Abstract
The utility model discloses a kind of mud water balance push bench eccentric gear mechanism and there is the push-bench of this mechanism, belong to technical field of engineering machinery.The feature of this eccentric gear mechanism establishes asbestos packing between described taper cutterhead dative screen, and described wear ring is made up of matrix and wear-resisting ring, and wear-resisting ring is fixed on the inner side of matrix, and the end face of wear-resisting ring and the end face of matrix flush.Advantage is novel, and structure letter is gathered, rationally; The wear ring of this gear mechanism in use, wear and tear little, in addition asbestine packing, thoroughly to sealing gap, eccentricity gear good sealing effect, lubricant oil not easily reveals and mud not easily enters gear tank, ensure that main bearing uses normal, the consumption of spare part spare unit is few, reduces cost of production, ensures to produce to carry out smoothly.
Description
Technical field
The utility model belongs to technical field of engineering machinery, particularly relates to a kind of eccentric gear mechanism of mud water balance push bench and has the mud water balance push bench of this mechanism.
Background technique
Mud water balance push bench possesses the function of broken gravel (drift) stone and soft rock, therefore can the extensive subsurface soil condition of accommodation, and such as cohesive soil and sand gravel, gravel mix land pebble and soft rock etc.The mud water balance push bench eccentric gear mechanism of current use comprises gear, ring gear, housing, bearing and Sealing and forms, gear is bolted in taper on dish, establish in ring gear is fixed on the housing of bearing, gear engages with ring gear, the mechanical seal be made up of wear ring and holddown spring outside ring gear and between taper cutterhead, holddown spring is fixed on taper cutterhead, and wear ring is sleeved on holddown spring, and wear ring is close to ring gear and seals gear.Problems existing is wear ring under eccentric, that vibrations are larger condition, and serious wear, causes being in unstable contact condition with opposing friction surfaces, and the tracing ability of wear ring opposing friction surfaces is not enough, causes oil leak; Part mud enters gear tank by the gap of Sealing and end cap, easily causes main bearing to damage, and the consumption of spare part spare unit is large, and cost of production increases, and engineering time is long, is unfavorable for normal production work.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of mud water balance push bench eccentric gear mechanism, eccentricity gear good sealing effect, wear and tear little, lubricant oil not easily reveals and mud not easily enters gear tank, ensure that main bearing uses normal, the consumption of spare part spare unit is few, reduces cost of production, ensures to produce to carry out smoothly.
Mud water balance push bench eccentric gear mechanism, comprise gear, ring gear, housing and bearing are formed, gear is bolted on taper cutterhead, establish in ring gear is fixed on the housing of bearing, gear engages with ring gear, the mechanical seal be made up of wear ring and holddown spring outside ring gear and between taper cutterhead, holddown spring one end is fixed on ring gear, the other end is fixed on taper cutterhead, wear ring is sleeved on holddown spring, wear ring is close to ring gear, be characterized in establishing asbestos packing between described taper cutterhead dative screen, described wear ring is made up of matrix and wear-resisting ring, wear-resisting ring is fixed on the inner side of matrix, the end face of wear-resisting ring and the end face of matrix flush.
The utility model improves further, and described wear-resisting ring is carborundum ring, and wear-resisting ring embeds in matrix.
Another object of the utility model is to provide a kind of mud water balance push bench with this eccentric gear mechanism.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; The wear ring of this gear mechanism in use, wear and tear little, in addition asbestine packing, thoroughly to sealing gap, eccentricity gear good sealing effect, lubricant oil not easily reveals and mud not easily enters gear tank, ensure that main bearing uses normal, the consumption of spare part spare unit is few, reduces cost of production, ensures to produce to carry out smoothly.
