine on the capstan winch drives capstan winch and slowly rotates under pressure water action, and pipe is reclaimed, and the shower nozzle car is moved on limit, field water spray, limit.Until near winch truck the time, quit work automatically, finish the sprinkling irrigation operation in a bar field.Capstan winch is installed towards minute operation and transportation two states, when road transport, require capstan winch by the vertical half-twist in relative winch truck chassis, operating position make capstan winch twine tube side to winch truck lead one to, convenient transportation, when the sprinkling irrigation operation of finishing a bar field, when directly operation is sprayed water in another side slat field of irrigation sprinkler, require the vertical Rotate 180 in the relative winch truck of capstan winch chassis °.In order to realize that the relative winch truck of capstan winch chassis vertically rotates, guarantee its carrying and anti-cover ability just, and turn to reliably, light, the special-purpose turntable bearing of irrigation sprinkler of a vertical support is set between the frame pedestal of capstan winch and winch truck chassis.The turntable bearing that uses adopts the Internal and external cycle two-part construction at present, along the circumferential direction studs with steel ball in the middle of the Internal and external cycle, and inner ring, outer ring adopt the steel plate punch forming process to make, and needs the processing of design mold and adopts the special equipment assembling, and equipment investment is big.Some enterprises are also arranged directly from foreign procurement, cost an arm and a leg.Especially can not satisfy the requirement of hose fed travelling sprinkler machine small lot batch manufacture.Therefore there is the problem that the manufacturing process difficulty is big, investment is big, production cost is high.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provides the low hose fed travelling sprinkler machine of a kind of easy to manufacture, reduced investment and production cost special-purpose turntable bearing.

For achieving the above object, the utility model adopts following technical proposals: the special-purpose turntable bearing of hose fed travelling sprinkler machine of the present utility model comprises bearing outer ring, bearing inner race and steel ball.Described bearing inner race is formed by going up in the bearing to enclose down in circle and the bearing, be taken in the bearing and be contained in the bearing outer ring, enclose down in the described bearing and enclose by on bolt shaft is in being packed in bearing, and with bearing outer ring and bearing in go up circle and constitute square annular groove, in described square annular groove, stud with steel ball, four inner surfaces of square annular groove are tangent with steel ball respectively, the plane installs by sunk screw and connects dish on enclosing in described bearing, connects dish under the lower plane of described bearing outer ring installs by sunk screw.

As further improvement of the utility model, can be in described bearing on the inboard radial symmetric of circle two lubricating cups are installed, the installing hole of lubricating cup communicates with described square annular groove by inclined hole.

After adopting technique scheme, the beneficial effect that the special-purpose turntable bearing of hose fed travelling sprinkler machine that the utility model provides has is: since with special-purpose turntable bearing be designed to by go up in bearing outer ring, the bearing circle, bearing Nei Xiaquan, on connect dish, connect and coil five structures that disk body combines down, the all available machine tool processing of these parts, assembling can be finished with general tool, different batch production requirement can be satisfied.Thereby obtain effect easy to manufacture, that reduce investment outlay and reduce production costs.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

At Fig. 1, among Fig. 2 and Fig. 3, shown in the special-purpose turntable bearing of hose fed travelling sprinkler machine, comprise bearing outer ring, bearing inner race and steel ball, described bearing inner race is made up of circle 4 under going up in circle 2 and the bearing in the bearing, going up circle 2 in the bearing is sleeved in the bearing outer ring 8, circle 4 axially is packed in by bolt 5 and goes up on the circle 2 in the bearing under in the described bearing, and with bearing outer ring 8 and bearing in go up circle 2 and constitute square annular groove, in described square annular groove, stud with steel ball 6, four inner surfaces of square annular groove are tangent with steel ball 6 respectively, on in described bearing circle 2 on the plane install by sunk screw 3 and connect dish 1, the lower plane of described bearing outer ring 8 installs by sunk screw 7 under, connect and coil 9.Such structure adopts general tool just can enclose down and the steel ball assembly going up in bearing outer ring, the bearing in circle, the bearing.

As the another kind of embodiment that improves of the present utility model, can be as shown in Fig. 1, Fig. 4 and Fig. 5, the inboard radial symmetric of circle 2 is installed two lubricating cups 10 in described bearing, and the installing hole of described lubricating cup 10 communicates with described square annular groove by inclined hole 11.Can guarantee that it is wear-resistant, rotate flexibly by the order of classes or grades at school requirement by two lubricating cups 10 lubricating oil of in special-purpose turntable bearing, annotating like this.
