Description
Technical field
The invention belongs to measuring instrument technical field, especially relate to a kind of for theodolite or total powerstation
Vertical pivot bearing arrangement.
Background technology
At present, along with the development of science and technology, measuring instrument is constantly weeded out the old and bring forth the new, and new instrument gives each row each
Industry brings a lot of facilities, also saves the substantial amounts of measurement time simultaneously, improves the precision of measurement,
The most just have theodolite and total powerstation both measuring instruments, described theodolite be a kind of measure horizontal angle and
The instrument of vertical angle, has the highest certainty of measurement and the feature being easy to use and carrying；Described total powerstation
It is a kind of to integrate light, mechanical, electrical high-tech measuring instrument, is collection horizontal angle, vertical angle, distance
(oblique distance, flat away from), vertical survey function are in the instrument of surveying and mapping system of one.Above above-mentioned instrument one
Individual critical piece is exactly vertical pivot structure, and existing vertical pivot is all to use " half campaign-styled columnar shaft " structure,
As it is shown in figure 1, vertical pivot a is outside equipped with axle sleeve b, it is provided with between axle sleeve b top and the vertical pivot a shaft shoulder
Ball c, axle sleeve b bottom inside coordinates with vertical pivot a, forms precision-fit position e, trim ring d and arranges
In axle sleeve b bottom, match with vertical pivot a；This is a typical structure, it is possible to meet theodolite or
The requirement of total powerstation, but, this structure is the highest to material, heat treatment, requirement on machining accuracy, right
Require the highest in processing staff's operating technology, additionally, matching part hardness is HRC62～63, the highest
Hardness want polish only with grinding machine grind, be unfavorable for batch production, cost is the most of a relatively high.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of reduction difficulty of processing and processing cost, it is achieved batch is raw
Produce, stop the vertical pivot bearing arrangement for theodolite or total powerstation of axis phenomenon.
For solving above-mentioned technical problem, the technical solution used in the present invention is: one is for theodolite or complete
Stand the vertical pivot bearing arrangement of instrument, including vertical pivot and axle sleeve, between described vertical pivot and axle sleeve the most successively
Being provided with clutch shaft bearing, the second bearing and trim ring, described clutch shaft bearing upper end is by being positioned at same level
The vertical pivot shaft shoulder and axle sleeve inner ring boss location, described second bearing lower end is positioned by trim ring；Described pressure
Circle includes that the first trim ring and the second trim ring, described first trim ring are closely arranged at below the second outer race,
Described second trim ring is closely arranged at below the second bearing inner ring；Between described first trim ring and the second trim ring
Leave space.
It is provided with spacer ring between described clutch shaft bearing outer shroud and the second outer race.
It is stepped outside described axle sleeve.
Owing to using technique scheme, this structural member uses finish turning to substitute fine grinding, and counterpart uses precision
Higher bearing, the hardness of bearing own is the highest, and other structural members are with car generation mill, due to Production of bearing batch
Very big, homogeneity of product is the best, and stable accuracy, cost can reduce by 50%；And difficulty of processing reduces,
Easily mass production；The half easy axis of campaign-styled columnar shaft in the past, but the vertical pivot of the present invention changes
The overall structure of conventional vertical pivot, adds bearing arrangement simultaneously, there is not axis phenomenon.
The invention has the beneficial effects as follows: there is reduction difficulty of processing and processing cost, it is achieved batch production,
The advantage stopping axis phenomenon.
Accompanying drawing explanation
Below with reference to accompanying drawing and combine example and be specifically described the present invention, advantages of the present invention and realization
Mode will become apparent from, and wherein content shown in accompanying drawing is only used for explanation of the present invention, and not structure
The restriction gone up in all senses of the present invention in pairs, in the accompanying drawings:
The structural representation of vertical pivot in Fig. 1 prior art
The structural representation of Fig. 2 present invention
In figure:
1, vertical pivot 2, axle sleeve 3, clutch shaft bearing
4, second bearing the 5, first trim ring the 6, second trim ring
7, spacer ring 8, the vertical pivot shaft shoulder 9, axle sleeve inner ring boss
31, clutch shaft bearing outer shroud the 41, second outer race the 42, second bearing inner ring
Detailed description of the invention
As in figure 2 it is shown, a kind of vertical pivot bearing arrangement for theodolite or total powerstation of the present invention, including erecting
Axle 1 and axle sleeve 2, be from top to bottom disposed with between described vertical pivot 1 and axle sleeve 2 clutch shaft bearing 3,
Second bearing 4 and trim ring, described clutch shaft bearing 3 upper end is by being positioned at the vertical pivot shaft shoulder 8 of same level
Positioning with axle sleeve inner ring boss 9, described second bearing 4 lower end is positioned by trim ring；Described trim ring includes
First trim ring 5 and the second trim ring 6, described first trim ring 5 is closely arranged at below the second outer race 41,
Described second trim ring 6 is closely arranged at below the second bearing inner ring 42；Described first trim ring 5 and second
Space is left between trim ring 6；It is provided with between described clutch shaft bearing outer shroud 31 and the second outer race 41
Spacer ring 7；It is stepped outside described axle sleeve 2.
The work process of this example: this structural member uses finish turning to substitute fine grinding, counterpart uses precision higher
Bearing, owing to Production of bearing batch is the biggest, homogeneity of product is the best, and stable accuracy, cost can
Reduce by 50%；And difficulty of processing reduces, easy mass production；Half campaign-styled columnar shaft in the past is easy
Axis, but the vertical pivot of the present invention changes the overall structure of conventional vertical pivot, adds two bearings simultaneously
, there is not axis phenomenon in structure.
Above embodiments of the invention are described in detail, but described content has been only the preferable of the present invention
Embodiment, it is impossible to be considered the practical range for limiting the present invention.All according to the scope of the invention made equal
Deng change and improvement etc., within all should still belonging to this patent covering scope.
