Cross the investigation that the whole nation is the Eleventh Five-Year Plan period intended project under construction information, it is contemplated that at following 10 years, the market of small-diameter shield machine needed
The amount of asking will have good market prospect more than thousand.
Small-diameter shield machine inner space is limited, and equipment arranges that difficulty is big, the most main drive arrangement in center, for
The moment of torsion that offer is sufficiently large, needs base bearing bull gear number of teeth increase to provide higher gear ratio, can increase gear ring
Reference diameter, the size ultimately resulting in main driving is relatively big, so influences whether storehouse, people from top and the layout of lower section spiral shell machine.
Utility model content
The contradiction the least with space in order to solve main driving dimensions, this utility model provides a kind of straight at guarantee reference circle
On the premise of footpath, reduce the overall dimensions of main driving structure, increase the minor diameter of small-diameter shield machine internal unit arrangement space
The main driving structure that shield machine high transmission ratio high pulling torque realizes.
For realizing above-mentioned technical purpose, the technical scheme that this utility model is used is as follows:
The main driving structure that a kind of small-diameter shield machine high transmission ratio high pulling torque realizes, including driving box and some driving groups
Part, described driving box includes straight plate and curved wall, be arranged in parallel, and linked together by curved wall between described straight plate,
Making driving box profile is flat pattern；Assembly is driven to be symmetrically mounted on the inner side of curved wall.Driving box uses straight plate and arc
The structure of sidewall can reduce driving box occupied area in small-diameter shield machine, and the installation for other equipment provides convenient.
Described driving assembly includes motor, reductor, little gear, base bearing, external seal system, driving dish and interior sealing system
System；Motor is connected with reductor, and reductor is fixed on inside the curved wall of driving box, is provided with on the output shaft of reductor
Little gear, little gear engages with the external toothing of base bearing, and the inner ring of base bearing is fixed on driving box, and driving dish is connected to main shaft
On the outer ring held, external seal system and interior sealing system are installed between driving dish and driving box.
The external toothing of described base bearing and the inwall of driving box are provided with gap.Safety when gap assembles as base bearing
Surplus and reserve flow channel to gear oil.
Described external seal system and interior sealing system are lip-type packing.
The straight plate of described driving box to the distance at driving box center more than the external diameter of external seal system.
The number of teeth of described little gear is less than the external toothing number of teeth of base bearing.
Described base bearing uses three organ timbering roller bearings of band external toothing, it is possible to bear stronger tilting moment.
This utility model is engaged with the external toothing of base bearing by little gear and carries out transmitting moment of torsion, and the number of teeth of little gear is few
The number of teeth in the external toothing of base bearing, it is possible to improve gear ratio on the premise of transmission moment of torsion, the mode of external toothing can protected
On the premise of card reference diameter, the diameter making base bearing is less, and driving assembly is the left and right being symmetrically mounted on driving box
Both sides, can not install the straight plate structure of one-tenth provided above and below driving assembly by driving box, provide bigger to little shield machine
Arrangement space.
