Abstract
The utility model discloses an internal gear pipe for a rotary cultivator. The section of the internal gear pipe for the rotary cultivator is of a specially shaped structure; an outer wall of the internal gear pipe for the rotary cultivator is round; and a plurality of square slots are arranged on an inner wall of the internal gear pipe for the rotary cultivator in a concave manner, so that the whole inner wall is of a gear shape. The internal gear pipe for the rotary cultivator is high in strength, long in service life and high in fatigue durability.
Description
Technical field
The utility model relates to a kind of seamless steel pipe, relates in particular to a kind of rotovator and uses the internal gear pipe.
Background technology
Seamless steel tube production is one of national pillar industry, and along with development and national economy, the demand of seamless steel pipe is the trend of cumulative year after year.Seamless steel pipe is used to make structural members such as automobile, train, aircraft, steamer, space gun; And components of machine such as agricultural, mine, engineering, electrician, weaving, military project, seamless steel pipe civil area still be military industry field application all very extensively.Because the circular section steel pipe is stressed more even when bearing inside or outer radial pressure; So obtain a large amount of uses; But in many cases; The circular section steel pipe can not satisfy the specific instructions for use of structure member or mechanical part, therefore just needs extraordinary steel tubes come manufacturing structure parts or mechanical part, improves stock utilization and simplifies purposes such as production technology, shortening production cycle to reach.
Shape tube is compared with pipe, and the cross sectional shape of pipe is limited, has certain limitation; Can't be used for some specified conditions and environment, and shape tube has more the Economic Section advantage, adapt to the particularity of service condition; Can practice thrift metal; Improve stock utilization, simplify manufacturing process, raise labour productivity; Shape tube is compared with pipe, and shape tube all is superior to pipe in the overall appearance moulding and the design concept of product; Shape tube is compared with pipe, is satisfying under the conditions such as equal serviceability, and shape tube can alleviate construction weight greatly; The moment of inertia and the modulus of section of pipe are less, and under the condition that receives plain bending and distortion, it is big to be not so good as steel tubes bending strength and anti-twist ability; The pipe and the shape tube of the same length of side and diameter, shape tube bearing capacity and shock resistance are better; More than multiple reason limited the service condition and the scope of pipe; Under some particular surroundings and condition; Make structure member or mechanical part so adopt shape tube; For example: the rotovator rotating shaft has service conditions such as intensity height, long service life, fatigue durability are strong to part requirement, but also need possess complicated shape and structure miscellaneous part is played induced effect, therefore just can not adopt shape tube to make with pipe.
The utility model content
The utility model technical problem to be solved is: provide a kind of intensity height, long service life, rotovator that fatigue durability is strong to use the internal gear pipe.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of rotovator is used the internal gear pipe; Said rotovator is abnormally-structured with the cross section of internal gear pipe; Said rotovator is with the rounded setting of the outer wall of internal gear pipe, makes whole inwall formative gear shape thereby said rotovator is concaved with several square grooves with the inwall of internal gear pipe.
The beneficial effect of the utility model is: the rotovator in the utility model has advantages such as intensity height, long service life, fatigue durability be strong with the internal gear pipe, can be good at utilizing the inwall of body gear-like that the rotovator miscellaneous part is played gearing.
Description of drawings
Fig. 1 is the schematic cross-section of rotovator with the internal gear pipe.
Among Fig. 1: 1, square groove, 100, rotovator uses the internal gear pipe.
Embodiment
See also Fig. 1; A kind of rotovator is with internal gear pipe 100; Said rotovator is abnormally-structured with the cross section of internal gear pipe 100; Said rotovator is with the rounded setting of the outer wall of internal gear pipe 100, makes whole inwall formative gear shape thereby said rotovator is concaved with several square grooves 1 with the inwall of internal gear pipe 100.Said rotovator is processed by No. 35 steel with internal gear pipe 100, and through Quenching Treatment.
Rotovator in the utility model has advantages such as intensity height, long service life, fatigue durability be strong with internal gear pipe 100, can be good at utilizing the inwall of body gear-like that the rotovator miscellaneous part is played gearing.
Claims (2)
1. a rotovator is used the internal gear pipe; It is characterized in that: said rotovator is abnormally-structured with the cross section of internal gear pipe; Said rotovator is with the rounded setting of the outer wall of internal gear pipe, makes whole inwall formative gear shape thereby said rotovator is concaved with several square grooves with the inwall of internal gear pipe.
2. a kind of rotovator as claimed in claim 1 is used the internal gear pipe, it is characterized in that: said rotovator is processed by No. 35 steel with the internal gear pipe.
