Abstract

The utility model discloses the connection structures that a kind of anti-bearing of filter-press runs inner ring, including rolling bearing and rotary drum axis, rolling bearing and the transmission connection of rotary drum axis, rolling bearing is set in rotary drum axis outer peripheral surface, it is respectively cooperating on the bearing inner race and rotary drum axis of rolling bearing and is recessed with keyway, flat key is equipped in keyway, so that the bearing inner race and rotary drum axis prevents bearing inner race under the active force of flat key and rotary drum axis produces relative sliding in rolling bearing transmission.The connection structure that the anti-bearing of the filter-press runs inner ring avoids bearing race inner ring, effective protection rotary drum axis not frayed, substantially reduces maintenance cost and maintenance load.

Description

A kind of anti-bearing of filter-press runs the connection structure of inner ring

Technical field:

The utility model relates to a kind of filter-presses, are especially a kind of connection of anti-bearing race inner ring of filter-press Structure.

Background technique:

Filter-press is equipment necessary to petroleum chemical enterprise, and the spring bearing part for being mainly characterized by filter rotary drum is complete Portion is included within pressure housing, supports the bearing block of rotary drum using rolling bearing structure.Since bearing bore diameter is larger, for convenient for Installation.The matching allowance for designing upper bearing (metal) and rotary drum axis is less than normal.It can be lost in the longtime running rear bearing sealing of filter-press Effect, bearing, which enters powder, causes insufficient lubrication, bearing rotation bite.Under the torque of axis, causes bearing and run inner ring, rotary drum axis Wear-out failure.Device production is influenced, maintenance cost is expensive after drum Abrasion.Heavy losses are caused to company.

Utility model content:

Technical problem to be solved by the utility model is to provide one kind, and bearing to be avoided to run inner ring, effective protection rotary drum axis Not frayed, the anti-bearing of filter-press for substantially reducing maintenance cost and maintenance load runs the connection structure of inner ring.

The technical solution of the utility model is to provide a kind of connection structure of anti-bearing race inner ring of filter-press, Including rolling bearing and rotary drum axis, rolling bearing and the transmission connection of rotary drum axis, rolling bearing are set in rotary drum axis outer peripheral surface, rotate It is respectively cooperating on the bearing inner race and rotary drum axis of bearing and is recessed with keyway, be equipped with flat key in keyway, so that being passed in rolling bearing Bearing inner race and rotary drum axis prevents bearing inner race under the active force of flat key and rotary drum axis produces relative sliding when dynamic.

After using the above structure compared with prior art, the utility model has the advantage that in rolling bearing transmission Bearing inner race and rotary drum axis prevent the two under the active force of flat key and produce relative sliding, and avoid bearing and run inner ring failure, real Now extend filter-press continuous operating time, enhance equipment dependability, effective protection rotary drum axis is not frayed, drops significantly Low maintenance cost and maintenance load reduce the influence to continuity chemical company steady production at full capacity.

Preferably, flat key is the stainless steel flat key of 110mm*25mm*14mm.The intensity and stiffness for meeting key, avoid by Load, impact, shearing force failure.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment:

The utility model is described in further detail with reference to the accompanying drawings and detailed description:

As shown in Figure 1, a kind of anti-bearing of filter-press runs the connection structure of inner ring, filter-press manufacturing firm be at Filter plant Co., Ltd, Yunxiang, the connection structure include rolling bearing 2 and rotary drum axis 3, and rolling bearing 2 and rotary drum axis 3 are driven Connection, rolling bearing 2 are set in 3 outer peripheral surface of rotary drum axis, are respectively cooperating with and are recessed on the bearing inner race and rotary drum axis of rolling bearing 2 Keyway, keyway are oppositely arranged, and are equipped with flat key 1 in the cavity of two keyways formation, so that the bearing in rolling bearing transmission Inner ring and rotary drum axis prevent bearing inner race under the active force of flat key and rotary drum axis produces relative sliding.For meet key intensity and Stiffness, avoids loaded, impact, shearing force failure, and flat key is the stainless steel flat key of 110mm*25mm*14mm.

Bearing type of the utility model with keyway substantially prolongs equipment continuous operation because of the improvement on driving form The advantages of period, in rolling bearing transmission, it is relatively sliding to prevent the two generation under the active force of flat key for bearing inner race and rotary drum axis It is dynamic, it avoids bearing and runs inner ring failure, realize and extend filter-press continuous operating time, enhance equipment dependability, effectively It protects rotary drum axis not frayed, greatly reduces maintenance cost and maintenance load, reduce full to continuity chemical company The influence of steady load production.

Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this Within the scope of patent protection of utility model.

Claims
