Abstract
The invention discloses an anti-seepage sleeve of a gear shaft. The anti-seepage sleeve comprises a sleeve body (1), wherein a circle (2) is arranged at an opening of the sleeve body (1); the bottom of the sleeve body (1) is provided with a thread (3); and a step (4) is arranged between the thread (3) and the circle (2). The anti-seepage sleeve of the gear shaft, which is used in quenching, has the advantages of being convenient to mount and improved in anti-seepage quality, increasing the production efficiency and saving energy.
Description
Technical field
The present invention relates to a kind of gear shaft antiseepage cover.
Background technology
In manufacturing automobile gear axle process, thermal treatment is necessary operation.For the surface abrasion resistance that improves gear shaft, fatigue strength, heart section obdurability etc., usually adopt carburizing and quenching, and threaded portion is controlled hardness again, guarantee to surpass 38HRC, to guarantee the toughness of screw thread, avoid breaking and the fracture at thread place of thread.Anneal at the thread segment intermediate frequency after screw thread hardness usually adopts after the screw thread place is coated with permeability-reducing admixture carburizing and quenching or carburizing and quenching in order to control now.Employing is carburizing and quenching after the screw thread place is coated with permeability-reducing admixture, has increased labor capacity, and permeability-reducing admixture belongs to the fluidity material, the deviation in antiseepage zone may occur, can not realize the consistence of product, and product appearance has obvious antiseepage vestige; Medium frequency quenching behind the employing carburizing and quenching has increased operation equally, also need drop into intermediate frequency equipment, and is all high to equipment and personnel's requirement, and the energy has been wasted in intermediate frequency annealing again.
Summary of the invention
A kind of gear shaft antiseepage cover that uses when quenching provided by the invention, it is convenient that this frock clamp has installation, improves the antiseepage quality, enhances productivity the advantage of save energy.
The present invention has adopted following technical scheme: a kind of gear shaft antiseepage cover, comprise body, and be provided with circle at the opening part of body, be provided with screw thread in the bottom of body, be provided with step between described screw thread and the circle.
Described body is cylindric.
The present invention has following beneficial effect: it is convenient that the present invention has installation, improves the antiseepage quality, enhances productivity, save energy, the advantage such as reusable is screwed in during quenching on the screw thread that needs antiseepage, reach the purpose of antiseepage, thereby reach the purpose of control hardness.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention provides a kind of gear shaft antiseepage cover, comprise body 1, body 1 is cylindric, opening part at body 1 is provided with circle 2, the length of circle 2 is half of main drive shaft hardness transition zone, is provided with screw thread 3 in the bottom of body 1, screw thread 3 and main drive shaft thread fit, be provided with step 4 between described screw thread 3 and the circle 2, the step of screw thread closely cooperates on step 4 and the main drive shaft.
Claims (2)
1. a gear shaft antiseepage cover is characterized in that comprising body (1), is provided with circle (2) at the opening part of body (1), is provided with screw thread (3) in the bottom of body (1), and described screw thread (3) is provided with step (4) with justifying between (2).
2. a kind of gear shaft antiseepage cover according to claim 1 is characterized in that described body (1) is cylindric.
