Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the high-strength gear for the large reduction gear box includes a gear body 10, a tooth space 12 is formed on the outer surface of the gear body 10 at the position of a gear tooth, the tooth space 12 is located between two adjacent gear teeth, and a disassembly section 13 is further disposed on one side of the gear body 10;

through tooth's socket 12, can go into inside with the connection tooth card of its meshing for the tooth of gear body 10 can receive the support of tooth's socket 12 lateral wall, thereby strengthens the intensity of gear tooth, and the external gear tooth who is connected with gear body 10 equally can receive the protection of tooth's socket 12, has avoided the problem of structural damage.

Wherein, the middle part position of gear body 10 is provided with integrated into one piece's connecting portion 11, and the central point of connecting portion 11 puts and sets up the spread groove 111 that runs through, and keyway 112 has been seted up to the inner wall of spread groove 111, and spread groove 111 is circular notch, and keyway 112 is the rectangle structure, penetrates the connecting axle through spread groove 111, inserts the key in keyway 112's position, uses as the key-type connection notch, plays fixed effect.

Wherein, the both ends of connecting portion 11 all protrude gear body 10's surface, and the height that connecting portion 11 both ends protrude gear body 10 surface is unanimous, guarantees that the hookup location of gear body 10 both ends face is unanimous, and convenient follow-up fixes gear body 10.

In order to facilitate the detachment of other gears engaged with the gear body 10, the detaching section 13 is a plurality of notches formed in one side of the gear teeth, the notches are communicated with the tooth spaces 12, and the notches and the tooth spaces 12 have the same shape, so that when the external gear is engaged with the gear body 10, the gear connected with the gear body 10 can be pushed out at the detaching section 13, and the engaging relationship between the gear body 10 and other gears is broken.

Wherein, the inside of gear body 10 is provided with strengthening rib 14, and strengthening rib 14 is a plurality of strip plate body, and the quantity of strip plate body is unanimous with the quantity of gear tooth, and every strip plate body all sets up in the inside central point of gear tooth and puts, provides the position restriction in inside through strengthening rib 14, further strengthens the intensity of its gear tooth.

The gear body 10 is made of medium-hardenability carburizing steel, the reinforcing ribs 14 are made of high-hardenability carburizing steel, the strength of the internal high-hardenability carburizing steel is higher, protection is further strengthened in the internal high-hardenability carburizing steel, and budget is reduced.

The working principle is as follows: when using, will not have the external gear of tooth's socket 12 and the meshing of gear body 10, the inside of tooth's socket 12 is gone into to external gear teeth card, and tooth's socket 12 has the support to the tooth of gear body 10 simultaneously, can be spacing to the external gear teeth, reduce the damage that it received, the intensity that can bear is higher, in addition through the strengthening rib that sets up, can provide the intensity in inside and support, further strengthen holistic intensity, and when needs are dismantled external gear, can rotate it to dismantlement section 13, the notch that matches with tooth's socket 12 is seted up to the position of dismantling section 13, can fall external gear from here, thereby accomplish the dismantlement, moreover, the steam generator is simple in structure, and convenient operation.
