Abstract
The utility model is related to a kind of drilling machine head cases.The transmission device includes the steel gear of cooperation（1）And nylon gear（2）, the nylon gear（2）Including inner sleeve（21）And external gear（22）, the inner sleeve（21）It is made of nylon, the external gear（22）It is made of nylon and glass fibre.Nylon gear is separately set by the utility model, that is inner sleeve and external gear, wherein external gear is made of nylon and glass fibre, so enhance the intensity and wearability of nylon gear, improve the service life of nylon gear, simultaneously using inner sleeve and the structure type of external gear, the use cost of nylon gear is also reduced, there is good economy.
Description
Technical field
The utility model is related to a kind of drilling machine head cases, belong to drilling machine technical field.
Background technology
The gear drive of existing product, using a steel gear and the kind of drive of nylon gear collocation, this
The advantages of kind kind of drive is that stable transmission, noise is small, and the torque of output is steady；Use a period of time, it has been found that this
Transmission exist it is one very big the defects of, when lathe load excessive or convert cutting direction when, nylon gear is easily damaged, and is led
The security performance of lathe is caused to substantially reduce.
Utility model content
The utility model can increase substantially gear use in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of rational in infrastructure
The drilling machine head case in service life.
The technical solution adopted in the utility model is therefore：The utility model includes transmission device, the transmission device
Steel gear including cooperation（1）And nylon gear（2）, the nylon gear（2）Including inner sleeve（21）And external gear（22）, it is described
Inner sleeve（21）It is made of nylon, the external gear（22）It is made of nylon and glass fibre.
The inner sleeve（21）, external gear（22）Corresponding connecting hole is respectively arranged on upper surface, lower surface（3）, set
There is gate connector（4）Through the connecting hole（3）Form inner sleeve（21）, external gear（22）Connection.
The inner sleeve（21）And external gear（22）Radially it is provided with radial direction fastener hole（5）, it is provided with fastener（6）
Through the fastener hole（5）Form inner sleeve（21）And external gear（22）Connection.
The inner sleeve（21）Fastener hole（5）Formed stepwise, the fastener（6）Indent is in inner sleeve（21）Inner surface
It sets.
The utility model has the advantages that：1）Nylon gear is separately set by the utility model, i.e. inner sleeve and external gear, wherein
External gear is made of nylon and glass fibre, so enhances the intensity and wearability of nylon gear, improves nylon gear
Service life, while using inner sleeve and the structure type of external gear, also reduce the use cost of nylon gear, have good
Economy；
2）The connection mode of the further nylon gear of the utility model and steel gear is simple in structure, good connecting effect, makes
Connection between nylon gear and steel gear is very reliable and easy to operate, and the utility model nylon gear and
The connection mode of steel gear will not have any impact to the transmission of the two.

Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of the utility model nylon gear.
1 it is steel gear in figure, 2 be nylon gear, 3 be connecting hole, 4 be gate connector, 5 be fastener hole, 6 is fastening
Part；
21 it is inner sleeve, 22 is external gear.
Specific embodiment
The utility model includes transmission device, and the transmission device includes the steel gear 1 of cooperation and nylon gear 2, institute
Stating nylon gear 2 includes inner sleeve 21 and external gear 22, and the inner sleeve 21 is made of nylon, and the external gear 22 is by nylon and glass
Fiber is made.
The inner sleeve 21,22 upper surface of external gear are respectively arranged with corresponding connecting hole 3 on lower surface, are provided with gate
Connector 4 forms the connection of inner sleeve 21, external gear 22 through the connecting hole 3.
The inner sleeve 21 and external gear 22 are radially provided with radial direction fastener hole 5, are provided with fastener 6 described in
Fastener hole 5 forms the connection of inner sleeve 21 and external gear 22.
5 formed stepwise of fastener hole of the inner sleeve 21,6 indent of fastener are set in 21 inner surface of inner sleeve.
When the utility model is used, first external gear 22 is set in inner sleeve 21, then passes through gate connector 4, fastening
Part 6 links together external gear 22 and inner sleeve 21, coordinates so as to fulfill the transmission of inner sleeve 21 and external gear 22.
The gate connector 4 and fastener 6 of the utility model are arranged symmetrically, so that both inner sleeve 21 and external gear 22
Attachment force symmetrically and evenly, ensure the connection reliability of inner sleeve 21 and external gear 22, also improve inner sleeve 21 and external gear 22
Force environment, improves reliable transmission and the stationarity of nylon gear 2 and steel gear 1, and extends steel gear 1 and nylon gear
2 service life.
